Hi Guys, I'm considering buying my fist vintage watch. I was hoping you guys could help, telling me which Omega this is. Cal.266 Ref.2609
C'mon now, at least say "Hello" and maybe introduce yourself before you ask a question! It looks like one I've seen on Ebay, correct?
You have your answer in your post. It's a reference 2609 with a cal. 266 manual wind movement. Of course, this is all speculation without seeing inside the watch. https://www.omegawatches.com/planet-omega/heritage/vintage-details/15119/
Based on the one picture I'd be willing to wager that the watch in question has had a redial. Looks like the 2609 is often given the Mil. look by unscrupulous redialer's https://omegaforums.net/threads/can-you-help-me-identify-this-omega-2609.18889/
