Limited to 300 pieces, the HMAF Altitude 39 Date honours Bremont's partnership with His Majesty's Armed Forces. Featuring RAF blue accents, an anthracite dial and Air Force heraldic badge, it celebrates the heritage of military aviation.

The HMAF collection celebrates the capability, purpose and human endeavour embodied by the British Armed Forces, reflecting Bremont’s “Take It Further” philosophy. For 2026, the collection celebrates all three services with an Army Terra Nova field watch, a Naval Supermarine dive watch and an RAF Altitude pilot’s watch - each featuring the official heraldic insignia of its respective service.

The RAF is represented by the HMAF Altitude 39 Date, a three-hand pilot’s watch with date function and the RAF crest positioned at 6 o’clock. Drawing inspiration from the tones of vintage aircraft, the black dial is framed by a new midnight bronze Cerakote® case selected for its durability and scratch resistance. A bevelled crown ensures ease of use for a gloved hand.

As with all models in the Bremont Altitude collection, the watch carries design details from the iconic MB series. The Trip-Tick case construction, featuring a smooth black barrel, houses an anti-shock and anti-magnetic movement mount, while the seconds hand incorporates Bremont’s signature Martin-Baker ejection seat pull-cord detail in vintage bronze. Applied numerals, a white lollipop seconds hand and contrasting white minute markers on the dial flange further enhance legibility and reinforce the collection’s technical design language. Powered by a La Joux-Perret movement, the HMAF Altitude 39 Date delivers a 68-hour power reserve visible through an exhibition case back featuring the outlines of all three heraldic badges printed directly onto the sapphire crystal. A brushed tan nubuck strap with cream box stitching completes the retro-inspired execution. The HMAF collection is available as individual models, each limited to 300 pieces, or as a commemorative three-watch set, of which only 50 will be produced.

Bremont

"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.
