Produced by Omega for the Peruvian Airforce and specially branded as a Flightmaster not a Railmaster, these were made in tiny numbers on special order by Omega as the Air Force didn't like the Railmaster script! Made long before the well known cal 910/11 Flightmaster was born! The only difference between this watch and the Railmaster is the script on the dial and the engraving on the case back, oh and the fact that it still have half a day to run and is already at £12000, where as even a near perfect Railmaster would have topped out at £6000
