It took me 2 weeks just to regulate a 4R36 movement to about +/-2secs. It's not easy because slight movement can make the movement out significantly. Time grapher can only detect it on that moment and after a few hours than you see it running fast or slow. Time Apps is the best for movement regulation. Another thing is magnetism can make the movement go crazy so invest in a demagnetizer. Demagnetise your watch every month or 2.
Very similar to our experience it sales a great deal of time to regulate these movements. We also had to revisit it a few times as it seemed to settle down and over weeks change.
I have the same model. Mine has been +\- 0,5 to 1 sec per day. Mine is pretty good aligned as well (had to return one that wasn't tough) You need some luck with the cheaper Seikos. But there's a big difference between "swiss movements" and "swiss movements" just because they're swiss doesn't mean they have to be better than Japanese. The price is usually what matters. Expensive swiss=better than Japanese. Expensive japanese=better than cheaper swiss. Generally.
Yep this was the third mechanical seiko I had behave erratically. We put a few ETA watches up agains it on the timegrapher and they seemed to perform better including a Hamilton khaki base model. The think eta seems to stay the same depending on orientation of the movement, where as the Japanese ones behave differently based on the same variables. I can’t think of any cheaper Swiss movements? When I talk about Swiss I mean either ETA or Sellita. I think in the sub $500 mark you could get a Hamilton with an ETA that would perform much better than a seiko of a similar price point. I think in the higher end like the seiko hi-beat or Spring drive then I imagine they perform better than the comparable Swiss.
I have a watch with a NH35 that was running -2 to -3 spd which is pretty good. Not sure if anyone else feels the same, but I hate having a watch that runs slow. I’d honestly rather have a watch run +10 spd than -3 spd. I ended up regulating it and now it’s running +8-10 spd. I may try to dial it in a little better. I can totally relate to what Kris is saying about the timegrapher being a snapshot. I’m using the same app for checking the time on my watch. You can get your watch at 0.0 spd dial down, but when you turn it to a different position, it changes to +5 spd. It truly is an art. I’ve also found less positional variation in the ETA movements I’ve regulated compared to Seiko. I have a Steinhart I regulated that is averaging +0.5 spd. It took a lot of trial and error.
That’s very interesting. Seiko rates the 4r36 to -25 to + 40 a day. Seiko would of considered yours in range. I have heard that Seikos are designed to be worn, and the accuracy would very greatly from wearing it to it just sitting. I had a problem with a Seiko Samurai, which has the 4r35. It was losing almost 2 minutes (120 seconds ) a day, which is unacceptable. I brought to a local jeweler who charged )$130, it’s now much better , but still losing.
Yes I think it would have been in range but those are crazy ranges that seiko lists. I had to see if I could get is a bit tighter. and it varies a lot depending on how the watch is positioned. It has made me thing again about Seiko like I mentioned in the collection review, maybe a Grand Seiko one day
Hi Ray, yes sound like it, those are great results. I prefer the TMI movements over the seiko branded ones. I would be interested to see it on a timegrapher
@@CasualWatchReviews I am interested in that too. I know Seiko movements perform very differently on wrist compared to on a timegrapher. I need to get the mod pressure tested, so I'll pop it on a timegrapher at Tue watchmaker.
I love mod you have done on your Turtle, very subtle and nice - you are right the hands make a big difference. I am also happy you were able to get it regulated to your satisfaction. This video demonstrates what mods take - money and time. It also demonstrates why someone would (should) mod - a beautiful personalized watch. Fantastic video, thank you Sam :)
Hi Jeffrey, yes I'm more than happy with it now... cost way to much but I'm happy with it. I keep flirting with the idea of trying to regulate a watch myself but I know I would get carried away and end up with movements and watch parts all over my house!
This is a great video Sam, terrific content. I don’t know if it’s worth trying too much to try to tune an unadjusted Seiko movement. I’m curious if it will hold over time. I adjust some of my watches on the Timegrapher. It just takes patience. Grab a Vostok and go for it!
I buy cheap Chinese ETA clones to practice on. I get most of my Seiko's in the 4-10 sec per day fast. I understand that a NH35/60 costs less than $50 so I can't expect them to regulate like an ETA at $200. When I take a 7s26 out of a Seiko 5 or SKX I get another movement to play with and learn from.
Hi Jim, I think this is how Kris taught himself.That would make a great upload putting and ETA in a seiko, it would probably start some 'lively' comments.
Nice to have you back. Very interesting. It looks fab. I hope it’s getting some wrist time. It does you credit, that you didn’t name the people that let you down. I don’t know if it’s just a phase, but I’m starting to appreciate the accuracy and convenience of a grab and go, quartz or solar. I guess I’m just getting old and boring. It was good to see the regulation progress, and it led me to wonder, if a hand wound watch, would be more or less accurate than an automatic? Whilst the mechanics are the same, there would be less mass, and so presumably, less move and deviate. Just a rhetorical question Sam, I’m not setting your homework. Nice video.
That may actually make for a good upload. I can see the logic, less movement in the watch case due to the lack of a rotor. Oh and yes sorry about the irregular upload schedule, I started a new job a few months ago and its a lot more involved than the old one, also a lot more fun!
If you are so concerned with accuracy go with quartz! I don't think that a mechanical watch with a 10-15 seconds lag is a huge problem. My Tudor black bay watch runs +10 sec/day and I don't sweat it.
I do have more quartz in the collection than mechanical. If that is right, your BB58 is running 10-15 seconds, that is well out of range for that watch I think. That movement is COSC rated so should be closer to +/- 4 seconds, I would get that looked at if that was me. Even if its the standard Black Black that uses an ETA movement, that can be timed to COSC also but not sure Tudor did it as a default.
Great video! For the pressure testing, the dial and movement are taken out of the watch. That way if there is a leak, your movement doesn’t get soaked.
Good video on what can be done with modding a Seiko but the question should be "should you"? For that kind of money you can purchase some very nice watches like a Longines HydroConquest, Hamilton Khaki Navy Frogman, Certina DS Action Diver, or a Tissot Seastar 1000. Thanks, enjoy the channel very much.
Yes, I totally agree and they would have likely (especially the hammy) been a lot more accurate. This was a review and also a cautionary tale of how I spent way too much on this watch!
Oh glad you enjoyed it... I thought I had for sure made this one too long winded and thats why the views have not been strong. But it was quite a journey that watch!
Does anyone know if any Seiko dive watches have a 33.5.mm dial and a 4'oclock crown position? Most Seiko dive watches have 28.5mm dials. I bought a Seiko SRPC68 "Root Beer Bottl Cap". I love the brown dial, but hated the shiny copper corloed aluminum bezel, so I removed the bezel and discarded it. I thought there would be dozens of aftermarket bezels available. Not only was that incorrect, but there are no bezels available even from Seiko. I would like to buy a Seiko watch case I can transfer the movement/ dial into.
Great video Sam. Happy Xmas. You two work well together let's hope it's doesn't end up like TGV and well anyone who he has ever done a vlog with.....😂😂😂😂
Hey, yes I will probably do some more uploads with Kris. yes, TGV has had a few 'guests' never to been seen again... although that plastic dinosaur has had a good run.

We found the same, the Swiss ones we tried were all consistent regardless of position!

A very interesting video. Your content is a cut above the usual basic reviews. Well done son.
I appreciate that, I try and mix it up a bit, I should do more stuff like this. A challenge for the new year!
The NH36 that I bought off eBay in my SKX mod is running within 1 second a day. I guess I got really lucky

Hey, thanks for commenting! We liked living dangerously!
Living dangerously but costly. ...lol
Great story! Really cool to understand that mod process and the time/dollar costs. Well done!
Hey Chris, yep I spent way to much on this one but it made for a good upload! Glad you liked it.

Hey Alan... thanks for the reminder forgot to put it in the description bit.ly/2rnggTA
Excellent video Sam, really interesting.
Oh glad you enjoyed it... I thought I had for sure made this one too long winded and thats why the views have not been strong. But it was quite a journey that watch!
@@CasualWatchReviews love stuff like this, love the channel as well, cheers Sam.
Hi love the bracelet on your turtle may I ask any chance I could get one for my turtle at all chears

Yes I couldn't agree more! a lot to spend but if I did it again I have learned a lot.
Fascinating...great content Sam!
Glad you enjoyed it, I need to do more stuff like this.

@@CasualWatchReviews That's cause he can't run away!!!
Very interesting!
Thanks Mike and thanks for watching!
The dude looks like Matt Damon
not worth it . just for a seiko... for that price could have got a better watch ....... cheers
Yep it was a lot to spend, I agree!
Thanks for the great video! Now this is a proper Seiko!
Yep, I honestly really like it now. I know you have good luck with your Seikos timing wise, I must just be unlucky with them!
The Casual Watch Reviewer - I’m sure mine are off as well, but honestly I care more about aesthetics at the end of the day 😂
