Here are some pics for closer look.

Hello.
I am trying to find out more about Borel Fils pocket watch that I got from my family.

On inner cover is engraved following:
No 506144
Borel Fils & cie
Laferme 25.XI. 1939 (also signed on the cover).

Glass has a crack, it works.

Thank you for any expertise.

Kristel
