[@MrCROBosanceros]

2:46, I own Seiko SPB053 with 6R15 movement. It is a slightly bigger watch than Seiko SPB143 with a narrow bezel with a unique colour that sometimes appears to be blue and sometimes green, depending on the light. It is for me one of the most beautiful divers watches ever made. It is a slightly bigger watch than Seiko SPB143. It is running exactly +4 seconds every day. I'm extremely disgusted with Seiko and even more disgusted with myself for believing in Seiko when watching this video. Where is the watch case made? Seiko, is it made in Japan or is it China? The outside is engraving Japan and the inside of the watch cover is engraved, China case and most people will never see the inner side of the watch case cover except the watchmaker. I know, it doesn't say made in Japan but why is there Japan? What else is true about Seiko products? So my watch is most likely made in China and I don't admire it anymore from this moment. How much do we have to spend to get a Japanese watch? I don't believe anymore that even Marine Master is made in Japan or even one of those limited and expensive 1965 "62 MAS" Re-Creation watches I always hoped to own one day. I don't believe that Grand Seiko watches are created and made by "artisans" in some studio looking at mountains, lakes and birch wood outside of the studio. My f. ass! All those watches are made by slave labour in some shit holes factories in China and run by commies. I will never buy Seiko again!

[@4by_yotaguy373]

You know, I was unpleasantly surprised when I saw that too. I currently own SBP147, SPB213, SPB105 that all state "Japan" on the dial, "Japan" on the case back, and even on the Seiko site, and all the reviews! I'm tempted to purchase a watch case opener off Amazon and open all mine up to take a look! I wonder if it's a similar thing like SNAP-ON had throughout all last decade where they were still branding a lot of their tools "MADE IN USA", when they were really "Assembled In USA With Globally Sourced Parts". They finally got called out on it and now all their handled ratchets, and many other tools, don't say anything about USA stamped on them anymore. Because all their handles and the other parts are made in China! 😡

[@4by_yotaguy373]

So I wonder if Seiko can make the cases in China, but make movements in Japan, and assemble in Japan, and still call it "MADE IN JAPAN"?? 😕

[@4by_yotaguy373]

Oh also to add, my SPB105 green-gilt-dialed 68 diver remake, states directly "MADE IN JAPAN" on the back cover.

[@MrCROBosanceros]

@@4by_yotaguy373 I can't believe this coincidence. When I wrote the comment, I also wanted to mention Snap-on tools but I thought most people who are interested in watches don't care about mechanical tools and I didn't want to complicate my comment even more. Last few years I tend to buy mostly Snap-on and Proto wrenches, sockets, and ratchets. When I'm willing to pay for one little wrench as much money that could get me more than the whole set of Chinese-made knockoff wrenches in my local auto store, of course, I would be pissed off if I found out they are Chinese made. I paid over 1000 U.S. Dollars for my last American-made torque wrench. I could've bought a Chinese torque wrench for 300 Dollars. People always say, the Chinese now make quality stuff or they say, everybody makes stuff in China now. That's what it is.

A very nice video. May I suggest hacking the movement to stop the movement while adjusting it? To avoid any damage to the balance spring.

[@robertuskoppies444]

Excellent explanation. Simple but sound. I put my SPB239 on a timegrapher today, adjusted the beat error and regulated the time. The six positions were extremely different, ranging from -15 to -54 seconds. On average, the watch was at over minus 30 seconds. I saw that the regulator pin was almost completely at the minus setting. I wonder who assembles those watches and regulates them to fully minus, resulting in an extremely bad accuracy. It took me over an hour to fix the problem, now it's on my wrist and we'll see in a few days if I have to re-adjust it again, as the six positions were between +7 and -23.... Thanks again for sharing!

[@tomhill4003]

Very nicely explained! I feel like I totally get it after watching this. One question: do you run the movement through the various positions after regulation? I imagine there's a law of averages involved in getting this right.

[@bangy55]

Dimitri, you probably know that I really enjoy your videos and I think this is a beautiful watch with a very good movement. But, you stumped me when you knew which direction to move the stud for correcting the beat error without first moving it to see which direction it needed to go. I don't think you're psychic so you most likely know something I don't. Since I often work on vintage watches with no adjustable stud for correcting the beat error, it would be incredibly helpful to know how you do that. It would save me a lot of time, not to mention money buying new hairsprings after destroying them adjusting the collet.

[@petercampbell3828]

Nice clear instruction. Are you planning on going into the Seiko balance spring sales business?😄

[@rydock]

Great video! I also have a Seiko SPB143 that is running super slow. I've tried to take the caseback off mine with my jaxa wrench, and it seems to be screwed in way tighter than any Seiko I've ever encountered. Have you noticed that the one you worked on was on tight as well?

[@goodspeed1618]

Seiko has a great history and has always been good, but I also have questions about the new generation of Seiko timepieces, especially the more expensive models like this Seiko Prospex SPB143J1. Whether this is still good, value for money, I don't think so.. A Seiko 5, value for money, yes! What do you guys think?

[@licensetochill79]

Could you do a video on how to clean and lubricate a reversing gear, and you would use on a reversing gear

[@universesorion6501]

Yes

[@ItsNeverTooHot4Leather]

I agree 100%. The amount of money that Seiko is charging for these watches is ridiculous. The quality (and quality control) simply isn't there for $1,000+, and the movements leave a lot to be desired in terms of accuracy right out of the box. Sad that Seiko has lost its way so much since the 1960s-1970s.

[@shipmate3577]

Hamilton and Tissot are now the best bang for buck name watch brands. ETA 2824 and SW-220 are better than Seiko's 6R-series and on par with their 8L-series movements in regards to beat frequency and accuracy . Plus, Seiko bracelets and clasps are trash. However, I do like Seiko's sun dials, spring bars, and dial hands.

[@ccooper8785]

Very good but how does it perform over time as the watch runs down? My experience is that as these watches run down they get increasingly inaccurate. The longer the power reserve, the worse they perform. This is just 1 reason they need to be consigned to the bin and replaced with decent mecaquartz movements. If someone had told me 20 years ago that people would be paying large amounts for new and unknown Chinese brands fitted with ancient, bulky Seiko automatic movements, I never would have believed them...

to get a perfect reading do you need to fully wind the movement before measuring or Half power is enough.

Not all watch movements have movable hairspring fastening studs. They are set usually by turning the hairspring inner fastening collar and that's NOT for beginners! In the Seiko in this video the stud is turnable just like the time regulating arm.

[@cashau2965]

@@Ba_Yegu thank you for your note Yegu...it's true this is not for beginners! I've seen a video some time ago where a special tool was used to move two pins between which the spring is moving and this somehow regulated the spring action , but I can't remember who made the video.

Since the beat error is always a positive number (it’s the absolute difference of the two rotation times), how do you know whether to turn the stud carrier clockwise or counterclockwise other than trial and error? I regulated a Seiko NH35A once from 1.3ms to 0.6ms, but when I tried to get it further down, the balance wheel stopped and the watch was permanently damaged!

[@nunyabusiness9056]

Hey thanks for the vid but is this a bit misleading? i just regulated one of my 7s26 seikos for the first time and it seems like if you move one lever it throws off the what the other does. If i change the beat error it drastically slows or speeds up the watch. If i get the beat error to .1 (lowest i could get) the watch would be about -80 seconds. If i speed up the watch to +/- zero it would throw the beat error up to like 4 ms. I had to just keep adjusting these levers trying to do this balancing act for like hours before i finally got -1 s/d and .3 beat error. Is this not normal or does just nobody talk about this in any tutorials for some reason?

[@vlickbrickersom7392]

This is normal. Adjusting the beat error changes the s/d so you have to adjust accordingly.

[@w4447]

[@wannabe_sailor_777smith6]

Hello, what if the lift angle should be 54 degrees but is 53 after regulating rate and BE. Is this ok?

[@Spurdospaerde692]

The lift angle is a fixed property of each calibre, it can't be adjusted. If you have e.g. a Seiko 6R34 movement, you look up what the lift angle is for this calibre, and enter it into the timegrapher. The timegrapher uses this variable to calculate the amplitude. If all you want to do is to regulate your watch, you don't even need to know nor enter the correct lift angle. Should you enter the wrong lift angle, all that happens is that the calculated amplitude will be wrong. The measured rate isn't affected.

[@jackjax7921]

What if the beat error never goes down and stays at 9ms?

[@LaFritePerreGoat]

How do you calculate an average to compensate for positionals error from those 4 positions then? I see your timegrapher calculate it automatically but the weishi 1000 doesn't. I know that the dial up should weighted a bit of you work alot at a desk like me but how much? Thanks.

[@Ba_Yegu]

IMHO regarding the Regulator's own watch the best method to regulate it would be wearing the watch for a week just as usual and check the accuracy once a day. After a week the watch is put on the Timegrapher and checked against it for comparison and to determine the beat error. If the "Real World" accuracy is lets say +7sec/day and the mean accuracy on Timegrapher would be +11 but after compensating for the beat error +19sec/day one wouldn't like to adjust away the whole 19 secs, but only 15 or slightly less. Of course this method is not for professional watchmakers, who wouldn't wear their arms filled of customer's watches for a week a piece... (Automatic Watch Winders are useless in this.) I'd prefer a watch running slightly fast but wouldn't touch a non-chronometer movement which runs ±5secs/day. It's perfectly fine, believe me! 😄

@@ant.9940 My Seiko SARB017 Alpinist with a 6R15 had similar amplitude and -19 seconds per day (within Seiko's generous tolerances they give themselves) and was brand new. These 6R movements appear to be developed from the 7s26 found in Seiko 5s which also tend to suffer from low amplitude. The fact that Seiko puts these in $1,000+ watches is frankly bizarre. At that price point they should at least get the 6L movements.

Seiko has a great history and has always been good, but I also have questions about the new generation of Seiko timepieces, especially the more expensive models. Whether this is still good, value for money. I don't think so.. A Seiko 5, value for money, yes!

I did NOT see you make any adjustments or movements ???

It is "too slow" NOT "to slow".

You do realize most of the mechanical timepiece GOATs in the world currently, that English is not their first language?
