Just returned from the watchmaker



Screw down bezel...



...and hinged case



All Sterling Silver





Correct case matching with second caseback





16 jewels movement with 5 adjustments and fine regulation



Patent by Jean Finger



A beautiful pearl in a small shell



And finally on the wrist...



...but...not only

 

Wow, what a fantastic watch! Not just the case and movement, the double-sunk, enamel dial is lovely. Looking forward to reading the patent. Thank you for the great photos and unique content.

 

Wow. Superb. What’s the diameter?

 

Killer watch!

 

Gorgeous.

 

Amazing it looks brand new! Any idea of the date of manufacture? 1920s?

 

Thanks guys.
The diameter is 32,5mm and 40mm lug to lug.
As for the date I think first half of the 20s.

This case was used by Rolex for one of his first waterproof watches, the "Submarine"
