Hello, I'd greatly appreciate some help with a, perhaps ambitious, restoration project. I dove into the hobby close to 6 months ago but have been consuming servicing and restoration content for a few years.

I purchased the watch (non-running, missing crown) from an eBay auction for what I believed to be a reasonable price. I received the watch and went through the frightening process of opening it, but was pleasantly surprise with an immaculate dial!

There is some debris and rust on the movement, but most seems to be superficial/surface and only the case tube was nearly fully eaten away. The movement (cal. 1020) does run! As helpful as these forums have been for other projects and information, I've had trouble to find much of anything about this specific piece. Ref#166.129
A parts list would be phenomenal. The case tube and seal o-ring is the minimum I need.

Thanks for any info you can share!

How did you get on with the restoration? I’ve got a similar stainless steel watch would be interested in finding out.
