Hi, what calibre it is ? Thank you !

 

If you post a photo of the dial side, showing the setting parts, and what size the movement is in lignes, then I might be able to help...

Cheers, Al

 

Revue. Not quite Revue 30 hunter, but close…

The stamp "DF&C" stands for Dimier Frères & Cie.

Check out this thread.

 

Could it be a Revue 56?

Likely so…
