Hi guys, I am selling this super nice and rare Omega Bumper reference 2421-1. Movement is a cal. 2810RA. I haven't made any pics of the movement but I will at the buyer's request. The watch belonged to my watchmaker and was fully serviced before I bought it. The movement is super clean. As far as I know the watch is completely original with the original radium on dial and hands. Also the crown is an original and has the Omega flat feet logo. Please notice that around the case-back there should be a metal ring to keep the case-back safely on its place. Very often this ring is missing like on this watch. I can assure though the case-back sits firmly clicked on the case and will not fall off. I checked with my watchmaker. Otherwise I would not have bought the watch. It's even really hard to open the watch. Dial has developed a very nice even patina. You like that patina or you don't like it. Hands are missing a part of the luminous material but what is still there seems pretty stable. Case is very good and looks unpolished to me. Size is 35mm which was considered as oversize at that time/. Mechanically the watch is running perfect. I give a 12 month guarantee on the movement. I am including a new and nicely matching black rally strap. Price: 580 euro ----> 385 euro ---> 300 euro ( included an insured shipping and the black strap ) ( I give a full refund if the watch would not be as described ) Best regards, Bernard
