Here is a vintage stainless steel Omega Flightmaster caliber 911 dating to 1971 and measuring 43x52mm. The caliber 911 (based on the caliber 861) manual winding Omega movement was just fully overhauled, cleaned, and is keeping accurate time. The original mineral-glass Omega crystal is without a scratch. The original dial and hands are about as clean as they come (essentially like new). The jet plane on the case back is still very readable. The 20mm Omega stainless steel original bracelet has minimal stretch and looks very good. Also, the original coloured pushers are still present and in good condition.
