This Omega Flightmaster was just fully (and expensively) serviced by OMEGA. This is the fine manual winding caliber 911 movement, just cleaned and sparkling like new. The 42mm. case is spectacular. All pushers and crowns are new old stock. This watch even passed the waterproof test; however, we recommend not getting it wet. This 145.026 is a prime example of a caliber 911 Omega Flightmaster.
