I did not open the case yet so unclear at this moment. It’s a pré-seamaster bumper, I think with cal. 340. I saw some similar watches in the ref. range 2402 - 2581 but can only confirm through opening.
So I did a little research and I think its a 2662-2. Heres a link to one for sale. https://vintagecaliber.com/collections/all/products/1952-omega-ref-2662-2-bumper-automatic
Thank you. From memory 145.0040, cal 861.I think the bracelet is correct for the Teutonic Mk5 case. I'm fond of it.
Chunky ultra-chron today. Probably these least popular ultra-chron style! Yeah, too lazy to set the date.
Speedmaster 3570 again. Have to admit, it is hard to not wear...I now understand the attraction of the Moonwatch!
