Very rarely seen on the market, the Flightmaster was the last collection in which Omega developed a mechanical movement specifically tailored for pilots. The dial of the Flightmaster may appear busy with seven hands, but Omega employed clever color manipulation to ensure optimal legibility for pilots in the flight cabin. Different colors were used to distinguish the various functions: orange for the chronograph, white for timekeeping, blue for the second time zone, and black for the inner rotating bezel. To enhance user-friendliness, similarly colored circular markings are found at the tips of the pushers as well.

Earlier versions of the Flightmaster utilized a Lemania-based calibre 911 movement, which was similar to the 1968 Speedmaster calibre 861 manual-wound chronograph but with the addition of a 12-hour GMT hand complication. The present lot, reference 145.013, represents a lesser-known variation with the calibre 910. The key difference is that the small seconds sub-dial has been replaced with a 24-hour AM/PM indication.

The particular example is very attractive and exceptionally well-preserved. The dial has acquired a desirable "tropical" patina, aging to a rich milk chocolate color at the registers. It is rare to find such a well-preserved model on the market, making it an opportunity not to be missed for collectors who seek to acquire this short-lived reference from Omega.
