Hello!

I acquired this cal. 8 3/4 F Zenith tank last week. It likely dates to the late 1930's or early 1940's. It's a restoration piece as it needs a replacement glass and a new balance spring/mainspring, but otherwise seems to be in quite good condition and is quite a lovely little piece!

If anyone could provide info on the model/date/etc (as well as any potential authenticity concerns?), I'd appreciate it. The last photo shows a similar model from a catalogue with the same dial and hands that another enthusiast shared with me.

Also, if someone knows where I could find replacement glass or a cal. 8 3/4F (for parts), I would be grateful for the tip.

I cannot provide any useful insight but the glossy black dial and intricate steel case are fantastic. Great find and thanks for sharing!

 

Glad to hear your feedback regardless!

 

That enthusiast would be me

 

A generous and resourceful enthusiast at that, my friend!

 

From my Zenith repairs catalog hope this well help you !

Thank you for sharing this Rick. Indeed it seems it's part 721 (complete balance) that I'm searching for.

 

Similar case as this Tissot:

Lovely dial on that Tissot and I like the rose gold touch. For those interested, I've also found similar cases on these Longines and Tiffany watches (both on eBay):
