The Altitude Chronograph GMT is the ultimate evolution of Bremont’s aviation tool watch, uniting the proven resilience of the MB series with the precision of a chronograph and the versatility of an independent GMT complication. Designed for pilots and professionals, it delivers uncompromising performance across time zones.
The 42mm Trip-Tick® case, machined from ultra-rugged 904L stainless steel with a black DLC-coated centre barrel, is engineered to withstand extreme conditions. Inside, the chronometer-rated BC781 automatic movement provides a 62-hour power reserve, quick-set date, hacking seconds and an independent GMT hand. The movement is suspended within a flexible rubber mount to absorb shocks, while anti-magnetic protection is ensured by a soft iron Faraday ring — all visible through an open case-back finished in gunmetal grey with Geneva Stripes.
The cockpit-inspired dial prioritises clarity and control. Applied Super-LumiNova® numerals and indexes deliver excellent low-light legibility, while recessed chronograph subdials maintain balance and depth. A red-tipped GMT hand tracks a second time zone against a 24-hour day/night scale, and the rotating seconds subdial at 9 o’clock features a distinctive tri-blade propeller design, a purposeful nod to Bremont’s military heritage.
