I searched all forum to find posts about this bracelet but didn’t have any luck. It’s 1502 no12, with end links numbered 11. Can you help me? Is it fake? If it’s original what year you think it was made and for which model? Do you think it’s for a constellation?
Some more info regarding the 1502/11 bracelet https://omegaforums.net/threads/1502-11-bracelet-with-166-010-seamaster.80837/
I don't see any red flags regarding originality, looks genuine and well worn. I have seen 11 endlinks on Seamasters mostly but I can imagine they fit 60s Connies also... Hope that helps
