This is a full-sized uncommon 35mm 1970 Omega Seamaster chronometer having an amazingly clean original dial with subtle and amazing patina and original Dauphine handset. You rarely find these chronometer-grade Seamasters, as we normally see these chronometer-grade movements in the Constellation watches. The steel case is sleek, substantial, and in fine shape overall with the desired sea-monster relief logo on the case back. The winding crown is Omega and the Omega hesalite crystal is correct. The full-length Omega beads-of-rice bracelet will fit a 7.5″ wrist. The fine caliber 564 Omega automatic chronometer-grade movement was just cleaned and is accurate. These are amongst my favourite of all vintage Omega dress watches due to the clean lines and purity in design. These chronometer-grade Seamasters are becoming harder to find these days.
