I searched and didn't find a similar older thread on OF. If there was and I missed it, I apologize. Not my intent to create duplicate topic threads. Just found a ton of educational threads dealing with specific SM300 issues. Hence, being that I love all things vintage SM300, let's see lots of pics of them! Please show pics of your vintage SM300. I'll start with one of my beloved old SM300s-Mr. Kojak aka Mr. 165.014-63 sans insert. P.S.: Watchco SM300 pics welcome too!
Bezel is there, just the insert missing, as mentioned. I actually like the look very much myself, believe it or not. Those hands are proper for an 165.014.
There should be a serial number registry thread on all things 300. Seemed to slow down considerably in 2017
There's this but it's a little quiet... https://omegaforums.net/threads/seamaster-300-registry-and-general-information.41400/
