@jdm Hi jdm, is there a short list of parts that are (or are not) compatible between the NH and 7S series? Also, what do you think of the reliability between the NH35 and the other major Japanese and Swiss movements. Thanks.

Best is to get the cheapest 7S26 "for parts" and take it from there,  that will give you more parts as well.

I take it the jewels are not readily available.
First time trying to install the shock springs, lost both jewels.
Not a good day.

Hi Peter  I have attached the Series 3X  tech guide and the NH36 tech sheet. The Tech guide has all the parts and the oiling plus assembly information   hope you find it useful.  jdms suggestion of sourcing bits from ebay may be the best course of action of see If you can lay you hands on a Bombay special from India or check out cousins uk.       cheers

These are best left alone, lubricate from outside with a very fine pin applicator.

I've been using this sheet for oiling, it's the 13-2 and no. 13 is the barrel bridge. Looks like a scrap S726 will be my option as there is no part number so I can't search for it on Cousins website.

      Chronograph Pusher Rod for EB8371-67 Snapped and Stuck in Button. Can't Unscrew.

      By watchweasol · Posted

      Hi. Yes I get it , the slot in the end I’d to allow you to screw the button on whilst holding the pusher shaft. To remove the pusher tube you will need a tool such as the one shown by Richard. I think Ali Express the Chinese Amazon has replicas of the Horotec system for a lot less money, how effective they are not having had to use one. But as you said the way to go is complete removal and replacement, bodging it up will  lead to a repeat failure

      30T2 adjustment of timing washers

      By JohnR725 · Posted

      One of the things that I've been bothered with lately is timekeeping? For instance a 90-year-old pocket watch what so to timekeeping was it supposed to keep? They publish railroad timekeeping but I don't know how well normal non-railroad watches were supposed to keep time. The reason why the question comes up for me is I spend a lot of time at work adjusting watches to keep really really good time  because I have to please my boss where as when the watch was made I have to wonder what kind timekeeping would've been acceptable. After all they typically didn't have timing machines 100 years ago and they were timing and six positions certainly not for the non-railroad grade watch. On the other hand I do get paid by the hour so maybe I shouldn't be concerned of how much time I Spend trying to make everything keep chronometer timekeeping almost. Citing a Delta of 40 seconds for a 90-year-old watch is quite outstanding.

      Is this pallet fork over-locking?

      By JohnR725 · Posted

      That's an interesting question which I don't think I've seen explained anywhere. But I think the problem will go away just about instantaneously. In other words the  coating is really thin and it should go away almost immediately. So the problem should resolve itself extremely fast.

      I experienced that different types of shellac and their ages are affected differently by IPA. Sometimes the shellac dissolves in a few seconds and sometimes several minutes are required. Nowadays I never let shellac come into contact with IPA. It's a hotly debated topic here on WRT if you search. Like John, I don't think you need to worry about the weight of the shellac, but instead that it might start rubbing against something. When I learned how to adjust pallet stones, I tried documenting my experiences in this thread. Hopefully, it can help you. I personally don't believe in the idea of abrading the epilame before oiling so I don't think you need to think or worry about it. The only time I've heard anyone mention this is Alex on the YouTube channel Watch Repair Tutorials but actually no one else. I'm not saying it's "wrong" just that I don't think it's necessary or adds anything.
