This 35mm. 1969 Omega Seamaster Chronometer is an uncommon watch; having a 24 jewel chronometer grade automatic winding caliber 564 serviced movement. The chronometer grade Omega movements are usually found in the Constellation line of watches and much less seen in the Seamaster series. This watch has a very clean 35mm. steel case with sea monster screw-back, correct Omega winding crown and Omega hesalite signed crystal. There are no major dings or scratches on this case. The original dial and Dauphine hands look spectacular. The bonus Omega steel rice bracelet will fit up to a 6.5 inch wrist.
