For sale an Omega Seamaster Chronograph reference ck2907-1 from 1958 (15.147.xxx) with its famous Cal 321 (v1 with symmetric bridge). I would like to keep it but sadly choices must be done… as usual. Watch comes with leather strap, no box, no papers, no extract. Case is flawless with super fat lugs, slight marks of wear. Size is 35-36mm. Crown is a later (late 60s - 70s) replacement Dial is very clean with all radium plots. It has patinated very well with tones of beige. Radium still glows under UV light and fades quickly. Movement is cal 321. It runs perfectly well, but I have no history of service. Caseback has a misprint. It is written Seemaster instead of Seamaster. Sea in german is See Asking 4300 EUR / 4950USD net to my account - No trades, no ridiculous offer please I am located in Geneva, Switzerland. Watch can be sent anywhere from Switzerland or EU. F2F is preferable. I have plenty of references, I have bought and sold many watches on OF and through Instagram (same account name) Additional photos upon request
