The Complete Bremont Brand and Model Guide: Terra Nova, Supermarine, and Martin-Baker

The Short Answer

Bremont is a British watchmaker built by two brothers after a plane crash, and it makes three distinct tool-watch families worth knowing: the field-inspired Terra Nova, the dive-rated Supermarine, and the Martin-Baker MB line built for actual ejection-seat pilots. Prices run from about $3,050 for a basic Terra Nova 38 up to $6,950 for a full ceramic Supermarine.

Bremont builds in-house at its own manufacturing center in Henley-on-Thames, England, and every core-range watch carries COSC or ISO 3159 chronometer certification. This is a guide to the three collections that matter today, what happened to the brand's original ALT1 pilot chronographs, and where the real value sits.

Two Plane Crashes Built This Brand

Brothers Nick and Giles English founded Bremont in 2002. Their father Euan, a former RAF pilot with a PhD in aeronautical engineering, died in a flying accident in March 1995. Nick was badly injured, more than 30 broken bones, and returned to flying six months later alongside Giles anyway.

That gratitude became the company name. Bremont has leaned into aviation heritage ever since, most visibly through its long partnership with Martin-Baker, the British company that builds roughly 70 percent of the world's fighter ejection seats.

Built in England, Not Assembled There

Bremont relocated to a purpose-built Manufacturing and Technology Centre in Henley-on-Thames in 2021, after years of investing in in-house case and movement production. Every core-range Bremont watch carries COSC or ISO 3159 chronometer certification, a meaningful commitment for a brand this size.

New Ownership, Same Direction

Nick and Giles English no longer control the company they founded. Bill Ackman's Hellcat Acquisitions became Bremont's majority owner in 2023, and both brothers stepped down from the board in April 2025, staying on only as brand ambassadors. The English name still fronts the brand story, but the capital and the decisions now sit elsewhere.

The Terra Nova: Bremont's Everyday Range

Terra Nova is Bremont's field-watch family, built from 904L stainless steel and styled after early 20th century military pocket watches rather than any single vintage Bremont reference.

The Supermarine: Bremont's Dive Collection

Supermarine takes its name from the British aircraft manufacturer behind the Spitfire, and it is Bremont's water-rated range, built for actual diving rather than just poolside styling.

Supermarine Pricing and Depth Ratings

The core Supermarine 300M runs a 40mm 904L steel case at $3,550 to $4,400 depending on strap and date configuration, rated to 300 meters. A GMT version in the same case, limited to 500 pieces, adds a second time zone at $4,150 to $4,400. The Supermarine 500m steps up to a 43mm case rated to 500 meters at $4,700 to $5,000, and the Full Ceramic version, in either black or Polar White, tops the range at $6,450 to $6,950, with the white variant capped at 150 pieces.

Martin-Baker: The Watch Built for Ejected Pilots

The Bremont and Martin-Baker partnership started in 2007, with the first MBI watch released in 2009. That original MBI remains restricted to pilots who have actually used a Martin-Baker ejection seat to survive a real ejection, a genuinely rare qualification.

The MBII and MBIII, sold under the current Altitude MB Meteor naming, are open to any buyer. The 42mm titanium case runs $5,300 for a NATO or leather strap and $5,700 on the titanium bracelet, with special editions like the Felix the Cat and Stealth Grey variants priced from $6,450 to $6,850.

The Honest Trade-Off

Bremont's Martin-Baker story is real and well-documented, but it is also a story you are paying a premium for. A $5,300 to $6,850 titanium three-hander is not unusual pricing for the segment, yet it puts Bremont in direct competition with brands like Sinn and Oris that offer comparable specs, often with a longer independent service network and, in Sinn's case, a lower average price.

What Happened to the ALT1

Bremont's original ALT1 pilot chronographs, the ALT1-C and ALT1-P, were the watches that built the brand's early identity. Both are now officially retired from the current catalog. The ALT1-C ran a modified Calibre 13 1/4''' BE-50AV chronometer movement in a 43mm Trip-Tick steel case at $6,150, and the ALT1-P2 ran the related BE-53AE caliber at $4,995. Neither carried a GMT function despite the P-series name suggesting pilot-focused complexity.
