Bremont Supermarine Full Ceramic Deep Blue Takes on Iceland

If you’ve followed British watchmaker Bremont over the years, you already know the brand has specialized in tool watches from the start. The Henley-on-Thames manufacturer has tested watches in the air, on land, and deep beneath the ocean’s surface. The new Supermarine Full Ceramic Deep Blue marks the next chapter in its broader dive-watch story. More than a cosmetic update, it showcases advanced materials and elevates the collection with a robust, scratch-resistant ceramic case.

The Case

The manufacturing process behind crafting a ceramic case highlights how far Bremont is willing to push its engineering limits. The monobloc case begins as loose ceramic powder molded into a shape roughly 23 percent larger than the final product. It is then sintered at 1,450 degrees Celsius, causing the material to shrink to its exact dimensions. The result is a dense structure with a sandblasted matte finish. Bremont then uses a specialized laser tool to create the numerals and raised markings on the ceramic bezel insert. The finished case measures 43mm in diameter, 13mm thick, and 50mm from lug to lug.

Bremont pairs the blue ceramic exterior with a titanium inner case that houses the movement while keeping the watch light. This model boasts an impressive 500 meters of water resistance, ensuring it can survive depths far beyond recreational limits. A dedicated helium escape valve helps the watch withstand the pressures associated with saturation diving and decompression.

The Supermarine Full Ceramic Deep Blue also features a knurled titanium unidirectional bezel with a blue ceramic insert, plus a screw-down crown grooved for easy use, even with thick neoprene diving gloves. Every physical touchpoint on the case is designed with the user in mind.

The Dial

The black three-dimensional wave pattern on the dial is deeply cut, creating a miniature landscape of shadows and highlights that shifts each time the wrist moves. By choosing black gold plating for the hands, Bremont’s designers created a surface that feels sophisticated and stealthy in broad daylight. In the dark, the white Super-LumiNova on the hands and applied markers emits a vivid blue glow to match the ceramic exterior. The crosshair motif anchors the eye to the central axis when the wearer has only a moment to read the time.

Instead of relying solely on laboratory testing, Bremont also subjects its watches to real-world conditions. Explorer and former Royal Marines Commando Aldo Kane took the Supermarine Full Ceramic Deep Blue to Iceland, wearing it during dives in freezing glacial lakes and while crossing the country’s ice fields.

Moving from freezing air into icy water places considerable stress on a watch’s materials, seals, and movement. By ensuring that the ceramic, titanium, and sapphire components survived these harsh conditions, Bremont demonstrated the watch’s field-tested resilience.

The Movement

Inside the new Bremont Supermarine is the automatic BB64AH caliber, which uses the Sellita SW300-1A as its base architecture. Bremont chose this layout for its thin profile, then reworked it for field use. A Glucydur balance wheel helps maintain stable performance across temperature changes, while the Anachron balance spring and Nivaflex mainspring improve resistance to magnetism and support reliable timekeeping. The 56-hour power reserve keeps the watch running through a weekend off the wrist or while worn in rotation with other watches.

The movement sits beneath a blue PVD-coated titanium caseback engraved with a map of the world’s oceans. Selecting the right dive watch often comes down to balancing specifications with everyday wearability, and this reliable movement ensures the watch is ready to go when needed.

Wearability

This release marks the first time the British manufacturer has used blue ceramic for its Supermarine dive watch, and it offers three strap options. The quick-release black rubber strap provides a utilitarian look, while the black-and-blue woven NATO strap leans into the brand’s military heritage. For a slightly more elevated feel, the blue embossed rubber strap with a leather lining provides a sophisticated contrast to the technical case.

With production limited to 250 pieces worldwide, the Bremont Supermarine Full Ceramic Deep Blue offers a compelling alternative for collectors who want something other than a black-on-black diver. When you factor in the complexity of the ceramic case, the field testing in Iceland, and the upgraded internal components, it makes a strong case for itself at this price point.

For anyone hunting for a resilient daily timepiece built to handle a genuine outdoor expedition as easily as the office, Bremont’s latest release demands a closer look. The Supermarine Full Ceramic Deep Blue is priced at $7,400.
