Omega FlightMaster GMT Chronograph

WOW! An Original Historically Significant Omega FlightMaster GMT Chronograph The Flightmaster c.911 (ST145.036) uses the c.861 base Omega manual-wind movement with a 12-Hour GMT hand complication. The hand moves and is set uni-directionally via the auxiliary crown located at 10 o'clock on the case. The crown located @ 8:30 on the case set's the under mineral crystal bezel. Originally from the Omega factory in Bienne, Switzerland, the Auxillary Crowns on the left side of the case (above left) have a circular indentation in them and are color coded to their function... Blue for the second hour hand, black for the under crystal bezel. Over time this paint can flake out or due to replacement with a conventional crown, not appear at all. In addition, the pushers on the right side of the watch (above right) also have indentations on them as well and have yellow/orange paint on them. These are color-keyed to the sub-register hands that indicate chronograph elapsed time. Like the auxillary crowns the paint can flake and on many examples have been replaced with plain pushers... This color coding is consistant through out the Flightmaster line as shipped from the factory. Watches with paint and original crowns/pushers intact are worth more than a Flightmaster in otherwise comparable condition without... Aside from this the operation of the watch is the same as the moonwatch with a similar power reserve, etc. WR rating from the factory is 60 meters according to sales literature of the era. This is in no small part due to the use of a mineral glass crystal instead of a plastic crystal on the moonwatch. Dimensions: Length: 52.25mm Width w/ Crown: 45.55mm Width w/o Crown: 42.6mm Thickness: 15.65mm Condition: This Watch appears to be in unaltered, ORIGINAL CONDITION. The Flightmaster was released in 1969; it was designed for pilots. The inner bezel can be rotated in either direction using the crown at 8:30. The blue GMT hand can be adjusted from the crown at 10:00 (this crown is operational but if you pull it out the crown will come off completely, the stem is broken). The watch keeps time and all original operations are fully functional. The crystal gasket has not aged well; you can see a slightly uneven black residue at under the edge of the crystal. The crystal shows wear with scratching throughout. The dial is in EXCELLENT condition. Everything on the watch is believed to be original. Original bracelet. Original box and hanging tag, with original directions for use. History This watch was originally a graduation gift and owned by the same individual until January 2015.
