Bremont Supermarine Full Ceramic Polar White

Bremont has consistently carved its niche in the competitive landscape of performance timepieces by adhering to a core principle of creating exceptionally capable tool watches. Building upon this foundation and the recent successes with innovative materials, the British brand introduces a formidable new contender in its dive watch roster: the Supermarine Full Ceramic Polar White. This timepiece represents a calculated evolution, merging the celebrated design language of the Supermarine collection with the advanced material science of full ceramic construction, resulting in a watch that is as visually arresting as it is technically proficient.



The journey of Bremont, founded in 2002 by brothers Nick and Giles English, is one fueled by a passion for aviation, mechanics, and adventure. This heritage informs every piece that leaves their state-of-the-art manufacturing facility, "The Wing," nestled in the English countryside. The company's mantra, "Take It Further," is not merely a marketing slogan but a directive that dictates their engineering and design philosophy. Bremont watches are conceived as reliable instruments for individuals who push boundaries, whether in the air, on land, or at sea, and are subjected to rigorous testing that often involves military squadrons and world-class explorers.



The Supermarine collection itself has long been the cornerstone of Bremont's maritime offerings. Renowned for its robust build and serious diving credentials, the Supermarine is a trusted companion for underwater professionals and enthusiasts alike. This new release is a direct descendant of the popular Supermarine 500m Polar White edition, taking the crisp, legible aesthetic of its predecessor and encasing it in a cutting-edge material. The introduction of a full ceramic case, a technology Bremont has been refining, marks a significant step forward for the collection, demonstrating a commitment to enhancing performance through material innovation.



The creation of the watch's 43mm case is a testament to meticulous engineering and extreme manufacturing processes. The case is not simply coated in ceramic; it is crafted from a mono-block of the material. The process begins with a soft ceramic powder, which is carefully placed into a precision-engineered mould. This mould is intentionally oversized, creating a case blank that is 23% larger than the final product. This is where the true transformation occurs, through a high-pressure sintering process where the case is heated to an astonishing 1,450°C.



This extreme temperature, capable of melting most industrial metals, causes the ceramic particles to fuse and densify, shrinking the case by exactly 23% to its final, intended dimensions. Controlling this process is an exacting science, as even slight deviations in temperature could burn the color pigments and alter the desired tactical black hue. The result of this fiery ordeal is a watch case with immense structural integrity. The final step involves a sand-blasting treatment, which imparts a uniform, non-reflective matte finish, perfectly suited for a tool watch designed to minimize glare in demanding situations.



This high-tech ceramic case is complemented by a uni-directional bezel made from titanium, a material chosen for its high strength-to-weight ratio. The bezel itself features a knurled edge, providing excellent grip for operation with wet or gloved hands. Set within the titanium frame is a bezel insert also crafted from ceramic, this time in a polar white that matches the dial. This ensures a cohesive design and provides a scratch-resistant surface for the crucial 60-minute dive scale. The combination of black ceramic, PVD-treated titanium, and white ceramic creates a striking, modern, and highly functional assembly.



Engineered for the pressures of the deep, the watch boasts an impressive water resistance of 500 meters (50 ATM). This capability is secured by a robust screw-down crown and a helium escape valve. The latter is a feature essential for saturation divers, who spend extended periods in pressurized environments breathing a helium-rich gas mixture. During decompression, tiny helium atoms that have penetrated the watch can expand and potentially damage it; the one-way valve allows this trapped gas to escape safely, preserving the integrity of the watch.



Visually, the timepiece is defined by a powerful contrast. The deep, matte black of the full ceramic case serves as the perfect frame for the crisp, stark white dial. This "Polar White" dial is not a simple flat surface; it features a subtle yet intricate 3D wave pattern that adds a sense of depth and texture, evoking the maritime spirit of the Supermarine collection. This intricate detail catches the light in a dynamic way, ensuring the dial remains visually engaging.



Legibility, a non-negotiable attribute for any dive watch, is paramount in the design. Bold, applied trapezoid indexes mark the hours. These markers appear to flow directly from the bezel, creating a distinct visual effect reminiscent of a naval crosshair, which naturally draws the eye toward the center of the dial. This design choice is not merely aesthetic; it provides an immediate and intuitive way to read the time at a glance, a critical function in low-visibility underwater environments.



The hands are fashioned from polished Black Gold, their dark, reflective surfaces standing out sharply against the white dial. Both the applied indexes and the hour, minute, and second hands are generously filled with the latest generation of Super-LumiNova®. This high-performance phosphorescent material provides an intense and long-lasting blue emission, ensuring that the time is clearly visible in the darkest conditions, from a dimly lit room to the abyssal depths of the ocean.



Further enhancing the dial's functionality is a discreet date window positioned at the 3 o'clock mark, providing essential information without cluttering the clean layout. A subtle but significant detail is the presence of the Bremont "Wayfinder" compass logo, a symbol that reinforces the brand's dedication to exploration and adventure, serving as a constant reminder of the watch's purpose-built nature. A contrasting black dial ring with a printed minutes track frames the main dial, adding another layer of precision for timekeeping.



Driving the Supermarine Full Ceramic is the reliable Bremont Calibre BB14-AH automatic movement. This workhorse movement is built upon a foundation of proven components selected for their stability and durability. It features 25 jewels and operates at a frequency of 28,800 beats per hour (4Hz), a modern standard that contributes to its accuracy. The movement is equipped with a Glucydur balance wheel, an Anachron balance spring, and a Nivaflex mainspring—components known for their resistance to temperature changes and magnetism, ensuring consistent performance over time.



The movement also provides a healthy power reserve of 56 hours, meaning the watch can be set down for over two full days and will still be running when picked up again. This extended power reserve is a practical advantage for those who may not wear the same watch every single day. The entire movement is securely housed within a protective titanium container inside the ceramic case, providing an additional shock-absorbing buffer and further testament to the watch's robust, multi-layered construction.



Flipping the watch over reveals not a sapphire exhibition window, but a solid, PVD black titanium case back. This choice prioritizes durability and water resistance over a view of the movement, staying true to the watch's tool-watch ethos. The screw-in case back is intricately decorated with an engraving of a world map focused on the planet's oceans, a final, fitting tribute to the Supermarine's intended environment and its role as a global explorer's instrument.



The watch's physical presence on the wrist is considerable yet balanced. The 43mm case diameter and 50mm lug-to-lug length give it a modern, substantial feel, while the 13mm depth allows it to sit comfortably without being overly cumbersome. With a lug width of 22mm, it accommodates a variety of strap options. Remarkably, despite its robust build, the watch head itself weighs a mere 74 grams, a benefit of the advanced ceramic and titanium construction which makes it surprisingly comfortable for all-day wear.



Bremont offers this limited-edition model with two distinct strap choices, allowing the owner to tailor the watch's character to the occasion. The first option is a durable black rubber strap featuring a chevron pattern. This strap is ideal for water-based activities, offering resilience and comfort. It is fitted with a traditional pin buckle clasp and a convenient quick-release system, enabling swift and tool-free strap changes.



The second option is a black and grey woven fabric NATO-style strap. This strap has a unique heritage, as the fabric is meticulously woven on 18th-century Jacquard looms in France, adding a touch of historical craftsmanship to a modern timepiece. Its self-gripping fastening system is infinitely adjustable and provides a secure, comfortable fit, giving the watch a more tactical, field-ready appearance.



The credibility of such a high-performance watch is often solidified by those who rely on it in the most challenging conditions. Bremont ambassador Jimmy Chin, the world-renowned professional mountain athlete, National Geographic photographer, and Academy Award-winning filmmaker, embodies the spirit of the Supermarine Full Ceramic. His life's work at the nexus of extreme endurance and artistic precision—from pioneering first ascents to skiing Mount Everest—is a real-world test of any equipment he uses.



Chin's ability to move seamlessly between harsh mountain environments and the polished world of filmmaking mirrors the versatility of the Supermarine. It is designed to perform flawlessly under pressure, whether that pressure is measured in atmospheres underwater or in the high-stakes world of adventure documentary. His association with the watch is not just a partnership; it is a validation of its design philosophy.
