The Altitude Chronograph GMT is the ultimate pilot's tool watch — a mission-ready timepiece built for exploration, travel, and demanding environments.

The Altitude Chronograph GMT is the ultimate pilot's tool watch — a mission-ready timepiece built for exploration, travel, and demanding environments.

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.

"The spirit of British adventurers and explorers drives our mission to create the most capable tool watches"

Founded in 2002, Bremont is motivated by a relentless determination to create the world’s most capable tool watches. Crafted with precision and attention to detail, Bremont watches embody the unwavering spirit of the great British pioneers who dared to explore the unknown. Designed to excel in the depths of the ocean, the peaks of high mountains and the far extremities of the Earth’s surface, our watches are relied on by explorers, adventurers, and the military alike.

Designed around the principles of Air, Land and Sea, they are built to perform in any environment. Bremont watches are subjected to rugged use or exposed to harsh conditions and when it comes to reliable equipment, shortcuts cannot be taken. It is for this reason that they use the highest quality materials and watch making techniques available in the construction of Bremont timepieces.

Bremont proudly operates the only end-to-end watch manufacture in the UK. At ‘The Wing’ in Henley-on-Thames, they master the whole watchmaking process—from design and development to prototyping, assembly, testing, and servicing—ensuring the highest standards of quality throughout.
