With the launch of the Altitude Collection, evolved from its celebrated MB aviation watches, Bremont is cementing it’s mission to craft the finest timepieces for Air, Land and Sea, mixing modern British elegance with durability, and style.
At the pinnacle of the collection stands the Altitude Perpetual Calendar GMT Mono- pusher. Limited to 50 pieces, cased in lightweight titanium, both dials and case- barrels in evocative ‘Air Force Blue’, adding the enduring finesse of high horology to the Altitude family’s rugged, MB-inspired DNA.
Built for those who demand refinement, resilience and practicality, the Altitude Perpetual Calendar GMT Mono-pusher unites two legendary complications in one supremely robust, perfectly engineered timepiece, with a complication module exclusively devised by Agenhor, the celebrated Geneva atelier.
PERPETUAL PERFORMANCE
Bremont’s design team faced a key challenge: integrating a Perpetual Calendar with a GMT without compromising the Altitude Collection’s aviation-inspired sportiness, everyday usability, and visual clarity. Their solution was an ingeniously efficient display, which presents complex information with exceptional readability, while preserving the distinctive design language and durability of the Altitude range.
The 42mm case, made of lightweight grade 2 titanium, features the collection’s signature three-piece Trip-Tick case construction.
For the GMT, a domed disc at 12 o’clock with a globe decoration – echoing that previously seen in 2024’s Terra Nova Dual-Time Tourbillon – provides the second time-zone indication: as the globe turns, an arrow indicates the home time against a 24-hour index that’s divided into day and night sections. Adjusting this is straightforward: a mono-pusher integrated into the crown allows the wearer to advance the arrow in one-hour increments. A corrector at 2 o’clock allows you to set the date, whilst a corrector positioned at 4 o’clock allows you to set the leap year and month.
At 9 o’clock, running seconds is displayed with a two-blade ‘propeller’ hand, on a sector-style subdial with Bremont’s Wayfinder logo at its centre.
The perpetual calendar’s indications – date, month and position in the leap year cycle – are presented on the other two subdials, at 3 o’clock and 6 o’clock respectively.
At 6 o’clock, a pointer indicates the date on a circumferential index. At the 3 o’clock position, a beautifully intuitive month/year indication uses a four-blade propeller- style hand, with three white-tipped blades and one red-tipped blade.
The subdial is divided into four sectors, each representing a year in the leap cycle, while the first sector also includes markings for the 12 months. The red-tipped blade denotes the current position in the four-year cycle, while the month is shown by whichever of the four blades is passing through the first sector at any given time. The propeller’s movement is imperceptible, advancing in 172 micro-jumps across the four-year cycle – a shift of just under 2.1 degrees every eight days.
ENGINEERED FOR ADVENTURE
To realise this dynamic and highly unusual combination, Bremont worked with Agenhor, one of Switzerland’s most lauded horological ateliers; and with Sellita, a leading movement manufacturer.
Founded in 1996 by horological visionary Jean-Marc Wiederrecht and now led by his sons, Laurent and Nicolas, Agenhor has earned numerous accolades for its groundbreaking innovations, featured in timepieces from esteemed brands such as MB&F, H. Moser & Cie, and Hermes.
Exclusively for Bremont, Agenhor has devised a slim and highly economical module integrating the perpetual calendar and GMT functions, which offers ease in operation, whilst meeting the Altitude Collection’s stringent requirements for endurance and dependability.
“The combination of a perpetual calendar and GMT function is extremely rare in watchmaking, but for Bremont it gives us the perfect mix of classical sophistication and adventurousness. We love the idea that it’s quite unusual but also really useful,” says Bremont CEO Davide Cerrato. “But it had to be as robust as any of the Altitude watches, easy to use, and present a durable, sporty execution of a Perpetual Calendar GMT – it’s intended as an everyday watch, not a delicate item that lives in the safe. That was our brief to Agenhor, who I think are amongst the best specialists working in Switzerland today.”
At the heart of the watch is a manually wound base calibre from Sellita, the AMT6900. This is crafted within Sellita’s top-tier, custom-build AMT (Atelier Manufacture Technique) programme, and designed to the highest standards of precision and finishing. The baseplate and bridges, designed with graceful symmetry, display a ‘soleillage courbe’ – or curved sunray – finish, contrasting with polished screw-heads and wheels that combine snailed and polished finishing. The Bremont ‘Wayfinder’ logo is laser engraved on the ratchet wheel. The entire mechanism, consisting of both the base movement and the complication module, stands at just 6.8mm thick, keeping the entire watch to a highly wearable 12.65mm thick. Finally, the movement features a Côte de Genève finish and an engraved Bremont logo with a ruthenium treatment.
Thanks to its fine engineering, the Altitude Perpetual Calendar GMT Mono-pusher delivers a power reserve of 50 hours. This ensures the unwavering performance of a complex wristwatch conceived to endure decades – if not centuries – of usage.
AERIAL ELEGANCE
The Altitude Perpetual GMT combines this innovative functionality with true elegance, following the aviation-inspired design codes of the Altitude Collection. The dial is in ‘Air Force Blue’ – also known in Italy as ‘blu aviazione’ – a richly nuanced shade long associated with aviation, and inspired by the blue-grey uniforms of Britain’s Royal Air Force. This has been given a smart vertically brushed finish, reminiscent of mid-Century vintage watches, which provides a rich contrast with the black tonality of the chapter ring and date sub-dial. The Air Force Blue is repeated in the brushed PVD coating of the centre barrel of the Trip-Tick case, standing out from the titanium top and bottom sections.
As a watch designed for everyday wear, both comfort and ease of operation are critical factors. Along with the crown-based mono-pusher for adjusting the GMT, recessed correctors at 2 and 4 o’clock allow for effortless adjustments of the calendar functions while maintaining a streamlined case profile, without the need for more complex intervention.
With only 50 pieces available, the Altitude Perpetual Calendar GMT introduces a dynamic and exciting new chapter in Bremont’s aviation lineage. Priced at £33,500, it delivers exceptional value in the realm of high complications, while offering rarity, ingenuity and masterful craftsmanship in a supremely wearable and accessible aviation tool watch.
INTRODUCING A NEW ERA IN BREMONT AVIATION WATCHES
Since Bremont was founded in 2002, the drama and wonder of aviation have been at the heart of its story, and of its products. Its pilot’s watches, robustly engineered and rooted in aviation heritage, have earned the trust of military and civilian fliers, adventurers, collectors and enthusiasts. None more so than the MB series, specifically designed to withstand the punishing procedures used in testing aircraft ejection seats.
In 2025, Bremont proudly builds on this legacy by introducing new models into the Altitude Collection, comprised of high-performance pilot’s watches that extend the redoubtable qualities and style of the MB. The Altitude collection, alongside the Terra Nova and Supermarine collections embody Bremont’s mission to create supremely capable tool watches for air, land and sea.
At the forefront of the new introductions for 2025 is the Altitude MB Meteor, a dynamic new iteration of the MB concept: refined, upgraded and streamlined, while retaining the features that have defined celebrated MB models for 16 years.
Complementing this flagship model, the Altitude 39 Date and the Altitude Chronograph GMT are built on the characteristics of extreme durability, shock resistance and anti-magnetism while broadening the collection’s, utility, flair and appeal.
Enhanced with cutting-edge materials, new movements and sophisticated bracelets, these new introductions to the Altitude Collection embody Bremont’s enduring commitment to crafting durable modern watches of exceptional capability and design.
“This year we’re returning to our heritage and celebrating what makes our brand unique. Our DNA is deeply rooted in aviation, a passion that continues to fuel our evolution. This is reinforced by the tenacity of the materials we use and the introduction of new exciting new complications to enhance and further develop the Altitude collection” comments Davide Cerrato, CEO.
THE LEGENDARY BREMONT MB
In 2007 Martin-Baker, the British-based world-leader aircraft ejector seat design and manufacturer, challenged Bremont to develop a pilot’s watch capable of withstanding the extreme forces of its seat testing programme. That meant enduring live ejection testing at forces exceeding 20 Gs, extreme temperature swings from -40°C to +40°C, and dynamic crash tests. It also had to withstand violent vibrations replicating 30 years of an aircraft’s service life, rapid descent simulation from 100,000 feet in an altitude chamber, and prolonged exposure to corrosive salt fog and intense humidity.
Bremont’s answer was the MB (for ‘Martin-Baker’): a watch featuring the brand’s Trip-Tick case construction with an iconic three-part design, in which the top and bottom sandwich a knurled central barrel. Inside this capsule, a rubberised, anti- shock movement mount and anti-magnetic inner ring provided ultimate protection for the movement.
Famously, the MBI model was reserved exclusively for those who have experienced the reality of ejecting from an aircraft – as it still is. But its civilian counterparts, the MBII and (with a GMT) the MBIII, quickly became enduring favourites in the Bremont line-up, distinguished by their dual crowns, innovative case design, bi-directional Roto-Click inner bezel and seconds hand counterbalanced with a looped feature inspired by the pull-handle of an ejector seat. Spearheading numerous partnerships with military units worldwide, the MB line became defining pillar of the Bremont story.
With the Altitude Collection, Bremont is now building on this legacy, and taking this revered aviation tool to new heights of sophistication, performance and durability.
THE ALTITUDE MB METEOR
The most significant evolution of the MB concept to date takes its name from the Gloster Meteor, Britain’s very first jet fighter, and the aircraft used for Martin-Baker’s original live ejection test in 1946. Remarkably, two Gloster Meteors are kept by the company today, and are still used for live ejection testing.
The MB Meteor integrates frontline materials, improved ergonomics, and significant technical advancements into the MB’s dual-crown, Trip-Tick format.
Its 42mm case highlights the handsome, flowing lines of the three-part Trip-Tick design, now gently refined with a slimmer profile and reduced lug-to-lug distance, to sit perfectly on the wrist. The entire case is made in Grade 2 titanium, dramatically reducing weight while increasing durability.
This includes an iconic central barrel, originally made in anodized aluminium, with knurled titanium options in black or titanium grey with future releases to feature additional colours. A new, concave, angled bezel profile is now paired with a ‘glassbox’ sapphire crystal, striking a deft balance between modern refinement and vintage-inspired elegance.
The dual crowns – one at 2 o’clock for winding and setting, and one at 4 o’clock for operating the bi-directional inner bezel – have been optimised for ergonomics and utility, delivering a much smoother operation. The inner bezel’s Roto-Click technology has also been re-engineered, ensuring effortless and precise action with the pure, satisfying click familiar to MB owners.
This frames a dial rigorously designed for enhanced legibility, with options available in both black and brushed silver iterations. Applied numerals and indexes, along with the use of high-grade Super-LumiNova, ensure optimal visibility and clarity. The watch retains one of the MB’s most iconic features: the ‘lollipop’ seconds hand counterbalanced by a looped ‘ejection’ pull handle in white and black stripes. This has inspired new details also redolent of a military aircraft cockpit: a stencilled motif for the numerals, and a dashed line around the date window. As before, the red triangle at the heart of the dial echoes the triangular “DANGER” warning that appears on all ejector seats.
Beneath the surface, the MB line’s core endurance features once again ensure absolute toughness. The movement is suspended within a flexible rubber mount to absorb shocks and minimise impacts, while soft-iron shielding protects against powerful magnetic fields.
The MB Meteor is powered by the exceptional BB14, based on the G100 automatic movement from the specialist Swiss manufacture La Joux-Perret, which delivers a 68-hour power reserve. The MB Meteor has an open case-back, revealing the movement’s fine finishing in gunmetal grey with Geneva Stripes. Anti-magnetic shielding is provided by a soft iron ring around the movement, based on Faraday Cage principle.
For the MB Meteor, Bremont introduces a new bracelet design, crafted in brushed titanium. Featuring quick-release functionality and engineered for maximum flexibility, it is secured with curved bars that enable smooth articulation and exceptional comfort.
The MB Meteor is also available on a new, textured leather strap or an artisanal, Bremont NATO strap.
ALTITUDE 39 DATE
The MB format reinterpreted as an ultra-durable tool watch for everyday wear. The dial language, case contours and impervious engineering of the MB, now incorporated in a streamlined timepiece ideal for all situations.
The 39mm Trip-Tick case, featuring a single crown, is crafted from high-grade 904L stainless steel, meaning superior corrosion resistance and strength, with a centre barrel in black DLC-coated stainless steel. The highly reliable BB14 calibre is again used, protected as ever by a shock-absorbing inner mounting and anti- magnetic shielding.
ALTITUDE CHRONOGRAPH GMT
Purposeful, bold, and deeply rooted in aviation, watches combining chronograph and GMT functionality have long been a staple of Bremont’s lineup, as well as playing a key role in some of Bremont’s most successful military collaborations. As such, it was always going to be an essential part of the new Altitude collection.
For the 42mm Altitude Chronograph GMT, despite the functional complexity born from two significant complications and multiple read-outs, legibility and ease of use remain paramount. Combined with the hardiness and dependability that unites all the Altitude watches, this makes for a mission-ready timepiece that’s purpose built for exploration, travel and demanding environments.
The Trip-Tick case is made from ultra-rugged 904L stainless steel, with a black DLC-coated centre barrel. Inside, the watch is powered by the chronometer- rated BC781 automatic movement, with a 62 -hour power reserve, quick-set date and GMT, and hacking seconds. As with all Altitude watches, the movement is suspended in a rubberised, shock-absorbing mounting, and ringed with soft iron anti-magnetic shielding.
The military-inspired dial layout uses applied numerals and indexes, with high-grade Super-LumiNnova, to ensure utmost legibility, with deft twists that characterise Bremont’s detail-oriented design. The GMT hand is tipped with Bremont’s signature red arrow, read against a 24-hour day/night ring, while the running seconds display, denoted by a rotating tri-blade propeller motif, was inspired by a Bremont military project. This is also the first time that Bremont’s Wayfinder logo has appeared at 3 o’clock on a dial.
The Altitude Chronograph GMT is available comes with either a black dial, or in brushed silver with contrast finish for the chronograph subdials. It is available on the quick-release Altitude bracelet, on a nubuck leather strap or on a NATO strap.
