The 1969 Omega Seamaster chronometer is an uncommon watch. These watches were produced in much smaller numbers than the regular Seamaster or Constellation. The chronometer-grade 24-jewel (adjusted to five positions) caliber 564 automatic winding movement is normally found in the Omega Constellation line of watches and is less common to find in a Seamaster such as this example. This watch exudes class and sophistication. Look at the original pristine dial with Dauphine hands and steel markers. The Omega-signed crystal and winding crown are present, as is the raised-logo sea monster screw-down case back. The movement was just cleaned and is accurate. The full sized 35mm case is larger than a Rolex Air-King from the same era and I would say better-looking beacuase of the Dauphine hands.
