This ref. 145.036 OMEGA FLIGHTMASTER is absolutely clean as they come. The 33 million serial # dates this watch to 1971. OMEGA CANADA just cleaned the caliber 911 manual winding movement and it is sparkling. The case was properly restored by OMEGA as well and looks new. The dial and hands are original. The pushers are all new old stock. Even the original waterproof and accuracy slips are included (from Omega). You will not find a cleaner example.
