Hi guys, I am selling a very cool Omega Seamaster Calendar with date window at 3 o'clock. In all honesty I don't know what reference it is. I bought it from my watchmaker who fully serviced it. I searched the internet and even looked here on Omegaforums but couldn't find one like this. So any help is welcome. Dial has developed a pretty nice patina. It seems it's often the case on these calendars. Crown looks like the original. Case-back has the seahorse logo in great condition. Unfortunately there is also an inscription. Case is very very close to mint. No scratches, no nicks. Looks unpolished to me. Mechanically it's running perfect since it has just been serviced. I give a 12 month guarantee on the movement. Pricing is hard when you don't know what you are selling. So if you find my price too high feel free to make an offer. Same if my price is too low. Price: 750 euros ( insured shipping included ) Payment: Bank transfer or PP ( +4% ) ( I give a full refund in case of any issue or if not as described ) Best regards, Bernard
