A great video. I've just bought a couple of NH34s to build myself a GMT, and this is going to be a really handy reference for the vast majority of that movement! So much grease on that mainspring! Definitely looks like it's well worth giving these seiko NHs a full service.
Releasing power and tension on the main spring should ALWAYS be done before you remove the balance wheel, this should never be removed while it's moving, great way to damage it!!
@@MacroTime28800 I have a 4R35. It is almost exactly the same except for the bits that actuate/control the day wheel, no? I thought these movements had a plastic pallet fork, but I was pleased to see this 4R36 with a metallic and jeweled pallet fork. So that is exciting! (major nerd/geekness)
@@MacroTime28800 the reason I ask is because I saw this video the other day, and I thought, if Tissot uses a movement like this, surely Seiko at its lower price point, does as well. czcams.com/video/0VKoZ_Bdd7M/video.htmlsi=-usuhv2FSgMGPDRU
I didn't know at the time of making the video but it acts as a fuse. If the day or date is changed at the wrong time and something breaks, it will only be the plastic 👍
I've been watching your videos ever since... today's morning and I have to admit - they are great, giving my brain something fun to do while I'm performing my job. The only problem is - you're making it too interesting, which makes it hard to concentrate on my tasks at hand, but I'll manage :P

For the money the NH36 costs it is unbeatable. In my latest video I service Seiko 7005 movement and the Delta after the service is 18 seconds, 53 years old movement 👍
Great Leo. As always, an ideal video as a tutorial. I am going to disassemble and service my Seiko 4r36 with some fear and after watching your video twice. Until now I have always made Eta and some Vostok. But I have never dared with Seiko, watching the videos they seem more difficult to me. Allow me a question, in your opinion is a Seiko more difficult than an Eta? Or if I have made Eta I will have no problems with a Seiko. After this 4r I will go for a 6r that I have also seen that you have a video. Thank you.
It isn’t difficult at all. I think you probably feel a little uneasy because you’ve not done one before but once you’ve done one, you’ll realise that there’s nothing to worry about. You could always train on a cheap NH36 before you do the 4R 👍
@@MacroTime28800 Thanks Leo. It's a good idea to train with an NH36. I have some Seiko that, although they work well, have values of 1.0 ms error and 220-230 amplitude, including some 6r15. Right now I have just completely restored an ETA 2551 from 1968, which is very very small, and has run at +6 seconds per day...now I'm going to go for the Seiko. Thanks Leo.
Getting the mainspring barrel open without damaging the gears or the exterior was impossible for me. Next time I'm just replacing the complete barrel assembly, as Seiko recommends.
Does the movement come with minimal lubrication from the factory? Or does the watchmaker use a better quality set of lubricants? To achieve more accuracy?
Better quality, perhaps. There are never ending arguments which lubricants are the best lubricants. If you buy a movement, any movement, or a watch, the mechanism wouldn’t have been in motion for months, perhaps even years. The fresh lubricants will make a difference.
Hard to say. I have certainly seen broken metal parts in movements, setting lever springs etc. so we can’t say metal is 100% perfect. The plastic is not pretty, I’d also prefer the plastic not to be there but I think it will last for quite some time. If you are thinking of buying a Seiko that has plastic parts, I wouldn’t worry about it. Rolex caliber 3035 has plastic bushing in the minute pinion, it’s not just Seiko who’s guilty of plastic.
When you think about it, those gears are used for the day date change, so they are low usage. ETA's Powermatic 80 movement uses plastic for the escape wheel and pallet fork and get away with it.
Thanks for sharing this! Does the 4r36 also have the same plastic cog wheels as the ones found in this NH36? Just curious if there’s any difference between the two movements or if they are in fact identical in terms of parts. Thanks!
I've never worked on one but must likely they are the same. I've done 6R15 video, the Alpinist that that also has plastic. It acts as a 'fuse'. If you change the date or day at the wrong time when you shouldn't do it, it's the plastic that will break, not the other parts they interract with.
Personally, if it’s brand new, I’d ask for a replacement. If you bought it to practice on, start with a movement that works well and see whether you can take it apart, put it together and everything works well. If you got a movement/watch for a repair or service that would be different but a new movement, I’d get a replacement.
By following along with u... I did it. And it still works. Wow. Though the C clip was bi**h to return to its place. That was really my only snag. And I may have been a little rich on the lube. tnx. That was fun.
Nice video! Is there any big difference beetwen branded seiko and unbranded nh movts? I mean material quality first. I have a nh36 (built in a skx) with the 6r20's 28.800bph escapement system for 3 years. Accurate as the hell. I hope it will be reliable nh36. How often need service the escapement system?
I don’t think there is much difference between them. I have 6R24B here that looks very much the same as far as the materials go. The finishing is nicer on the 6R24B, you can see that on the bevelled edges but only under strong magnification. In my opinion, I would say get it serviced every five years or when the time keeping starts degrading, whichever comes first. Every watchmaker will have a different opinion how often to service watches, I’m comfortable servicing my watches every five years.
I don’t see any reason why not. They may have plastic parts inside them but even the old movements with plastic parts are fine. I have a few modern Seiko watches myself and I don’t have any issues with them. If there is a Seiko you like, go for it.

I enjoyed that, sad to see the quality has dropped a fair bit with Seiko if you consider the much higher quality levels of the 7009/6309, have yet to own a NHxx powered watch as I thought I got one in my recent acquisition of a new Lorus automatic and it turns out to be a 7S26C inside. Am this weekend attempting my first 7009 rebuild, have done two Soviet Slava's and both working superbly so now to wade in deep into the world of repairing 'em :D
I wasn’t sure where you were from that’s why I didn’t give you a direct link. It wouldn’t have been much of a help as I’m in the UK. I’m glad I was able to help 👍

Ok a cosa que se critica por su bajo coste bajo coste para Seiko debido a lo que es Seiko si este calibre lo uviese sacado otra casa suiza seguro que todo serían alagos luego es un calibre base que Seiko tiene un catálogo impresionante yo era al principio reticente pero hoy por hoy los NH y 4r son calibres a la altura de cualquier calibre denominado de batalla osea fiable y duradero
