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 chamfer lugs and a sea-monster screw-back. Both the Omega hesalite crystal and correct Omega winding crown are present. This original dial is amazing with a sparkly pebble finish in steel grey, original baton markers, and original hands with black inset. This movement offers a quick-set date feature when you pull the crown all the way out. This all-original Omega has not been polished and is extremely pretty!
