Bremont

Altitude Chronograph GMT 42mm Bracelet Watch

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.
