This 35mm. 1973 OMEGA SEAMASTER CHRONOMETER is one of the finest examples I have found. The steel case and original beads of rice bracelet sparkle. The high grade OMEGA automatic chronometer grade movement was just cleaned and is accurately ticking away. The correct OMEGA hesalite crystal and proper OMEGA winding crown are installed. This Omega chronometer vintage watch will fit up to an 8 inch wrist. Remember-this is NOT a regular Seamaster, but a much more desirable chronometer version, which is becoming hard to find.
