I've been wanting to pick up a vintage Omega for some time now and today was the day! The guys from Hodinkee had a pop up sale in San Francisco this weekend and I found something I really liked. I'm a total newbie when it comes to vintage Omega and would love any info that anyone could provide. It has a large case diameter for a vintage watch at 36.6mm and the movement is hand wound and beats at 18,000 bph. Sorry about the iPhone pics, it is all I have at this time. I know can have a lot more info if i get the caseback off but I don't feel comfortable doing that on my own. Thanks in advance for the info!
