I would appreciate any information on my watch. I don't feel comfortable opening the back, so no numbers.

 

Hi!

Does you feel a bump when you shake it back and forth?

If so it is probably a caliber 343 or caliber 351 reference 2577.

If not, I'm not sure but others may have good guesses (the 2846 is a snap-on).

These are just guesses based on the case shape and dial config. Have a watchmaker open the back for you and take pics. All will be revealed.

If the second hand is black, it's been replaced. It should also be gold.

Welcome!

 

Thanks, Yes it bumps when shaken, and the second hand is black.

 

Looks like a 2577 reference with a 35* movement. Early 1950s most likely. That’s about as far as we could get without photos of the inside.

 

Thank you. I'll have it serviced and get the details.
