Product overview

Everything worth knowing.

A detailed, evidence-led view of the product—not a generic sales summary.

The Altitude Chronograph GMT is the ultimate evolution of Bremont’s aviation tool watch — combining the proven resilience of the MB series with the added functionality of a chronograph and GMT complication. Housed in a 42mm Trip-Tick case made from ultra-rugged 904L stainless steel, with a black DLC-coated centre barrel, the watch has been engineered to withstand the harshest conditions. Inside, the chronometer-rated BC781 movement delivers a 62-hour power reserve and features a quick-set date, hacking seconds, and independent GMT hand. Beneath the surface, the automatic movement is suspended within a flexible rubber mount to absorb shocks and minimise impacts. The Altitude Chronograph GMT has an open case-back, revealing the movement’s fine finishing in gunmetal grey with Geneva Stripes. The open case-back retains the anti-magnetic shielding, which is provided by a soft iron ring around the movement, based on Faraday Cage principles. The dial design is clean, legible, and cockpit-inspired, with applied Super-LumiNova® numerals and indexes, and recessed chronograph subdials. A red-tipped GMT hand tracks a second time zone against a 24-hour day/night scale, while the rotating seconds subdial at 9 o’clock takes the form of a tri-blade propeller — a nod to a Bremont military project. For the Altitude Chronograph GMT, Bremont introduces a new bracelet design, crafted in brushed 904L stainless steel. Featuring quick-release functionality and engineered for maximum flexibility, it is secured with curved bars that enable smooth articulation and exceptional comfort. Verified details include bracelet material of Stainless Steel, brand collections of ALT-1, dial colour of Black, diameter of 42mm, guarantee of Bremont 3 Year Guarantee and movement of Automatic. Available colours: Black.
