Very cool vintage Omega. Automatic movement. Rotor seems to be a little loose, but it works great. The glass has a couple of light scratches in it, it looks worse in the pictures than it does in person. It could probably be buffed out, but I’m not comfortable doing that myself. I’ve tried multiple times to find the reference number for this watch, but it seems to be somewhat rare and I have not seen another one like it. So I’m not entirely sure exactly what it is.
