This forum is really bad for the addiction! Not only does it feed my speedmaster obsession, it has recently got me hooked on vintage constellation. I've been searching for a good pie pan example and this one popped up on a local listing. An hour drive later I found myself chatting with an old gentleman who has had this watch for over 50 years. What I know about it: Ref 168.004 Cal 561 with 20 million serial # Dial looks original to me but would like input Case looks good, not polished much, 36mm diameter, 18mm between lugs Case back has all the stars Second hand was probably replaced sometime ago, there are 3 service markings on the case back Movement needs a good cleaning, maybe a few replacement parts as well, like the rotor post I've taken some pictures, please take a look and let me know what you think!
