Hey folks, A few weeks ago I bought a Vintage Omega 2480 - 1 Automatic from a watch collector in Holland. Here are some specifications of the watch. Model : Omega 2480-1 Diameter : 37 mm Age : 1947 ( 11 mil ) Movement : Automatic bumper cal 351 So far so good, I wound the watch 10 to 15 times and it was working fine. During the first evening I've found out that the watch was giving me the incorrect time . I did some tests during the week and I've found out that that my second hand stops between 10 and 11. If i tick the glass or bumb the movment / winding , it wil continue. Sometimes the watch works great, but i Can't deny that the watch stops. I went back to the previous owner but he tells me, that he never had any problems with the movement. Now i'm wondering if someone in our community had some similar problems ? I went to 2 different watchmakers but they can't figure out whats wrong. Thanks for helping.
