I don't see where I can find the cal number. It is definitely a bumper. Serial number is 10.2m, putting it between 1944 and 1947. 18k gold Case without crown is 35mm. So questions. 1) is it a 28.10? 2) is the dial original? Thanks, Frank

 

Definitely a 28.10 ra pc. Dial looks legit, but would need confirmation...

 

I'm leaning toward redial. Unless it's the angle of the photo, the minute markers are not lined up with the hours, between 6 and 12.

 

You are right. The 8'clock hour and minute do not align.

 

+1 for a redial, look at the gap between hour markers and minute track, it is not perfectly centered.
