Since its inception in 2002, Bremont has carved a distinct niche within the watch industry, heavily influenced by the founders' passion for aviation and engineering. Their pilot's watches, known for robust construction and a clear link to aviation history, have gained respect among professionals, adventurers, and watch enthusiasts alike. Central to this reputation is the MB series, watches born from a unique collaboration and designed to survive the rigors of ejection seat testing. Now, Bremont expands on this foundation with the introduction of the Altitude Collection for 2025, featuring three new models that refine and enhance the core MB principles for a new era.



The story of Bremont is intertwined with the skies. The brand's commitment to creating exceptionally durable timepieces stems from a deep appreciation for mechanical engineering and the demanding environments faced by aviators. This focus led to a pivotal moment in 2007 when Martin-Baker, the British leader in ejection seat technology, approached Bremont with a formidable challenge: create a watch that could withstand their incredibly harsh testing procedures. This wasn't merely about looking the part; it was about genuine, measurable resilience.

The challenge laid down by Martin-Baker was extreme. The proposed watch needed to survive the violent forces of live ejection tests, which can exceed 20 Gs. It had to function flawlessly through drastic temperature fluctuations, from a biting -40°C to a scorching +40°C. Furthermore, the watch had to endure dynamic crash simulations, vibrations mimicking 30 years of aircraft service life, rapid decompression tests simulating descents from 100,000 feet, and prolonged exposure to corrosive salt fog and high humidity. Failure was not an option for a device intended for pilots relying on life-saving equipment.



Bremont rose to the occasion, developing the original MB (Martin-Baker) watch. This timepiece introduced key Bremont technologies, including the signature Trip-Tick case construction. This three-part design features a distinct top bezel section, a case back, and a separate, often contrasting, central barrel, typically characterized by a knurled pattern for grip. Inside this protective shell, Bremont incorporated a specially designed rubberized movement mount to absorb shocks and an anti-magnetic soft-iron inner ring (Faraday cage principle) to shield the delicate mechanics from disruptive magnetic fields.



The resulting MB watch proved its mettle, passing Martin-Baker's tests. A unique tradition began with the MBI model, available exclusively to individuals who have actually ejected from an aircraft using a Martin-Baker seat – a true badge of honor. Its civilian counterparts, the MBII (time and date) and MBIII (adding a GMT function), quickly became pillars of the Bremont catalogue. These models were easily recognizable by their dual crowns (one for time setting, one for the internal rotating bezel), the innovative Roto-Click bezel mechanism offering precise, tactile feedback, and the distinctive seconds hand with its looped counterweight inspired by the yellow-and-black pull handle of an ejection seat. The MB line solidified Bremont's reputation and led to numerous collaborations with military units worldwide.



Building upon this robust heritage, Bremont introduces the Altitude Collection in 2025. This new range represents a significant evolution, taking the proven capabilities and distinct style of the MB series to new levels of performance and refinement. The collection launches with three core models: the Altitude MB Meteor, the Altitude 39 Date, and the Altitude Chronograph GMT. According to Bremont CEO Davide Cerrato, "This year we’re returning to our heritage and celebrating what makes our brand unique. Our DNA is deeply rooted in aviation... 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.” These watches, alongside the existing Terra Nova (Land) and Supermarine (Sea) collections, underscore Bremont's focus on creating highly capable tool watches for any environment.



Leading the charge is the Altitude MB Meteor, presented as the most advanced iteration of the MB concept yet. Its name pays homage to the Gloster Meteor, Britain's first operational jet fighter, which was crucially used by Martin-Baker for their initial live ejection tests back in 1946. Demonstrating the aircraft's enduring utility, Martin-Baker still maintains and uses two Gloster Meteors for testing today. The watch aims to integrate cutting-edge materials and technical upgrades into the familiar MB format.

The MB Meteor features a 42mm case crafted entirely from Grade 2 titanium. This choice significantly reduces the watch's weight compared to steel, enhancing comfort without sacrificing strength. The three-part Trip-Tick case construction sees refinements, including a subtly slimmer profile and a reduced lug-to-lug measurement, allowing the watch to sit more comfortably on a wider range of wrists. The characteristic knurled central barrel is also rendered in titanium, offered initially in black or titanium grey options, with Bremont hinting at future color variations. A newly designed concave, angled bezel profile meets a 'glassbox' sapphire crystal, adding a touch of vintage aesthetic to the modern tool watch design.



Ergonomics receive specific attention in the MB Meteor's design. The dual crowns – located at 2 o'clock for winding the movement and setting the time/date, and at 4 o'clock for operating the internal bi-directional bezel – have been redesigned for smoother, more intuitive operation. The Roto-Click mechanism within the inner bezel, a hallmark of the MB series providing distinct clicks for each position, has also been re-engineered for an even more precise and satisfying tactile experience, ensuring effortless adjustments.



Legibility, a critical factor for any pilot's watch, is paramount in the MB Meteor's dial design, available in either black or a sophisticated brushed silver finish. Applied numerals and indexes are generously filled with high-grade Super-LumiNova for clear visibility in low-light conditions. The watch proudly retains the iconic MB seconds hand: a sleek hand terminating in a 'lollipop' tip, counterbalanced by the unique loop resembling the ejection seat pull handle, rendered here in black and white stripes. This aviation theme inspires further details, such as a subtle stencilled look for the numerals and a dashed-line graphic framing the date window at 3 o'clock. The small red triangle positioned below the Bremont logo at 12 o'clock serves as a nod to the triangular "DANGER EJECTION SEAT" warnings found in military cockpits.



Internally, the MB Meteor houses the BB14 automatic movement. This calibre is based on the G100 movement produced by the respected Swiss specialist manufacturer La Joux-Perret. It offers a substantial 68-hour power reserve, meaning the watch can be taken off for a weekend and still be running on Monday morning. True to its MB lineage, the movement is protected by Bremont's anti-shock flexible rubber mount and the soft-iron anti-magnetic inner ring. A notable update is the inclusion of an open case-back, allowing a view of the BB14 movement, which features a custom Bremont rotor finished in gunmetal grey with decorative Geneva Stripes. Despite the display back, Bremont ensures the anti-magnetic shielding remains effective via the encompassing soft iron ring.



Complementing the MB Meteor is a newly designed bracelet, crafted from brushed titanium to match the case material. This bracelet incorporates a quick-release system, allowing for easy strap changes without tools. Engineered for flexibility, it utilizes curved link bars to ensure smooth articulation and comfortable wear against the wrist. For those preferring straps, the MB Meteor is also offered on a new textured leather strap or a durable, high-quality Bremont NATO strap.

For wearers seeking the MB aesthetic and robustness in a more compact and streamlined package, Bremont offers the Altitude 39 Date. This model reinterprets the core MB design principles for everyday versatility. It features a 39mm diameter case, making it suitable for a broader range of wrist sizes and preferences for less imposing watches. The case retains the Trip-Tick construction but utilizes high-grade 904L stainless steel, known for its superior corrosion resistance compared to the more common 316L steel, paired with a contrasting black DLC (Diamond-Like Carbon) coated stainless steel center barrel for a sleek, modern look. This model simplifies the design with a single crown at the traditional 3 o'clock position for time and date setting.



Despite its more dress-oriented dimensions, the Altitude 39 Date does not compromise on durability. It incorporates the same protective features found in its larger sibling: the flexible anti-shock movement mount and the soft-iron anti-magnetic inner ring. The dial design prioritizes clarity and legibility, available in black or brushed steel variants. It features applied indexes filled with Super-LumiNova and retains the signature MB 'lollipop' seconds hand with the ejection pull handle counterweight, maintaining a clear visual link to its aviation tool watch heritage. The date window is positioned at 3 o’clock.



Powering the Altitude 39 Date is the same reliable BB14 automatic movement found in the MB Meteor, delivering the practical 68-hour power reserve. Like the Meteor, it features an open case-back displaying the movement's finishing, while still ensuring protection against magnetic fields and shocks. This combination of a more restrained size with robust internal engineering makes the Altitude 39 Date a compelling option for those wanting a durable, everyday watch with distinct aviation DNA.



The Altitude 39 Date is available with strap and bracelet options suited to its design. Buyers can choose a new bracelet crafted from matching brushed 904L stainless steel, which presumably features the same quick-release functionality and comfort-focused engineering as the titanium version on the MB Meteor. Alternatively, it is offered on a black nubuck leather strap featuring contrasting white box-stitching, lending it a slightly more casual yet refined appearance.

Rounding out the initial Altitude Collection launch is the Altitude Chronograph GMT. This model represents the pinnacle of functional complexity within the new range, combining the established toughness of the MB line with both a chronograph complication for measuring elapsed time and a GMT function for tracking a second time zone. Bremont has a history of creating watches with this combination, often utilized in successful military collaboration pieces, making it a natural fit for the Altitude lineup. It’s positioned as a mission-ready tool watch built for exploration, travel, and demanding use.



The Altitude Chronograph GMT is housed in a 42mm Trip-Tick case constructed from robust 904L stainless steel, featuring a black DLC-coated stainless steel center barrel similar to the 39 Date. Despite the added complexity of the chronograph and GMT functions, Bremont emphasizes legibility and ease of use. Powering the watch is the BC781 automatic movement, which is chronometer-rated to ISO 3159 standards, guaranteeing a high level of timekeeping accuracy. This movement provides a 62-hour power reserve, features quick-set functionality for both the date and the independent GMT hand, and includes hacking seconds for precise time setting. Naturally, it benefits from the standard Altitude collection protection: the rubberized anti-shock mount and the soft-iron anti-magnetic shield, viewable through an open case back.



The dial layout of the Chronograph GMT draws inspiration from military instruments, ensuring clarity despite the multiple indications. Available in black or brushed silver (with contrast-finished chronograph sub-dials on the silver version), it employs applied numerals and indexes filled with Super-LumiNova. Several details add Bremont character: the GMT hand, tracking a second time zone against an internal 24-hour day/night scale ring, is tipped with Bremont’s signature red arrow motif. The running seconds indicator, located in the sub-dial at 9 o'clock, takes the form of a continuously rotating tri-blade propeller design – a feature inspired by a previous Bremont military project. Additionally, this model marks the first appearance of Bremont's Wayfinder logo on the dial, positioned within the date aperture at the 6 o'clock sub-dial. The chronograph functions include a central sweep seconds hand, a 30-minute counter at 12 o'clock, and a 12-hour counter integrated with the date at 6 o'clock.



The Altitude Chronograph GMT offers versatility in wear, available on the new quick-release Altitude bracelet (in 904L stainless steel), a black nubuck leather strap with white stitching, or a black and anthracite Bremont NATO strap. This range of options allows users to tailor the watch's look and feel to different situations, from professional settings to rugged adventures.



Bremont's connection with military aviation isn't just historical inspiration; it's an ongoing reality. Since providing a bespoke MBII for the US Navy’s Sunliners squadron in 2011, the brand has created specialized timepieces for over 500 military groups globally, encompassing air squadrons, infantry units, naval crews, and special forces. This experience working closely with personnel who rely on their equipment in critical situations informs the design and engineering of their watches. Bremont proudly holds the title of official luxury watch partner to His Majesty’s Armed Forces, creating timepieces built for purpose and trusted in action.
