The Altitude 42mm Blue Dial Chronograph GMT is the ultimate pilot's tool watch — a mission-ready timepiece built for exploration, travel, and demanding environments.
The Altitude 42mm Chronograph GMT Blue Dial Bracelet 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 Blue Dial 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.
Trip-Tick Case Construction
Bremont’s signature Trip-Tick case construction, a reinforced three-part construction with a top case and case back sandwiching a smooth central barrel. The three-part design features a slimmed-down profile and reduced lug-to-lug distance for improved ergonomics.
Anti-shock & Anti-magnetic
Inside the case, the movement is suspended within a flexible rubber mount to absorb shocks and minimise impacts. Surrounding it, a soft iron ring provides anti-magnetic protection based on Faraday Cage principles — ensuring precision and reliability even in the most hostile environments.
Chronograph and GMT Functionality
The Altitude Chronograph GMT combines two essential functions for pilots and travellers alike – a precise chronograph and a second time zone display. The GMT hand is tipped with Bremont’s signature red arrow, while the running seconds subdial features a rotating tri-blade propeller motif, inspired by a Bremont military project.
Applied Stencil Design Numerals
The dial features applied stencil-style numerals and indexes, combining military-inspired design with modern clarity. Enhanced with the latest generation Super-LumiNova®, these elements ensure optimal legibility in low light.
Quick-Release 904L Steel Bracelet
For the Altitude Collection, Bremont introduces a new bracelet design, crafted in brushed 904L stainless steel for the Altitude Chronograph GMT. Featuring quick-release functionality and engineered for maximum flexibility, it is secured with curved bars that enable smooth articulation and exceptional comfort.
Chronometer-Rated BC781 Automatic Movement
The Altitude Chronograph GMT is powered by the chronometer-rated BC781 automatic movement, delivering a 62-hour power reserve alongside precise chronograph and GMT functionality. Finished in gunmetal grey with Geneva Stripes, the movement is visible through an open case-back.
