NH36 cap jewel

[PeterS]

I've lost the cap jewel (NH36) that goes in the barrel/train wheel bridge. Seiko doesn't specify the part number, it looks like it's part of the bridge.
Any idea where I could get a replacement?

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

@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.

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.

I cleaned them and I was going to oil them with the 1A oiler.
