I bought a vintage Omega Seamaster Cosmos from @Davidt in the following thread. https://omegaforums.net/threads/omega-seamaster-cosmic-136-017-silver-dial-w-crosshair.70486/ The descriptions and pictures in the thread are very thorough and accurate. Watch is in the exact conditions as described. Communication was smooth, prompt, and friendly. Packaging was safe and shipping was fast. It was my first buy on OF, I do not even have the privileges to post in the trading forums and did the transaction via private messages. David was trusty, but of course after careful due diligence. Overall I'm very satisfied with the purchase, and David is a great seller. Highly recommend! Robin
