This 1967 OMEGA SEAMASTER CHRONOMETER is NOT a common watch. The automatic winding chronometer grade caliber 564 movement is what one would find in a CONSTELLATION, but instead OMEGA produced a bunch of SEAMASTERS with the same chronometer grade movements. This movement was just cleaned and is accurate. The steel case is quite large, measuring 36.5mm with beefy and chamfer lugs and sea monster screw-back. Both the OMEGA hesalite crystal and correct OMEGA winding crown are present. This original dial is amazing-with “sparkly” pebble finish in steel gray having original baton markers and hands with black inset. This movement offers a date quick set feature when you pull the crown all the way out. This OMEGA has not been polished-all original condition and extremely pretty!
