This is one of the largest round cased Omega Constellation produced in the 1960’s. This 35mm. stainless steel OMEGA CONSTELLATION dates to 1966 and looks large on the wrist due to the all-dial narrow-bezel appearance of this fine watch. The chronometer grade OMEGA caliber 564 movement was just cleaned and is accurate. The screw back has a crisp observatory raised relief emblem. The dial and hands are completely original with great looking patina. The date has a quick-set feature when you pull the crown all the way out. This watch is VERY uncommon in the oversized case with pie-pan dial.
