Hi forum members, a "watch friend" of mine recently acquired the watch on the left, can you experts chime in on what model it is etc..I've got to admit that I'm completely smitten with it...The silver dial reminds me alot of the Daytona 6263 my late father -in-law had..Would love to hear all about it!!
It is next to my 105012CB

 

I believe now it is a ref 101.010?

 

Looks right.

 

Plenty of non-speedy 321s here: https://omegaforums.net/threads/not-all-321s-are-speedmasters.22332/
