Hello, today my grandpa gave me his old Omega watch, it's hand wound, and is very probably purchased in 1950. I'm quite certain that the bracelet and glass aren't original... but hey, the man had this watch for 65 years and it's still running, so fake or not is out of the question here. I only would be happy to get some identification here.
P.S. the back seem to have gone through some serious use, barely anything visible, just several numbers that can only be seen under deep examination. I've managed to capture some of them as well.
Thanks in advance!
