The Omega Flightmaster is one of the most ambitious and technically complex timepieces ever produced by the Maison, designed specifically for the needs of international pilots during the "Golden Age" of jet travel. The Reference 145.026 represents the second generation of this legendary "pilot's tool," introducing the improved Calibre 911 which replaced the 24-hour indicator of its predecessor with a more practical running seconds sub-dial. Its massive 43mm "pilot" case is a masterclass in ergonomic industrial design, housing no fewer than five crowns and pushers. This "control center" allows the wearer to operate a chronograph, an internal rotating bezel for flight timing, and a secondary GMT hand for tracking a second time zone. Notably favored by Concorde crews and Soviet Cosmonauts alike, the Flightmaster is a definitive icon of 1970s functionalism. Brand: Omega Model: Flightmaster Reference: 145.026 Year: Circa 1971–1973 Movement: Manual-wind Chronograph (Calibre 911) Case Diameter: 43 mm (excluding crowns) Case Material: Stainless Steel Bracelet: Stainless Steel (Reference 1162/172) Dial: Matte Grey with tri-color hands and internal rotating bezel Glass: Flat Mineral Crystal Functions: Chronograph, Dual Time (GMT), Running Seconds, Internal Bezel Box/Papers: Not included A true centerpiece for any Omega enthusiast, the Flightmaster 145.026 is prized for its high-contrast "cockpit" aesthetic and its direct connection to the Apollo-Soyuz era of space exploration. Unlike many chronographs of the era, the Flightmaster was built from the ground up as a professional instrument, evidenced by the color-coded crown inserts that match the hands they control. Its imposing wrist presence and mechanical sophistication make it a standout lot on the Catawiki platform, representing a period where Omega pushed the absolute boundaries of tool-watch engineering.
