This 35mm. 1969 OMEGA SEAMASTER CHRONOMETER is amongst the best value in a vintage watch. It has it all going! The look is clean-lined, stainless steel sea monster case back, signed OMEGA crown, recently cleaned and accurate automatic winding CHRONOMETER GRADE caliber 564 movement, original dial with steel markers and Dauphine hands and signed OMEGA hesalite crystal. This watch is much more uncommon than a regular Seamaster, because it has a CHRONOMETER GRADE movement (adjusted to 5 positions and temperatures). These watches can be worn daily for a lifetime+ and handed down. They are rugged and reliable. Look at the sparkling case and AMAZING original dial on this vintage OMEGA!
