Watch Grand Seiko Master Watchmaker, Mr. Shun Murayama, assemble a Seiko Spring-Drive Movement at Little Treasury Jewelers, October 21, 2015. The context is a watch event celebrating Grand Seiko, hence the background chatter. This is just a demonstration movement, so don't worry, it won't be inside anyone's timepiece.

That clown in the background who tried to challenge the GS master watch-maker by saying that Bulova made a sweeping hand quartz is misinformed. That UHF ticks at 16 bps.
The Precisionist line of Bulova, which is quartz, does indeed have a sweeping secong hand. I believe its the only quartz movement that offers that!
@@lucgeoffrion1970 The difference is in the definition of "sweeping". The GS definition of sweeping is in the most literal sense, in that the second hand sweep is stepless.
The sweeping hand of the Bulova might look like it is smooth and stepless, with no stops and starts, but it does indeed stop and start, just so frequently that it gives the appearance of being steplessly smooth.
In contrast to Spring Drive, which is sweeping in the most literal sense, steplessly with no stops and starts, at all. The second hand in Spring Drive watches is being speed regulated 8 times per second, but never actually stops and starts to do so. The movement is constant.
The guy in the background attempting to correct the GS master watchmaker, was in fact absolutely wrong, because he was disputing the point that quartz watches are stepped in their movement. He wrong.
Yup, what a bozo !
The interaction sort of starts at 6:02 in the video btw.
@@lucgeoffrion1970 Incorrect. The movement you're talking about from Bulova ticks at 16 bps but it still ticks. Grand Seiko's Spring Drive is the only movement with a truly sweeping seconds hand with no start/stops.
Absolutely one of the most amazing movements, it’s also the most profound innovation in watchmaking in the last hundred years
I'm blessed to have the 9F and the spring drive both amazing movements
The workmanship that goes into this watch, incredible!
A true technical marvel of mankind, the essence of Micro Mechanical Wonder.
A lifetime watch that highlights generations of skill.
A master works on a masterpiece
Watchmakers are truly brilliant and talented people.
Very true...and patient!
Replace the audio with technical narration and edit out the time gaps and you’d have an excellent look into a modern masterpiece of watchmaking.
Thank you for the suggestion. If time allows we may do that.
I describe it as electromagnetic braking to lash down the gears and the escapement of power and regulation is controlled by how much power is asked from that braking.
Pretty accurate description...there is no mechanical braking, just an added load to the 'generator'
rolex???? it's just a brand name but accuracy goes to seiko GS period....... eat your heart out swiss cheese lol......
MrZep420 100% true
@bisquitnspanky seiko and seiko, not seiko and GS. the difference in accuracy is big
non spring drive GS movement only guarantees -3/+5 accuracy per day while Rolex -2/+2 per day.... so?
@@neodelphi Having tested a lot of watches on timegraphers, I did notice several things.
While brand new submariners amazingly get consistent readings of - 1 to 0 and occasional +1 s/d readings on all positions, all the older submariners (2-3 year old watches) deviate heavily at anti-complementary angles by some going as high as +4 seconds. While rolexes have very accurate movements and their internal superlative standards are true, it is not uncommon to have to regulate and readjust them again after years of wearing. I’ve yet to find a 9S calibre of any age that deviated more than +/ - 3 s/d.
Take this with a grain of salt though since the sample size is not great enough to form actual conclusions.
But…The thing about Seiko and Grand Seiko is that they perform way better than what’s on the sheet tables. Don’t forget. The 9S is a 36000 bph movement. One of the most accurate movements where only a few other watch brands like Zenith have mastered. 10 beat movements have a much sturdier hairspring where amplitudes are much less affected by external factors leaving less room for error, giving greater accuracy than 8 and 6 beat movements.
@@darkcggaming No, they don't. Some samples might *_achieve_* that, but Grand Seiko do not guarantee that.
Please provide a GS model number where they guarantee +/- 1 spd!
Very interesting, what a fantastic innovation, fully automatic and regulated by quartz, not as accurate as a full quartz movement, but more accurate than a traditionall mechanically regulated automatic.
There is no reason for it to be less accurate than a 'quartz' movement, as long as it stays fully-wound; the control system only requires that the wheel guarantees to be #able to rotate faster... as long as that condition is met, the control system should be capable of perfect synchrony with the quartz crystal frequency.
More accurate
@@tellucas + or - 15 seconds per month for a Quartz watch is incredibly bad, even a $200 Quartz watch should be +15-15 per YEAR
@@ApotheNZ Agreed, from what i can tell quartz technology for mass produced movements has pretty much been at a standstill for the last 30-40 years. Even Timex should be a few seconds a year by now
I keep hearing this that it's not as accurate as traditional quartz but it's just not true. My GS Snowflake runs more accurate than any of my wall clocks, my G-Shock, and my Citizen Eco-drive.
It would take too much energy to make a traditional battery powered quartz watch rotate smoothly. The accutron or whatever, it ticks, just at way more vph. It looks smooth but it's actually ticking. The spring drive is totally smooth. I think it's the brake that regulates everything and allows for a smooth second hand.
The main spring powers a tiny generator that applies a charge to a quartz crystal and a tiny Integrated circuit which checks the oscillation of the quarts crystal against the second hand position 8 times a second.. It then applies or releases a magnetic brake. It's like setting the cruise control on your car and then just using the brake to maintain a constant speed. It doesn't tick because there is no escapement unwinding the main spring a beat at a time. It is constantly unwinding. Just to expand on what you said😁
@@Surfingolas1 you sound like you know what you are talking about and I have a question, I am believing that these spring drives have a rotor in them and if so does that help wind the main spring or is it only wound up manually every 70 hrs or so, guess I will find out myself in the next week or so when my Marinemaster arrives, asking because I cant seem to find any info that details anything about the rotor.
@@winstonsharpe4080 I don't own one but I am fascinated by them so cheers to you for taking the plunge. I believe in that respect it is a traditional automatic watch. The movement of your wrist turns a rotor which winds the main spring. It is the energy produced by the unwinding of the main spring that powers the IC and the quarts oscillation.
@@Surfingolas1 Thanks for your reply, yes , I have become fascinated with the spring drive also, I am looking for a few things from a watch, accuracy and weight are the two main ones and the Marinemaster looks like it is going to give both. I have been wearing a Tissot T touch Solar Expert for about 6 years now but it is playing up, the lightest watch I've ever worn being Titanium and the most accurate being quartz, only ever adjusted the time changing for daylight saving but I dont want another watch with a lot of electronics and settings so hoping the spring drive will be a fairly simplistic timepiece and I guess with owning one it shouldn't be that hard to work it out, I am like a lil kid waiting for Santa to arrive xmas morning hanging out till it arrives haha!
@@winstonsharpe4080 yeah you can't get more accurate than a quartz watch because of the law of averages. The more oscillations the more accurate a watch is. A quartz crystal oscillates at like 32800 hz. Even the most high end mechanical watches oscillate at 10 hz. So a $10 quartz watch is more accurate than a 30k Rolex. That's why the spring drive is an awesome movement. You get the accuracy of quartz with the charm and craftsmanship of mechanical with a true sweeping second hand.
lt would have been perfect if they explained each part, what it does , a liitle about manufacturing etc instead of people rambling on in the back ground .
He never had a chance... the Japanese people are somewhat reserved, so you need to let them open up for them to really start communicating. Those pretentious customers commenting in the background basically took over the conversation, which I'm sure hindered this guy's work trying to... you know... put together a state of the art movement while they kept blabbering about Fairfax and whatnot.
your data24 obnoxious commenters made me cringe every time they opened their mouths, so embarrassing
your data24 , now I like Americans but they do like to hear themselves talk.
8 times per second is the rate at which control over the wheel speed is computed, and it is related to the same kind of crystal fewquency as a 'quartz' watch, but the combination of the energy delivered to the coils to power the electronics, and an 'extra' load that is applied that can slow the 'generator' wheel, is determined 8 times per second...probably a 'frequency-locked' and 'phase-locked-loop' control system.
sounrds right.
72*60*60 = 259200
259200/8 = 32400
which is frequency of the quartz (gs may have their own quartz crystal that vibrates at a different rate as usual quartzes)
Best movement ever
wow and now we know why some watches cost more than a house
I don't know about this particular one, but GS goes for about $6K, so not quite a house.
GS is actually the best value in watchmaking bar none. You’re basically getting Patek quality for 5k
The best finger rubbers I've seen. Anyone know where I can get them!!
Karin Lefevre go to your medical supply house...
Finger cotts
In my kitchen is a 1945 Telechron clock that uses a mains powered synchronous motor to achieve atomic clock precision timekeeping. Bought from eBay for $30 USD. The Grand Seiko is more portable, but for a premium price.
無駄がない動きは凄いです！
尊敬しかありません^_^
Steady hand and perfect eyesite required to complete any watch build... These are truly stunning watches.. A match for any of the "top class brands"
I had expected he'd have a tiny torque indicating screwdriver but I imagine after all this time he's probably accurate to a few gram/centimetres.
A real watch maker has a torque indicator implemented in his hand
The greatest innovation in mainspring-powered watches since the original Bulova Accutron tuning-fork regulator!
This seems very similar to the Tissot electronic drive that also had a constant sweep second hand. I had one that I was given by my uncle that he bought in the early seventies. Unfortunately the coils are now broken so I doubt it can be repaired.
There is no similarity there. The Tissot electronics are based on the tuning fork first brought to market by Bulova. A battery is required for this. The clocks do not have high accuracy because the tuning fork only oscillates at 300 Hz and not the 32768 Hz of a quartz. Of course, the pointer wasn't really sweeping either. It was driven purely mechanically by the tuning fork in 300 partial steps.
Beautiful craftsmanship. I wish I could own one in a diver. lol
You can - search "MARINE MASTER PROFESSIONAL 600M REF. SBDB011" and you will find your watch.
@@SilencedMi5 Yes, you are so right, I have found my watch, should have my SBDB011J in the next few days and cant wait to get my hands on a piece of art, lol, cant afford a GS and never would want to spend 10k on a a watch but for under half the price I will have something just as good, glad I finally discovered the Seiko spring drive Marinemaster Professional 600!!
No one knows when a wish will be granted. Dreams do come true,put your heart into it...
I watched in awe at this master at work
Brilliant competent work. What make are those screwdrivers?
Indeed! Most likely Bergeon, but this was years ago so no way of knowing exactly.
I'm a fan of the technology but there's a few things stopping me. As it stands nobody still knows the true longevity of Spring Drives as the oldest SDs are still only less than 50 years old. There's a question about the future availability of ICs and that they have to be serviced exclusively by SEIKO.
A A don't worry China clones Ics very cheap !
Longevity wise it's designed to be repaired so as long as they make parts it will be easily serviced by them.
There's always a risk that a manufacturer may go out of business but considering how big seiko is and how long they've been around they're about as likely to go bust as rolex is. Of note is that rolex only services up to 30 years whilst the spring drive has been pledged to be serviceable for at least 40 years.
You’re not an early adopter!
GS, is a chronograph style, upper plate meas chronograph style.
Titus tuning fork watches are the perfect alternatives to costly spring drive . We get smooth sweeping in a very low budget
But those take a battery right? Might as well have a quartz movement then. The spring drive doesn't need a battery
There is no similarity there. A tuning fork watch needs a battery. The watches do not have high accuracy because the tuning fork only oscillates at 300 Hz and not the 32768 Hz of a quartz. Of course, the pointer wasn't really sweeping either. It was driven purely mechanically by the tuning fork in 300 partial steps.
I am in love
thank very much
It's interesting to see how he uses his fingers to hold the backplate. I also interesting to see that he looks like he hates dial feet screws as much as I do haha
It conquered what they claim as chronometer! This is the real one! Is it patented?!
Grand Seiko is a Soul of all the Watch! Seiko I love you!
Thank you for your reply
Everything as always - one works, and four bark under his arm, not understanding anything in what is happening, and prevent this one from working normally.
Amazing
loved the video.
A cheap battery powered quartz clock has a sweep second hand, but it goes through batteries like crazy, or needs a plug.
Indeed it does!
Why is that guy asking them questions when he can see that he's trying to make a video vary rude
I would imagine that the fellow with the irritating voice in the background is all grown up by now. I opted for reducing volume to zero.
I've got to buy me one
spring drive has soul and heart like true mechanical watches ? I don't know what to think.. and how do you think ?
Michal844 , Cool as hell Hybrid.
This watchmaker is incorrect. The Precisionist movement by Bulova, which is quartz, has a sweep seconds hand and the battery on my Precisionist lasts two years or more. It's also highly accurate to a second or two per month. The difference is that it's battery powered versus the Spring Drive which is mechanically powered.
The watchmaker is 100% correct. His definition of a sweeping hand, which is the most literal definition, is that it should be stepless.
The Bulova sweeping hand is not stepless, while the Spring Drive sweeping hand is.
Watch enthusiasts refer to a second hand being sweeping because they *_appear_* smooth, but rarely are they actually perfectly smooth.
I love it but realistically I’m going to stay with my Kinetic. Would like a perpetual calendar though.
So what makes a kinetic realistically better than this? Is it a price thing?
@@GThelljumper091 I never said it was “better”. Though in absolute terms, kinetic watches have a bigger power reserve.
those customers sound incredibly pretentious, its annoying and its literally making me cringe to the point if nausea. keep up the good work though, that doesn’t look easy.
Claiming that a recording of someone else's pretentiousness made you cringe to the point of nausea.....
nomercy315 I just posted this almost identical comment before reading this, makes my skin crawl
Can you purchase just the spring drive movements ?
cannot do not get a journal has a breaking break and even even both the same nunk of the clock of the clock does not waiting this time, it is 1 application but simple complex is the conversion by the power variable from the power to the power on the roto and stato, it is the speed by the gum, do you like to the specified 1 line of the power in the strings of the line strings to create 1 by balance by the clock clock to each seconds .
That is a thicc movement. No wonder all GS's are so large. BTW, why did you assume when the man said he was moving down south that he meant Miami?
PS My first GS Spring Drive arrives in a few days.
Shame about all the background chatter , phones doors etc
Can you service GS anywhere in Europe?
I'm not sure where the GS service location in Europe would be, but if you purchase the GS from us you will have an International warranty.
Sieko Grand Spring Drive is a soul of all watch in Japan., the great watches GS.
thx for the upload :)
Thank you @lefty1999. We are planning another Grand Seiko craftsman event in our store on June 22. Please check our website www.littletreasury.com for time and particulars. We will take another video and post.
good deal, thanks again
I hope this isn't going back into a sale item..
Not at all. This was just a watchmaker demonstration at an in-store event.
Now we know why it's worth thousands of USD.
The 8 samples per second has nothing to do with the timekeeping function. You just see that statistic and your traditional way of thinking about a mechanical watch kicks in I guess.
It reminds me howl's moving castle.
No oiling?
This is just a demonstration movement that gets disassembled and assembled to show the process. It will never be live in a watch.
What a Dreamjob
Here is my suggestion, let me assemble the whole watch and sell me at a cheaper price. Save the labor cost and I can get it for cheaper plus enjoy assembling the watch.
Better yet, let us send you the CAD file and you can 3-D print it and assemble it as well for almost nothing!
@@littletreasuryjewelers1839 Please do.
Good luck with that. Not sure you can 3D print those coils or magnets
可也 複雑でした。
I heard japanese, american, and hongkong speaking in english
Yes, this was a demonstration in our store in Maryland, and a number of people of various nationalities were present.
Seiko was rude to me, bad customer service.
Love the finger condoms
let's see if Chinese will replicate this Technology , good luck Chinese
I think they will ,they already made the GS diver watch on sale around 350usd
Lubrication?????
This is a demonstration in the store. That particular movement is used just for that purpose and has probably been assembled and disassembled dozens of times. Movements used in finished watches for sale are definitely lubricated.
He sprays the whole thing with WD40 when he’s finished 😀😀
SEIKO NO BRASIL NAO PRESTA, PESSIMA QUALIDADE.
Tá doido! Compra um “SEIKO 5” pra você ver se não presta! Mas vai pagar uns 700 Reais. Compra um “SEIKO Presage” pra ver se não presta! Mas vai ter que pagar 4000 Reais pra isso!
Depende de qual SEIKO. Tem pra todos os gostos.
Esse aí, o GRAND SEIKO, também vende no Brasil. É só você pagar 15 mil reais!
who asked..is this from the back? such a stupid question.... wow
You guys just f...d the video by talking in background. Ridiculous!!!!
Why is he wearing condoms on his fingers ?
PeterPiper Chaos finger cots, they're used for medical purposes as well as to keep the oil off the movement
PeterPiper Chaos to make sure no baby parts are made during the assembly
To keep salt off the components to reduce oxidisation.
$70,000.00 Watch USED
Spring Drive watches can be bought new for less than $6000. The most popular Spring Drive Grand Seiko, Snowflake, is $5800 and it's a damn beautiful watch. The ones that go for five figures are usually limited edition really fancy looking watches like with diamonds in them.
This one looks like a chronometer which is a bit pricier than the day/date only movement of the Snowflake and could go into the $10-20k range but nowhere close to $70,000.
Annoyingly too much ideal chatter
Waste of time
So is your comment. And it's "idle", not ideal. Uneducated dumbass.

Sorry spell check changed on my phone, but not uneducated retired clinical pharmacist
Again waste of time no educational value
I love Seiko watches but there’s no way I’m going to pay $5,000+ for a Quartz watch. I’ll keep my 6105,thank you.
lol. Did you not watch the video? The movement is way far from a "quartz" movement.
@@jaad9848 don’t worry about it. Usual snobbery :)
LOL Spring Drive is not a "quartz watch"!
Quartz watch = quartz timing is used to *_ADVANCE_* the movement.
Spring Drive = quartz timing is used to *_REGULATE_* the unwinding of a traditional mechanical movement.
These are *_RADICALLY_* different concepts.
The Spring Drive provides a completely stepless smooth sweeping second hand, from an otherwise regular mechanical watch, with quartz accuracy, yet no battery or capacitor and with no torque jarring stops and starts, whilst using a completely frictionless electromagnetic brake on the glide wheel (which replaces the escapement).
*_RADICALLY_* different concepts! To refer to Spring Drive as a, "quartz watch", is to demonstrate that you have no clue what you're talking about.
As a video its real garbage, tells and shows nothing.
Piece of crap , I buy one of these ,break 3 time ,
whoever buys THIS watch will have to take it to a REPUTABLE servie center and have it oiled and greased. not ONE single pivot point was oiled, and NO grease was applied. shame. :'(
Michael Ponomareff
Dude this was NOT a repair Job but a DEMONSTRATION!
lol
Christopher Jefferson he just wanted us to know that he knows that oil and grease are used in watches
Michael Ponomareff - my 2005 Spring Drive SNR005 has been working flawlessly going 13th year without ever being serviced. Accuracy is still like new within 1 SECONDS/WEEK. My Official Certified Chronometer watch gains 5 SECONDS a DAY. Reserved power is exactly 72 hours which is far better than 42 hours of my Official Certified Chronometer watch.
After having all kinds of watches over half a century, the Spring Drive is the most satisfied and the best watch technology because of its unparalleled performance in all areas: accuracy, precision, long reserved hours, absolutely quiet gliding second hand like time flows. the dependability of telling time accurately and it even works after 3 days off wrist (Weekends) or whatever I'm in a mood for a different watch. The Spring Drive is the king of all watches that no other watch can come close regardless of price range.
Michael Ponomareff+ So, you actually think Grand Seikos are assembled in retail stores? It never entered your mind that this is a demonstration piece?
This is just plain ugly. I don't how much branding went into making people think this is real artisanship when it's clearly just electronics. No matter how you look at it it's just a really well decorated quartz. Sorry for being negative but it seems to me people are going crazy for this thing for no real reason.
Ludde Larsson you have to buy so you will appreciate.😂
You know, I just wanted to type something really negative about your comment, but I just didn't in the hope that in the 4 months since you wrote this paragraph you somehow got educated about why a) your statement is not true, b) the Spring Drive is truly magnificent and c) it is crazy that it still can be had for so little money.
Yeah I'm gonna go with otobotrecords here and hope you learned why and where you were wrong.
The Spring Drive movement is automatic and regulated by a quartz, not quartz driven.
It has to be regulated by a quartz because there is no escapement built in the watch, else it wouldn't need a quartz right?
It doesn't use a battery because it generates the small current needed from the main spring, just like an automatic uses elastic energy stored in a spring to regulate itself and drive the hands.
So the movement is a hybrid of mechanical and quartz movements but definitely not a quartz driven movement like you're used to.
This is a concept of next level technology is something Swiss has tried and failed at and took well over 20 years to develop while most Swiss watches in same price range dropped in off shelf eta's in outsourced cases, many from china. The same people who bash it would be bragging non stop.had it been made by rolex/p.p
Seiko also won the most accurate pure mechanical movement in Swiss competitions to the point where the Swiss got rid of the competition out of embarassment.
I generally don't reply on TH-cam videos as I don't wish to be labelled as some keyboard warrior. I am looking at getting into watch repair and collecting myself for about the last 2 weeks. Prompted by a very difficult search to find someone that can restore my 7016-8001 flyback. Even from my short time looking, even I understand that this is not a Quartz movement.
