Hey I am curious about the omega seamaster ck2937, I own one myself (2937-1) and would like to know more about it. What i "know" already: It has the caliber 267 movement. Made 1956-1958ish. What i would like to know: 1.The differens between 2937-1 2937-2 2937-3 etc. 2.Some People call it a transition model, why? 3.why do they often have hands, dial or both that are similar to the Ranchero. (this could perhaps answer question 2 ?) 4. Anything really. here is som Photos of mine View attachment 606050 (The way i purchased it, I Will Change to a dark leather strap) View attachment 606051 Thats all, i wish to hear your thoughts.
