- We got our hands on this lovely old watch from 1972, a Grand Seiko GS61 that is in need of a service and a new crystal. In this video we will run through the full service of this fabulous watch and talk a bit about what the beat rate means in practice. And we'll use a hammer completely unnecessarily!

The metal finishing and machining on this Grand Seiko looks very fine. Glad you shared this so we can see that Seiko can produce an aesthetically handsome movement.
Hi Frank, yes, this is indeed a more refined finishing than many old Seiko's. If you look at new high grade Seiko's, you will also see nice finishing there. This whole watch is very, very nice :)
D0nt like hi beat watches they wear out fast, service is also needed at short terms
When my dad passed away we donated the "box of dead Seiko" he had cummulated for years, since 1969 iirc. I kept his Swiss watches but now I've come to regret the Seiko box...
I've always adored the term 'key-less works'.
I'm writing this on the train as my 'horse-less carriage' is in for service.
You’re a talented watch maker and it’s a privilege to watch. You’re also a good narrator. Very good videos. Respect.
Thanks so much, Michael :)
The narration and knowledge is very enjoyable, I came for the lessons but stayed for personality (:
I've been watching a lot of watchmaking channels because one day I'd like to be able to do more by myself since a big harem of sexy watches is costly to maintain, not even considering the delays for parts & waiting for a qualified watchmaker to take on "your project"
I have no illusions about my lack of knowledge but you're very inspiring to fellow collectors, at least me 😊
Another gorgeous Seiko watch. Found it interesting that the spring barrel had a do not open sign on it.
I had a golden brown faced one with square faceted crystal. Absolutely gorgeous. So sad I passed it on. Haven't seen one since. I love the crystal shape with the face.
I recently purchased an old 6145-8010, my first automatic watch. Couldn’t find much information on it, but found this video and have watched it twice now. I’m really enjoying learning about these watches, they’re just so fascinating and these servicing videos are relaxing and satisfying.
Much respect for your skills and patience; I was about to lose my mind just from changing the strap on my new watch!😂
😁
I have the King Seiko with the same ramped indicies. Not a huge fan of the faceted glass. But still, an amazing piece. I didn't realize that Grand Seikos had this dial. Shows how much King and Grand had in common
Nice to see GS history being taken so well care of. I'd be interested in your take on GS's Spring Drive movement.
I don't have a 6145-8050 but I do have a 6146-8050 with the day-date version, April 1972. Facetted glass like this one. Silver dial. Absolutely love it.
As usual, an addicting video of meticulous detail. Just fascinating.
Thanks so much, Dave :)
Wow, I didn't know how smooth the high beat movements were - they make pretty much every other purely mechanical movement look more jittery. That jump from 28,800 to 36,000 bph is crazy! I've wanted a GS for a while and have been wanting a spring drive one - but after watching this, I won't discount a high beat!
Thanks, Haseeb! There is a difference for sure, and a Seiko hi-beat 36000 is certainly something for any collection :)
Another excellent video. Don't sell yourself short, I come for you, my friend.
Thanks Donny! There'll be a lot more to come :)
I'm a real Fan of the Seiko Watches.
Great video! Thanks again!
Glad you like them! There'll be a lot more Seiko videos coming 👍
The watch dial is awesome
Great job and a cool watch. I'd never seen that crystal before. Thank you for your time and knowledge!
Thanks Chris, I really love this watch also, it's just a very cool and different design. Quite 70s, but the best kind of 70s 😁
Fabulous, I love it and I want one. Would be great addition to my collection. Thanks for sharing, Stian.
Wow, you get all the gems in! Gorgeous, great job.
Thank you! 😊
Nice watch and nice work ! Those GS are some exquisite watches!
Yes they are! And this reference in particular is very different from the rest of the GS's, very cool :)
Amazing work and skill, bravo 👏
Thank you so much 😀
Another great service on a beautiful watch. Love the GS's and this one does look sharp. They do, do a great watch.
Nicely done sir.
Thank you kindly :)
Fantastic watch and Watchmaker…. Thank you.
Thanks a lot Nigel 😊
I concur with you wholeheartedly about the dial of this unique Seiko being outstandingly gorgeous. Oh! How I wish Seiko would opt to use this rare color scheme on any one of their Lassale models back in the 1980's. Or even on one of the Credor rectangular models from the 1990's.
What an absolutely beautiful watch! That dial is breathtaking!
One thing I noticed, and maybe it's just my lack of experience, but the balance hack actually fouls the escape wheel instead of the balance or pallets. I think that is a rather ingenious design, putting that much less stress on the escapement.
You do such great work, and, as always, teach us more about these movements and watches in general. Thank you so much.
Hello Michael, thanks for watching and for your comment, very much appreciated! Yes, it certainly is a beauty. Very different and almost all in a good way :)
The hack might look like it will foul the escape wheel but it actually still stops the balance wheel when the stem is pulled out into hand setting mode. It's the safest place to stop the movement, as it stops the final movement component rather than one earlier in the chain. If the hack stopped the escape wheel, the balance wheel would still swing a couple of times and you might risk other problems. With the balance wheel arrested, everything stops immediately and it will also start up again immediately.
There are more videos coming, so stay tuned! 😁
nice and informative video! Great watch too.Thank you!
Thanks so much, Nick! More to come after the summer vacation, so stay tuned :)
Very informative and entertaining.
Glad you enjoyed it!
My favourite watchmaking channel. When my golf game is eventually in the bin, this is my next hobby.
Wow, thanks so much, Jerry, that's awesome to hear! Golf and watchmaking are very compatible though, so no need to wait 😉
My late uncle was a watchmaker and I have his tools, i think I'll get a cheap watch and have a tinker. Good luck with your channel.
Great job on the watch - and the “Hai” really surprised me! Great response in Japanese.
😂 I had a Japanese classmate in university, and once I said his name very fast (last name, first name) with a gruff voice and he immediately and instinctively responded "hai!". That's where I got it from :)
Even from 70s I can still see that Seiko DNA that is used in our poor man's movement from NH family. I am not an expert but one can see that the GS made this movement good. That jewel on the drive train plate where the main spring arbour sticks out. Thanks for sharing this video, I doubt we'll see GS movement often.
Thanks for watching! There's indeed clear DNA from the earlier movements to the modern ones, and Seiko still make great ones :)
I watch TH-cam almost exclusively on Amazon FireTV which is not comment friendly therefore I don't typically read or write comments. But I watch and enjoy every video please keep them coming. It's a. Welcome change to learn from a true professional and the background, history and insights are the best part. I've learned so much and thanks for not bashing Seiko so much. If you're ever bored or running out of content please feel free to take apart a Russian watch.
Hi Eric, thanks so much for making the effort to write a comment! I actually hold Seiko in very, very high regard, even though I might bash them for plastic parts, keyless works having hundreds of little pieces and their often rough finishing... But they make some very solid, no non-sense movements that I really respect. I even stated in one video that a Patek Philippe without the finishing would be a Seiko 😄
I'm actually planning to do a Russian or Soviet watch shortly, just have to decide whether to make it a chronograph or one I have lying around in a drawer somewhere. And I cannot promise to hold back on the bashing then!
You say that you prefer originality, but then replace the crystal. I would have liked to see you give the case a little love too. It would have gone from great to outstanding. Beautiful piece.
Thanks for watching! Yes, I replaced the non-original crystal with an original one 😉
A stunning watch and great video. I've noticed other guys have opened the "Do Not Open" mainspring barrel (and closed them again) with success.
Thanks, Red! Yes, you can open the "Do not open" barrels, but the risk of not being able to fit them again is quite high, so if it works well the safest thing is to keep it. If the mainspring does not give enough power I would certainly open it up (and find a reserve barrel just in case).
@@VintageWatchServices OK got ya. And I guess finding a similar barrel isn't easy.
ÓTIMO SERVIÇO 👍👍 🇧🇷
another expensive mistake made by seiko
I have a zenith el primero HW with a high beat rate. I only give it a run occasionally, because I don't know when it was last serviced, and I'm not good enough to service it. Cataracts and tremors, no good now for watch repairs. I do work on my pocket watches though. Great Channel, thank you.
Thanks John! The El Primero is indeed a bit of a challenge for shaky hands...
I really enjoyed this and learn a lot from you sir. This simple movement I guess which is good it has much less moving parts than let say a chronograph
Thanks a lot! There's indeed more parts the more complications you have and some watches have up to 600 parts... 😳
@@VintageWatchServices how about speedmaster with 1861 movements? I know they are complicated buy are they easier chrono to service??
Lots of good info.
Thanks Ronald!
Very good work ;-)
Very nice. Thank you
My pleasure, thanks for watching! 😊
Thank you - great video about great movement. Jokes are not bad sometimes 👍
Thanks! And darn it, I'm doing my best to keep the jokes bad! 😁
The right tool is half the work 😎
Ha…. Grand Seiko is on my wish list. Maybe later when I retire.
Another great video! I have a Sportmatic 5 6199A that I’m trying to fix the date functions. Would be great if you ever do a video on one.
Thanks Boyd! I basically work on the watches I have at any given time, so we'll see what comes across my desk :)
Thank you very much for another thoroughly enjoyable, educational and satisfying video! BTW, your pronunciation of Seiko sounds a lot like SAIKOH which means "the best" in Japanese. What a coincidence!!
Thanks for your comment and for the info! My Japanese is indeed a bit rusty 😉
Sounds like he's saying psycho. Haha.
I like my cases polished and restored, if possible. I keep the watches in my collection. When I go, I don't care how much they are worth.
To me personally it's not that much about the worth, it's more that I prefer things to be original, but for selling watches the originality is also more valuable :)
Very handsome piece. Top job getting it at 0
Ooooh!! I was 'like' number 1000 \o/
🥳😁
This is a beautiful watch and I'm so happy to watch your skilled hands work on it. Be careful with that little brass/nylon hammer. I am so looking forward to my King Seiko arriving soon. It's interesting that the Do Not Open on the barrel is in English. Were these only produced for the export market or domestic?
Hello Clay, thanks so much! This watch is indeed spectacular and I'm thinking of keeping it for my own collection 😎 Most Seikos were produced for export, including this one, but I think they used the English wording as default also for the domestic ones. If anyone out there knows better, please educate me :)
Great video as always.beautiful Seiko and that dail sitting behind the faceted glass just looks gorgeous.think I would personally put on a leather strap or even maybe a nato instead of the mesh bracelet but that's me,never been a fan of mesh bracelets.
I literally just stripped down my first seiko movement ever(nh35a)last week.still waiting for a few things before I can clean movement and go about reassembling/oiling it.havent heard anyone talk about cleaning solutions to use in ultrasonic cleaners for movements so I bought something called Zenith formula 67 watch/clock cleaner along with a final rinse solution from Zenith as well.hoping that'll work out fine for me as a person doing this for a hobby.one thing I was informed to buy for use to clean cap jewels is a cleaner called onedip so I did buy that as well.also the stuff you soaked the pallet with,is that stuff beneficial to use on all pallets for all automatic movements like eta and sellita?you also said that on watches such as this GS that have medallions on the case back can't be put into ultrasonic cleaner because the back will get damaged.why is that and exactly how would the medallion part of case back get damaged in the cleaner?
Looking forward to next video and more education.
Hi Richard, thanks for watching! This watch would look good with any kind of strap or bracelet, I think. I believe it would originally be offered with both a steel bracelet and a leather strap but not a mesh bracelet, indeed.
Nice to hear you're serious about your hobby, it's a great interest that you can do pretty much until you die at the desk :) There are a lot of different cleaning solutions out there and it's a bit like choosing between Pepsi and Coke; they'll all do the job. Just make sure you also have a rinsing solution. You would typically have one cleaning jar and two rinsing jars and run the parts through them in sequence.
Onedip is typically used for hairsprings, although I rarely use it myself. For cleaning the cap jewels you will want a naphtha solution, lighter fluid works well. Fixodrop is what I use for the pallet fork, and I use it on all watches of all kinds. It helps the oil stay on the face of the pallet stones rather than creeping off.
Medallions like the one on the case back of Seiko KS's and GS's are fixed on the outside of the case and if they are subjected to ultrasonic waves they could start loosening. The result of this would be that the medallion would partially come off the case back. So not what you want to see...
@@VintageWatchServices awesome.tyvm for the advice along with the pointers on different types of cleaners and whatnot.guess I could saved a few bucks and just bought lighter fluid for cap jewels instead of the onedip but hey can't learn without asking questions.i do already have a cleaning solution but still have to get the rinse solutions which I will be getting this coming week.
Also so far your the only one I've heard speak of doing any lubrication on the rotor bearing itself.rite now the oils I have are 9010,D-5,8300 natural grease and 8301 grease with graphite.would any of those work well for the rotor bearing like the D-5 or should I get the same stuff that you said you lubed the bearing with.
Again I thank you for all your advice and look forward to next video.take care and stay safe.
Lubrication of the pallet stones is a point of debate. The stones are extremely hard en very resistive to wear. The balance assembly is argually the most sensitive part of the watch. Though lubrication may seem to improve the stability of the watch right after the service, it can and will induce drag and contamination, which shortens the time until the next service.
Hello Berre, for the lever movement, lubrication of pallet stones is not really a point of debate, unless you mean that you can lubricate the escape wheel teeth instead? That is an option but not very common.
There has however been a lot of effort in trying to come up with escapements that do not require lubrication, this was the driving force behind George Daniels' co-axial escapement for instance and later Roger Smith's work.
I almost had buyer's remorse having bought a 1967 Grand Seiko, but now as I see its little shiny heart, I am OK.
How could you not love the beauty of this engineering? It is something I am ready to pay money for.
Am I totally mistaken, or do you have a ring of Scandinavia in your accent, ever so light?
Yeah, GSs are fabulous watches. And yes, I'm Norwegian :)
@@VintageWatchServices Heia Norge!
Hyvää Suomi! :)
Nice 👌🏻
Thanks ✌️
Thanks for getting back with me all. I guess I can be intrepid and wear the watches or mess them up from hand winding them a bit every day to wear them for two hours. Or just leave them in the watch box. I had my Hamilton Khaki manual regulated (a hobbyist or destroyer of watches myself). Played nine holes and beat error went from 0.00 to .1 to . 2 and 0 seconds a day to plus 1 or two. So I guess these are arm chair “field watches”. Guess I will have to keep wearing the 1953 Bulova if I want an automatic to golf with. Sorry to whine so much.
A field watch nowadays is probably about as useful for being in the field as an SUV is for driving off-road... The only thing different with them are basically the dial design. Probably an old Timex is the best for a golf game, they'll take a licking and keep on ticking, I've been told 😁
Could you please make a video about seiko's spring drive movement?
Nope, not a fan
I'm a fan of Seiko watches and I see they use white base metal for almost all their parts. What materials do they use exactly? Great coverage here!!
Hello Stephen, thanks for watching! Most watch brands use plates, bridges and cocks made from brass which is plated to achieve a uniform look and to protect the brass a little bit from oxidation and scrapes. This plating is typically either gold, copper (as in vintage Omegas) or rhodium, as in most modern movements. Rhodium is bright silver colored, and this is what Seiko uses from what I know. Older watches with the same kind of silver look can also be nickel plated, and higher grade old watches and some new one like Lange use German silver, which is a copper/nickel/zinc alloy.
*_Great job!_* *Are the sealed barrels much different inside, compared to a "standard" barrel & mainspring?* What advantage does this provide, a fresh mainspring, fresh lubrication for better performance? It reminds me in looks, of a Rolex 3035 but without teflon coated, coloured reversing wheels.
Hi Joe, thanks for watching and for your question! Sealed barrels are typically no different from normal barrels, apart from being more difficult to open and close, as the lid is typically thicker. The spring and barrel are generally the same. The reason some manufacturers did it this way back in the late 60s and early 70s was to ensure the steady power supply from the mainspring, which can be jeopardized if someone fiddles around with the barrel. They recommended to change the barrel complete with every service. However, as can be seen in this video, an old barrel complete like this one still provides plenty power, so you can often get away with not changing it. But opening it is perilous as it could be difficult to assemble it again.
For this movement I completely agree; this looks much more like a Rolex movement than a standard Seiko. It really is a wonderful movement and very high quality.
@@VintageWatchServices: *_Grazie, l'ho apprezzato!_* 👍🏽
I wonder how similar Super Lube's synthetic grease is to Labelle 106? I sometimes use it to lubricate sliding points in precision measuring instruments.
I cannot say to be honest, I don't know Labelle 106 that much apart from a quick google search just now :) It's not a product I have ever heard of for use in watches, so I wouldn't recommend it.
did you open the main spring barrel?
TOP
👍
Thank you for sharing, I absolutely love your videos, could you please elaborate on why would the ultrasonic damage the case back of the watch?
Hello Mohamed, that's great to hear, thanks! For case backs with an applied medallion like this one, the vibrations of the ultrasonic may lead to the medallion coming loose. For solid casebacks as in the vast majority of watches, it's not a problem to use the ultrasonic.
@@VintageWatchServices Thank you for clarifying :)
My pleasure of course :)
Great to see you working on a Seiko. This GS Hi beat is a grail watch for me. I have a question, I have a Seiko SNXS77 with a 7S26 B movement and it runs very fast because of the balance wheel hair spring seems damaged, can I replace it with a 7S26 A balance cock and wheel? Nice and relaxing as usual and a great job, cheers.
Hi Francis, thanks for watching and for your comment! I haven't worked on the 7S26 series myself, but from what I can see the balance is the same, only the regulator is different. I found this that may be useful: wristsushi.proboards.com/thread/20026/7s26a-7s26b-7s26c
@@VintageWatchServices Thank you very much. Keep the streams coming the are great. Cheers Francis.

Oh please, please, please do my 1975 Seiko Perpetual Calendar. It's my high school graduation gift that a few shops have essentially ruined.
Hello Kenneth, sorry to hear your watch has not been treated well. I assume it's a quartz watch? If there's an issue with a quartz movement it can basically only be replaced by an identical movement. Unfortunately I do not have the equipment to work on quartz, but if you contact Seiko directly they should be able to help you.
@@VintageWatchServices Thanks for your prompt reply. I'm certain it's a self winding movement. The number code on the casing is 7006 6039. I thought it was a mechanical movement.
Ah, okay, thanks for that. Then it's not an actual perpetual calendar, but the one with the 31 calender inner bezel?
@@VintageWatchServices Yes, that's the one. It has a beautiful blue dial and the original stainless strap. It still winds and runs, but not well and not for long.
@@VintageWatchServices I just took it out again and wore it for the day. It gains one 5 minutes every hour! Would you be willing to fix it for me?
an absolute beauty ,the roller winding system looks very reliable compared to some !! even if if I love swiss made ,this is a nice caliber , regarding high beat , I don't care as long as it is a stable time keepr, else my epson YM62 is unbeatble...
Seiko has made a ton of very fine watches indeed, just with a different mindset than the Swiss for most of them. They do make some incredibly high end watches also though, check out Credor, their high end brand.
@@VintageWatchServices yes this is true and is a point where the swiss are making a mistake , but I think they are coming back with schools and french Briancon/Morteaux very good school for watchmaking
slaves or good mechanics ... , missing is engineers to start new era , but with the comeback to mechanical watches , not only for EMI from stupid atomic event , but the real reliability , see stats on the quartz watches , they go to the bin at an average of one cell battery ....but with new engineers ( most movements where designed before 70 years ago ) using modern know how could design ideas for fabulous mechanical wathches ,like using carbon fiber spirals ,magnetic floating balance weel,very light escape weel and anchor to reduce inertia loss ,low beat for less ware , and more...

Did you take any extra precaution on oiling due to the fact of being a 36000 vph? Shall the lubrication be much different from a 28800?
Hi Henrique, thanks for watching! I follow the BHI's recommendation which you can find here: www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwi4id25ht7vAhX68LsIHcbnAO4QFjAAegQIAhAD&url=https%3A%2F%2Ftheindex.nawcc.org%2FArticles%2FBTI-The_Practical_Lubrication_of_Clocks_and_Watches.pdf&usg=AOvVaw0Nlfmcsoljrth5lg8fHEYU
It basically says that for lower beat movements one should use Moebius 941 (or similar) and for high beat movements - 28800 and higher - one should use Moebius 9415. 9415 is a grease, and that is what you saw me applying to this movement. The reasoning behind it is that since the pallet fork moves much faster back and forth and the movement of the balance wheel teeth across the pallet forks is so much faster, the lubrication needs to be thicker in order to stay in place. Hence the grease 9415 instead of the oil 941.
Mr. Bagus jam tangannya. Asli rumus rotasi bumi?
Hi Sir : which part of the watch to make the beats 18000 , 21600 , 36000 ?
Hello Ben, that's a great question! The short answer is the entire train of wheels, but the main component making a watch beat faster is the balance spring. To achieve a high beat rate you need a much more rigid balance spring, as a soft spring simply wouldn't be able to rotate back and forth fast enough. Once you have a rigid enough balance spring, the rest of the wheel train of course has to be calculated with the proper gearing between the wheels and pinions to ensure that the hands rotate at the pace they should. Key to this is to equip the escape wheel with a few more teeth in the high beat movements simply to avoid having wheels and pinions with too many teeth further down the train. The escape wheels in low beat movements have 15 teeth while high beat movements typically have 20 teeth. After that there are a few common ratios being used but it also depends on whether the movement has a cannon pinion on the second wheel or an indirectly driven hour wheel etc.
@@VintageWatchServices Thank you very much Sir !
I have one more question to know , would you kindly to answer me again ?
Hi beats watch escape wheel has 20 teeth then Low beats escape wheel 15 teeth , so does the distance of the pallet fork left stone to right stone also has to be changed to fit the 20 teeth escape wheel ?
My stupid question meaning is : Is it there has the difference distance between high beats and low beats pallet fork's stone to stone ?
Thanks !
Sorry for always bombarding you with questions haha. Found it interesting you said you grease the pallet stones instead of using 9415 on a hi beat. I'm actually about to service an old beautiful ladies seiko hi beat with a 2205 for my mother. What grease would be appropriate for this movement at 28,800 bph?
Hello Nunya, I didn't actually say to grease the pallet stones *instead* of using 9415; 9415 IS the grease I use :) As opposed to 941, which is an oil. 9415 is perfect for 28800 movements.
@@VintageWatchServices Oh ok, i guess it was the characterization of "thick grease" that threw me off. Ok good to know. That's what i use. Thanks again.
Pretty sure I didn't say "thick grease" 😉
Okay, this is great! I have one of these exact watches, so I watched with maximum interest. QUESTION: Where can I purchase a new crystal such as you have done? I have looked with no success. Any help is greatly appreciated. Also, thank you for all the jokes. Also, much appreciated.
Hello John, thanks for watching! I got mine on eBay, actually, and you should be able to find one with a bit of patience :)
@@VintageWatchServices Thx. I’ll keep looking, I’m really excited for this watch. Everyone keeps marveling how patient I am, they don’t recognize I’m merely stubborn.
How do you access the stem release once the dial and hands have been set in order to recase the movement? Simply place it dial down on a soft squishy surface?
Hello Karst, thanks for watching and for your question! I personally don't like putting the dial on anything, so I prefer to put the watch on the bench on the side and hold it steady.
@@VintageWatchServices No thank you for the videos! They are very enjoyable and on top of that immensely helpful. Yes, that method makes sense. I have done it like that as well but it feels like I would need three hands to do it securely sometimes, especially when the dial itself is larger than the movement.
34:10 we can see your nose and beard! If you are not careful your subscribers will capture these moments and build the full picture, just like with Mr. TwoHands from WatchFinder :-)
On a more serious note, that really is a stunning watch with a beautiful dial; a welcome change from a steady Swiss diet.
How uncommon are faceted crystals in reality? I've only seen such once before, on an old Orient automatic I have here somewhere. I always wondered if they were ever common or if they were a one-time fad
Darn it, I always had a hunch it would be a really bad idea to launch a TH-cam channel... there's of course a reason I had to leave Norway. "Just when you think you're out, they pull you back in!"
This really is a beautiful watch, fully agree. It is quite different from the typical GS, both in terms of colors and angles. Looks fantastic on the wrist. Faceted crystals are and were very rare for a few reasons; they are a bit more expensive to make and have more edges that more easily get chipped. A flat or slightly domed crystal is much less prone to getting damaged. But they do look very cool :)
LOL!
Hello Dion and congrats for your videos, i have one question, the mainspring of this watch is not necesary lubricate it? thank you
Hello Mark, thanks for watching! Some of these old watches have barrels that were supposed to be replaced at a service rather than having the mainspring taken out and cleaned. The issue is that the barrels can be very difficult to put together after opening, so if the amplitude is alright I use the old barrel as is. If I have a spare barrel I would try to open this one and lubricate it.
@@VintageWatchServices thanks a lot for your answer, one time i service a Zodiac sst 36000 with this kind of barrels and I managed to open it, the problem was that I couldn't close it later 😅. I'm from Spain(Sevilla) and i dedicate myself to the repair watches since 10 years ago, more or less, i love repair it, and your videos are very instructive. Thank you very much for the information and keep it up.
Oh. By the way. Do you scribe your "Mark" inside the case when you do such a detailed rebuild?
Hello Stephen, thanks for your question! No, I don't and I don't think anyone should do that. It is in my view no less than wilfully damaging a watch and such practice has no place in our day and time. Perhaps it served a purpose 100 years ago, but not today. There have been better ways of tracking who worked on the watch basically since pen and paper were invented (which coincidentally was way before the watch was) 😉
First time GS on watchmaker's bench I saw. What was the reason Not to open main spring case? & Why not a new seal for winding crown stem ? Next time Pl show how regulation is done with Time Grafer. Cheers. & one more thing gear teeh are not lubeed ??.I did enjoy watching Video.
Hello Tissa, no, watch gears are never lubricated. The teeth roll on each other's surfaces, they do not rub. I have some other videos showing how to regulate the watch, you can check this one for instance: th-cam.com/video/3E-L8BamNM0/w-d-xo.html
👍🏴
Seems you're going through all of them! 😎
@@VintageWatchServices I certainly am brother and enjoying myself binge watching best site on the net by a country mile. Keep them coming love everything about vintage watches you should have your own TV show. 👍🏴
Maybe some day! 😂
For the Fix-O-Drop, wouldn't it also be applied to the escape wheel?
Yes, that's best practice. I've changed how I do things a bit over time :)
@@VintageWatchServices Thanks for confirming. What's the purpose of the funny shaped, and rather expensive, epilame bottle? I'm just getting started in this hobby and there's lots to learn.
Great content and good job on this watch. How would you rate this caliber in terms of decoration, reliability and seviceability against e.g. the newer almost grand seiko, but slower beatrate and not regulated 8L35B? Thank you.
Thanks for watching and for your question! I haven't worked on the 8L35, but the decoration level is certainly higher than on this one. For the performance and serviceability I wouldn't really be eligible to compare them but Seiko quality is very, very high in general, really focusing on functional requirements more than non-functional.
I like your tweezers are they custom or can we all own a pair?
They're from Regine Horology, and Horotec sells some quite similar, just with a straight angle instead of a curved one.
Can you reasonably safely play golf with a modern Seiko or Hamilton watch. I have played with a 25 year old Seiko 5, a 60 year old Bulova , two 60 year old Elgin automatic watches and a 1960 Hamilton K 416 with the Hamilton 661 (read Certina) movement for years not even thinking about it. But my Seiko Sarb 033 with the 6r15D and Hamilton Khaki automatic with the H10 2824-2 mod states in the manual that you shouldn't play golf or tennis with them. So since I work in utilities I am not going to beat my best watches up there I wear a Timex or 15 year old Seiko Solar. Therefore the only time I can safely wear the new Hamilton and Seiko is watching your videos before I go to bed.
I have a 15 years young 6R15A which has seen the links and shooting range more than a few times. Serviced once by Seiko, she runs at -1/+1 per day, as long as she rests crown down overnight (slows down the average +2 daytime gain on the wrist). The rapid date stopped functioning a year ago, when the crown is pulled out 1 click. The watch keeps running, the crown has no effect, but the date advance overnight otherwise works normally. It hacks and the hands turn normally to set the time at position 2. Pushed in at position 0 it winds normally by hand also. No other problems have developed. I don't often wind it by hand, the automatic rotor system is efficient.
Hi Jeff, thanks for watching and for your question! Sports can be quite tough on watches, especially if you wear the watch on the wrist that is closest to the action. Manufacturers' advice is though always based on worst case; e.g "don't play tennis with your watch" assumes that you're hitting very hard and generate a lot of force in the action, but the truth is that most of us have tennis skills that probably rival Howard the Duck's rather than Roger Federer's. So we're probably safe, but I still take my watch off when doing sports(chess and curling should be fine, however).
Nice intro :-D
Thanks 😁 Better, right?
@@VintageWatchServices jes its nice xD
@@theo5413 I saw your 7734 video, btw, very nice camera work!
@@VintageWatchServices Thanks :-)
Do you use brass tweezers to avoid scratching the movement? Or for non-magnetic or both? or?
Hello Pat, yes and yes, and also because brass is a bit softer than steel, thus allowing for a little bit better grip.
What is the possibility for damage to the gold medallion on the case back in the ultrasonic cleaner?
Hello Pat, there is a great risk of damage, so I wouldn't put the case back into the ultrasonic. Given that the gold medallion is applied to the steel case, it will start coming loose after just a few minutes in the ultrasonic.
I have heard a lot of watch aficianados say this high beat movements beat themselves to death. That being said, time runs at a constant so the gear train shouldn't really have an issue.
From your experience, does the related escapement parts that are providing a 5Hz beat rate undergo significant wear due to the higher beat rate?
Is it more important to service these on a regular interval?
Thanks....just subscribed.
Hello Mark, thanks for subscribing and for your question! It is indeed just a few parts that have higher direct wear due to faster rotation, and the exact reasons for most manufacturers backing off of 36000 I think is more due to 28800 being fast enough... Nowadays in particular, watches aren't really made to last more than a few years, and with a higher beat rate the need for lubrication is higher. But any exact experiments or results from 36000 watches is very hard to find.
Sir, do you have a recorded version of all your vintage watches restoration? Either in a pendrive or in a CD. If yes, I am prepared to buy it. You have to let me know the cost. Please revert on this. Thanks and STAY SAFE.
Hello, thanks for watching and for your question! No, I unfortunately do not have the recordings in such a format. If you need to download them rather than stream from TH-cam, I believe there are some apps that allows you to download videos.
#171 thumbs up
Thanks, Steve!
What is magic about the magic lever?
Nothing, really 😁 It's just a nickname, but it is a piece of brilliant engineering for sure. museum.seiko.co.jp/en/knowledge/trivia04/
Interesting video. Referring to the company as Psycho seems a bit harsh but I know they've annoyed some collectors in recent years so I won't leap to their defense!
I'm not actually saying Psycho, I'm saying Say-ko, but think of the "Say" as how Australians would pronounce it 😉
@@VintageWatchServices Oh, heavens! I said it partly in jest but TBH, I didn't pick up on the accent.
You always comment about how expensive that one glass item is. To my untrained eye, looks like it would be an easy enough adventure into glass blowing to make a small neck in the middle of an existing jar.
Well, you would certainly have a revenue source if you can make those jars for cheap!
That movement is equal to a Rolex.
Absolutely!
I wanted to know what them things on your finger are called and where i can buy them, my husband can use these things and i can stop taken these pills.
😂
“Similar to Rolex”….. and just as good and more reliable.
👍 I'd rather have this in my collection than a standard Rolex any day.
Have you ever striped a screw thank you
Hello Mike, thanks for watching and for your question! Yes, I most certainly have stripped screw heads and also broken screws inside bridges, mainplates and barrel arbors. I've also broken pivots, messed up hairsprings and put the mainspring in the wrong way as well as scratching dials and cases 😂 Luckily quite a few (but not all) of these things were done on watches I bought for practice :)
It's all part of the learning process I think. It's been quite a while since that has happened, but especially when you're just starting out it can be difficult to know how much force to use, how important it is that screwdrivers are fit for the screws etc.
@@VintageWatchServices Thank you for your answer I ask this question because it seem pretty easy to do so I guess it is a learning curve thank you
1:43 jesus...you buy new releases with those timegraph specs
Wrong balance wheel lift angle! Correct angle is 52,4°(52,36°)......
Hello Orlin, thanks for watching and I hope that little mistake didn't wreck the whole experience for you! 😂
If you know the actual lift angle you probably also know that it's not a big issue to use a slightly different lift angle if the amplitude is within healthy limits. If the amplitude shown in the video was 230 degrees it would be important, but in this case a 52.4 degree angle would probably lower the amplitude to just below 300, which is still very good for a Seiko this age :)
I bet that NOS crystal cost as much as many entire watches cost.
I think it was about $50, so not too bad but certainly a lot more than what you would get them for when the watch was still in production...
Please message me for where to ship that watch. Thanks! Maybe a drawing? :)
Hello Bart, thanks for watching! I'm not sure what you mean?
You started off with the timegrapher, mentioning how it could do better than the 15 seconds a day it was at. But then you never put the rebuilt watch back on there to show the improvement....
Thanks for watching and for your comment! Sorry if I forgot to show that, there's a lot of editing to do with these videos and sometimes I forget parts of it. You'll just have to trust me that it runs very well 😉
Elle n ya pas grande différence entre 6145 et 6119 presques toutes les pièces de rechanges sont valables pour la 6119
12:00 Always use gloves when removing dna! Ewwwww...
