Bremont Altitude MB Stealth Grey

Bremont introduces a new chapter in its storied partnership with Martin-Baker, the British engineering firm synonymous with aviation survival. The Altitude MB Meteor Stealth Grey emerges not with a shout, but with a quiet, confident presence. Limited to just 400 pieces globally, this timepiece is the latest evolution in the brand’s legacy of "stealth" editions, offering a monochromatic and highly technical take on their definitive pilot's watch. It is a watch born from a legacy of extreme testing and designed for absolute, uncompromising performance.



The foundation of the Altitude MB series rests on a unique and demanding collaboration. Martin-Baker is responsible for producing over 75% of the world's aircraft ejection seat technology, a field where failure is not an option. Bremont's partnership with them led to the creation of the MB line, watches that have been subjected to the same rigorous testing protocols as the ejection seats themselves. This includes live ejection tests, extreme temperature endurance, vibration, and salt fog trials. The result is a collection of timepieces with a proven and almost mythical level of durability, trusted by military pilots who depend on their equipment in the most critical moments.



At the heart of this collection is the exclusive MBI, a model available only to those who have personally survived a live ejection from an aircraft using a Martin-Baker seat. The Altitude MB Meteor Stealth Grey channels the DNA of that highly exclusive club, making its robust engineering and distinct design cues accessible to a wider audience of enthusiasts. It carries the weight of that heritage, promising a level of resilience that far exceeds the demands of daily life, built for those who appreciate engineering that has been proven at the edge of human endurance.



The immediate visual impact of the MB Meteor Stealth Grey is one of deliberate understatement. The watch is rendered almost entirely in a monochromatic, ultra-matt grey. This "Stealth Grey" finish is applied to a case crafted from Grade 2 titanium, a material chosen for its exceptional strength-to-weight ratio. The finish is not merely for aesthetics; it is functional, designed to absorb light and drastically reduce glare and reflection. This creates a low profile, evoking the radar-absorbent skins of stealth aircraft and naval vessels, where remaining unseen is a tactical advantage.



This muted canvas allows the watch's sculptural form to take center stage. Without the distraction of polished surfaces or high-contrast finishing, the eye is drawn to the clean lines, sharp angles, and purposeful curves of the case. It becomes a study in industrial design, where every element of its form is tied directly to its function. The absence of visual noise highlights the pure intent of the watch: to be an exceptionally capable and legible tool for timekeeping under any condition.



The case itself is a Bremont signature: the three-part Trip-Tick® construction. This design features a top case, a central barrel, and a case back, creating a robust and visually interesting structure. The MB Meteor Stealth Grey features a 42mm diameter with a lug-to-lug length of 49.3mm and a depth of 12.23mm. These dimensions, combined with a slimmed-down profile and reduced lug-to-lug distance, contribute to improved ergonomics and a comfortable presence on the wrist despite its rugged build.



A defining characteristic of the MB line is the knurled texture applied to the central case barrel, here finished in a tough black Diamond-Like Carbon (DLC). This tactile detail not only provides a visual break in the smooth titanium surfaces but also enhances grip, a nod to the practical, hands-on nature of military and aviation equipment. The texture carries over to the dual crowns, which are optimized for easy operation, even with gloves on.



Operation is managed through these two prominent crowns. The one at the 2 o'clock position controls the standard time-setting and winding functions of the movement. The crown at 4 o'clock is dedicated to operating the inner bi-directional rotating bezel. This internal bezel keeps the "glass box" sapphire crystal's profile clean while providing a crucial timing function. The action is governed by Bremont’s re-engineered Roto-Click® technology, ensuring each turn is met with a precise, satisfying click, preventing accidental adjustments and guaranteeing accuracy.



While the case is a masterclass in muted functionality, the dial presents a complex and deeply textural surprise. At first glance, it appears to be a simple, dark, and rugged surface. A closer look reveals an embossed pattern inspired by the cosmos. This intricate texture was created by meticulously scanning the surface of an actual meteorite and then stamping that unique, raw cosmic pattern onto a brass plate. The dial is then sealed with a durable, electro-applied finish, providing the resilience needed to perform in the field while offering a visual depth unlike anything else in the Bremont collection.



Legibility against this complex background is paramount. Bremont achieves this with large, applied Arabic numerals and indexes. Each marker is generously filled with high-grade white Super-LumiNova®, which emits a powerful blue glow in low-light conditions. This high-contrast application ensures that the time can be read with just a glance, whether in the dim light of a cockpit or the darkness of night. The gloss black hour and minute hands are treated with the same luminous material, standing out sharply against the meteorite-patterned dial.



Contrasting the overarching stealth theme are deliberate and meaningful flashes of color, drawn directly from the cockpit environment. The most prominent of these is the seconds hand. Rendered in a vibrant yellow, it is a direct homage to the MBI watch. The design features a lollipop-style red tip for precise reading and is counterbalanced by a looped tail that mimics the design of an ejection seat pull handle. This single element is a constant reminder of the watch’s life-saving heritage and its connection to Martin-Baker.



Further details reinforce this aviation DNA. A subtle red triangle sits at the heart of the dial, echoing the triangular "DANGER" warnings that appear on all Martin-Baker ejector seats. Encircling the date window at 3 o'clock is a dashed line, another detail reminiscent of the markings on military aircraft instrumentation. These carefully chosen accents serve as visual anchors, grounding the watch's contemporary aesthetic in its very real and very serious technical origins.



Powering the Altitude MB Meteor Stealth Grey is the Bremont BB14-AH automatic movement, which is built upon a reliable Le Joux Perret calibre. This robust engine features 24 jewels, operates at a frequency of 28,800 beats per hour (4Hz), and provides a substantial 68-hour power reserve. This extended power reserve means the watch can be set down for nearly three full days and will still be running accurately when picked back up.



True to its tool-watch mission, the movement is heavily protected from the rigors of the outside world. An innovative anti-shock system suspends the entire movement within a flexible rubber mount. This design effectively absorbs shocks and isolates the delicate components of the calibre from harsh impacts. This is a critical feature that has been proven through the violent forces of ejection testing.



Furthermore, the movement is shielded from the effects of magnetism, which can severely impact a mechanical watch's accuracy. A soft iron ring surrounds the movement, creating a protective barrier based on the principles of a Faraday Cage. This inner shield ensures precision and reliability are maintained even when exposed to the powerful magnetic fields present in modern environments, particularly within an aircraft cockpit.



For the first time in a stealth edition MB, the watch features a decorated titanium open case back. This provides a view of the BB14-AH movement, which has been finished in a gunmetal grey to match the watch's overall aesthetic. The custom Bremont rotor is visible, along with decorative Geneva Stripes on the bridges, showcasing a level of fine finishing that speaks to the craftsmanship within the rugged exterior.



The watch is presented on a matching ultra-matt Grade 2 titanium bracelet, completing the seamless, monochromatic silhouette. The bracelet is engineered for comfort and durability, featuring a smooth articulation that conforms easily to the wrist. It incorporates a secure butterfly clasp and, for modern convenience, a quick-release system. This allows the wearer to easily swap the bracelet for a strap without the need for tools, offering versatility while maintaining the watch's lightweight, performance-driven character. The weight of the watch head alone is a mere 53.29g, remarkably light for such a mechanically dense and durable timepiece.



The luminosity of the MB Meteor Stealth Grey is a standout feature. In daylight, the white Super-LumiNova® on the applied numerals, indexes, and hands provides a crisp, high-contrast display. As light fades, these elements come alive with a bright blue emission. This specific choice of color and high-grade material ensures optimal readability in the most challenging lighting conditions, a non-negotiable requirement for any serious pilot's watch.
