Hello, I am looking for more informations about an omega constellation which belongs to a friend. I am wondering if you could tell me more about its model numbers and if it looks genuine to you. I know that the watch is from 1967 and has a cal.564. Here are some photos : Best regards.
The reference number will be on the inside of the back case. Find that number and Google it for comparison watches.
A pix of the inside of the case back will show your ref number wow you and I were typing at same time
Look at this listing. I'd say they're the same reference but someone will correct me. https://omegaforums.net/threads/1967-omega-constellation-ref-168-018-ss-case-cal-564-serviced.80749/
