Adam, firstly a huge thanks for the shout out, you didn’t have to but it’s appreciated. Also this is the best 6139 video I’ve seen, I thought I knew all I needs to know on this movement but your proved otherwise so I will be implementing some of the things I’ve learnt. I will send you an email as I also have a few questions. Great work on one of my all time favourite watches
1:11:37 Just to help clarify any confusion for anyone looking for Mike Bolton’s channel, it is My Retro Watches (not My Vintage Wacthes, as mentioned). It’s an easy mistake in the flurry of producing these videos. I have a fledgling channel myself and I’m sure I have done worse. Still, this is great video. Keep up the good work, Adam and may next year bring you more success. Maybe one day you and I can collaborate on a challenge video of some sort.
Thanks for a great holiday video, Adam! While I do find your videos relaxing, I also find them informative and fascinating. Watchmaking is a hobby I wish I had started when my eyes and hands could do it, but I get to enjoy the hobby vicariously through your videos, and those of a few others. I appreciate the depth of detail you go into, as well as explaining not only the "why and how" but, in many cases, the history. Thanks for all you do!
Your sonic cleaner sounds so much better than mine!...LOL All things being equal, I would keep this one and find another one to sell from your collection. This is a pretty special watch. Great video! Thank you for sharing!
Again fantastic work you done on that watch. Amazing how watch can be a stopwatch and date function. Thank you Adam for all your videos this year, happy holiday and New Year.
What a cool watch! I just love those old Seikos. I have a small watch collection , but my 7005 is still one of my favorites. Gets a lot of wrist time and numerous compliments. Just wish it was automatic winding.
I'm a watch fan and have a few watches. besides changing bands and batteries when needed i don't repair or service watches. I love all things mechanical and love learning about them. but I do watch your videos to relax haha. and learn :)
Great work Adam. Wishing you all the best for the festive season and 2025. Regards from New Zealand 🇳🇿 P.S what is the part number for the mainspring that you did use.
I have a 1969, "proof" (with notch) 6239-6000 version of this watch that I keep on a black leather band, just like Jackie Stewart's teammate, François Cevert, (1944-1973) The "Prince of Formula One" with one GP win and 13 podiums! There is at least one photo of him wearing it in his Ford/Tyrrell.
I applaud you for doing this mainspring swap, but what is the delta on the loss in power reserve. I am sure there are tradeoffs here using this more robust spring. Nice to know we have some alternatives on the spring front. Merry Christmas and Happy New Year.
I forgot to put it in the voiceover, but in the final timegrapher shot at the end of the video showing the watch after it had ran for several days, I inserted some text boxes showing the power reserve test results. My test showed the power reserve at 35 hours and 21 minutes. This watch saw a 8-9 second delta - with about 24 hours of run time on the mainspring. Merry Christmas and Happy New Year to you as well.
That was pretty great. One quibble though, it's one index and multiple indices. The punishment for getting the singular wrong can be quite severe in some jurisdictions. 😉
Hi Adam. Very interesting video. I’m currently servicing a 6139-7070 chronograph. Do you have the mainspring dimensions for the one you used for your upgrade? I’m very interested in seeing if this works for me too. Gaz.
That was the first watch I ever bought, and started my watch-collecting hobby (addiction). I was 14 and the price was $95. That was in 19 Blah de Blah.
I’ve been trying to find that orange Seko that you did that the lead singer from The Who I think you said wore it, if I have the right band, I would love to have one of those service by you and wear it every day
@@WeekendWatchRepair I see! But now, I am wondering how much the worth ofthis watch has increased after your serving! Iguess it's more then $2000, now, isn't it? Especially as this is a very rare version, as we have learned from you!
It may sound stupid but I'd like to know how you take off the crown once you have installed the hands, because the holder touches the hands if you put it dial down.
With my left hand I grab the caliber with dial and hand installed, with my right hand I tear off the crown...the question was: how do you press the set lever? I tried managing the tweezers with my mouth but it's not comfortable at all.
the thing that makes me a bit confused is the price betwen the 6139-8020 "retro-racer", the bruce lee, the darth vader, and the pogue, they all share the same movement and only the case is the difference betwen them... my father bought his 6139-8020 in Macao during the colonial Portuguese wars, I was fortunate enough to find a watchmaker that repaired it to fully function order, however that cluch of the second wheel to reset at 12h is according to him was a pain to set properly, and it doesn't do all the time... the other thing I constantly ear about is keeping the chronograph function working all the time, and I also heard the oposite... so that even confuses me more...
For a Seiko style chrono it's the act of resetting that puts the major stress on the chronograph wheel (and the further the hand moves the more stress there is), so you can choose to run the chrono all the time, or leave it off all the time just don't keep stopping and resetting it, and when you do need to reset it, let the second hand run on to just past the 12 o'clock position (ie 1-5 seconds) then stop and reset it from there
Well, I had to get out of bed at 1am to check my watch... sure enough it has the notch and resist dial. Would need a magnifier to verify 2 piece hand.... got it as gift for 16th birthday, even back then obsessed with watches... So it's rare? Had it serviced once, hard to find someone qualified on that movement. I used a reference from watchuseek forum. Eventually it had troubke running again and I retired it... I knew it was at least a classic... but rare? Woohoo...

Thanks Mike! Sorry for botching the name of your channel in my voiceover, lol. I'll keep an eye out for that email.
@ that’s not a problem pal. I never liked the name of my channel anyway 😂
@@MyRetroWatches HAHA!!!
You and Marshall are responsible for me and my new hobby. Thank you for all your knowledge you put out there for people like me.
I'll take that as a compliment, as you are putting me in with good company. Thanks a bunch.

Thanks. I caught that mistake as well after I posted it.
Phenomenal outcome, Adam! I always learn a lot when I watch your videos. Kudos! 😁
Thank you very much, I appreciate it.
When it comes to Seiko you can’t get more authentic than a misaligned bezel 😂. Really, really great job on this 6139 ‘Cevert’ 👍.
They are not stupid about that and certainly they have a mass production and overlook that very simple problem that we can fix if we a knowledge..
I love when you do a jewel upgrade! I appreciate your level of detail. Keep up the great work!
Merry Christmas. Great video as always!
I really enjoyed this video, Adam. Well done, and thank you.

Great new video Adam, lots of fabulous detail, lighting and video is A1, beautiful watch, hope you have a great Christmas...🎄🎅👍
Excellent result for the hard work, exceptional vid for description & information, brilliant!
Seikos have a different charm. Love 'em ❤
Merry Merry! Great year of content Adam. Looking forward to a big ‘25 for you!
Thank you very much.
Great job on the watch. It looks amazing. An interesting experiment with the mainspring. Great numbers on the timegrapher. Thanks for the video Adam
Your sonic cleaner sounds so much better than mine!...LOL All things being equal, I would keep this one and find another one to sell from your collection. This is a pretty special watch. Great video! Thank you for sharing!
Nice work Adam, love the detail it goes into
Thanks for the video and Merry Christmas Adam
Nice skilled work throughout. 😊
Love your videos. I wear a Seiko automatic as a daily watch you really can't beat them for value.
The pivot montage is a welcomed new feature. Especially with the Ken Burns effects on each photo.
Thanks. I was just messing around and thought it looked pretty cool. I'm glad you liked it.
I'm glad you show details and steps as i am buying tools to try this myself as an amateur.
Again fantastic work you done on that watch. Amazing how watch can be a stopwatch and date function. Thank you Adam for all your videos this year, happy holiday and New Year.
It's a beauty!
Great content Adam 😊
Wow that’s impressive
What a cool watch! I just love those old Seikos. I have a small watch collection , but my 7005 is still one of my favorites. Gets a lot of wrist time and numerous compliments. Just wish it was automatic winding.
Keep it! Merry Christmas to you!
Great Job! Greetings from Croatia.
Great last watch for the year! Thanks, Adam!
Thank you too.
I'm a watch fan and have a few watches. besides changing bands and batteries when needed i don't repair or service watches. I love all things mechanical and love learning about them. but I do watch your videos to relax haha. and learn :)
I have one of these I purchased from Spencer that he serviced. It's an awesome vintage watch. I'd part with mine for the right price.
i think if you sell that one you will come to regret it. Beautiful work as always.
There are several I regret selling, haha, but it all goes back into the channel.
I just serviced a notch JDM speed timer and it runs so incredibly well. Insanely great watches. Thanks for the amazing year of content!
Thanks. They are indeed great watches.
Hot Rod Seiko!
Keep it! Sell some of the watches that are not special to you. You won't find another like this.
You made that second hand fitting real simple and it's truly not! Love your videos
Merry Christmas Adam! 🎄🎅
Have one at home, June 70. Cheers.

Haha
That has to be one of the earliest Resist dials ever. March 1970 is crazy early I think.
Yes, it is very early in the 'Resist' transition.
Hi Adam, that's an incredible result on the timegrapher. Can i ask you please to share the GR code for the mainspring used? Thank you, merry xmas!
I you want to email me at WeekendWatchRepair@gmail.com I can send you the details on that spring. Thanks.
Great vid.
Speaking of tweezers, where did you get your brass curved ones? Elusive little creatures. My supply houses don't have em.
Great video and fantastic results. I am curious as to which main spring you used. I have tried the GR2534X/41X with good results
I’ve used those in the past, but this one was a different part I was trying for the first time.
Hi Adam. Very interesting video. I’m currently servicing a 6139-7070 chronograph. Do you have the mainspring dimensions for the one you used for your upgrade?
I’m very interested in seeing if this works for me too.
Gaz.
I you want to email me at WeekendWatchRepair@gmail.com I can send you the details on that spring. Thanks.
so hard to find a complete notched case 6139.
I’d keep it!
Adam, I purchased this same watch on the ship I was on over in the south china seas
That was the first watch I ever bought, and started my watch-collecting hobby (addiction). I was 14 and the price was $95. That was in 19 Blah de Blah.
I’ve been trying to find that orange Seko that you did that the lead singer from The Who I think you said wore it, if I have the right band, I would love to have one of those service by you and wear it every day
How on earth could a watch consisting of that many parts even be so cheep back then???
That's about $750 in today's money. Still a good deal for a reliable mechanical chronograph.
@@WeekendWatchRepair I see! But now, I am wondering how much the worth ofthis watch has increased after your serving! Iguess it's more then $2000, now, isn't it? Especially as this is a very rare version, as we have learned from you!
@@RalonsoF1 No way this watch should anywhere near $2000! If it is, than I am seriously undervaluing my collection, lol.
@WeekendWatchRepair haha 😂👍🥂
Do you use Bergeon ergonomic oilers? If thats the case, which colors do you recommend? Thank you
It may sound stupid but I'd like to know how you take off the crown once you have installed the hands, because the holder touches the hands if you put it dial down.
I just grab the movement by the sides to remove the crown. I don't use a holder for that particular step.
With my left hand I grab the caliber with dial and hand installed, with my right hand I tear off the crown...the question was: how do you press the set lever? I tried managing the tweezers with my mouth but it's not comfortable at all.
My Retro Watches
Yeah, I caught my mistake as well, haha.
Could be graphite powder in the mainspring barrel.
Very likely.
Face reveal!!! 😲
😄

I wouldn't say super relaxing. You talk at a high beat rate. Like Marshall Sutcliffe after 5 coffees.
