Hello everyone. .I'm new to this group. ..I have not been in the hobby very long. Learning about Omega watches. ...I went to a watch show this weekend and purchased a stainless steel Constellation. ...it was running. .then it stopped. ..I'm going to be taking it to my watch repair man. ...any thoughts on why it quit running? ..thanks in advance. ...

 

I don't know how new you are to vintage watches but the Connie is an automatic so it winds when you wear it. Put it on a desk it will eventually stop.

 

Unless you wind it at the crown...

 

Maybe the battery ran out?

 

Perhaps you wore on the wrong wrist?

 

you might get some extra response when you read through this thread
