Barrel broken tooth

[Giumollo]

Hi Guys,

just disassembled my Seiko NH35A and broke a barrel tooth, trying to open it.

Will it run when I reassemble it?

thank you all!

No, it will not run well.
Seiko barrels, as often mentioned are not meant to be opened.
If you have trouble finding a replacement PM your  address and I'll send an used one.

You need a new barrel.

Oh crap...

just checked Ebay and Cousins. No replacement.....

It is really nice of you to ship me one.

Not only will it not run well (if indeed it runs at all), it runs the risk of damaging the teeth of whatever it meshes with.

Part number 0201 083 Barrel Complete. So much I found out but nowhere to buy it.

If you broke a barrel tooth it was probably wound up, and there are likely other damaged wheels/pinions- have a good look at them.

The thing is, a barrel complete (e.g. 201.420) retail is £17.55, compare to £31.95 for the complete mov't. (prices excluding VAT).
It just doesn't make sense to stock, or even buy, the spare part.

I think, as mentioned, the OP broke it while trying to open the barrel to "service" the MS - that's never needed on modern Seiko, but something that beginners like to do anyway.

You're right. Saw Mark's video with the Seiko 5 and he did open the barrel. I just thought it was the natural thing to do. Be sure won't happen again. 

Thanks again

He's not the only one. Nicholas Hacko, a self-called master Watchmaker teaches the same in his incomplete 7S26 tutorial. If one has no better choice it can done, but very carefully.

Cousinsuk has it . Often the 0 isn't used when seaching seiko parts . i looked at 7S26 movement . That uses the same barrel. And you are not alone. Did the same on my first 7005 Seiko . Have the same construction. Have barrels if you need.

Perfect!!!

I was searching under NH35A. They indeed have it. £16.90.

I will order then. 

Thanks a lot!

Barrel and center wheel are different across A, B and C versions, details on my sheet: https://docs.google.com/spreadsheets/d/e/2PACX-1vRN2UULQKTfKmhRStZhDdIOIQrqd6sPB-g6x2SKyQQjOvTBjG_7TQXQhAT4f1WqAX5QAPkIimi-3jqd/pubhtml

I think only the C version is interchangeable with the NH3x. I am ready to send one to Giuseppe, but if he wants to buy from Cousins I suggest that for 15 pounds more he gets a complete new mov't, and use the current one for practice, resell or even build a custom watch.

Think your option is a better choice. I only search 7S26  and found that it had the same number. But as you say the C is the movement that is closest to the NH35 .
