Bremont's 500m ceramic dive watch arrives in deep blue for 250 buyers

Bremont has added a fourth colorway to its Supermarine Full Ceramic collection with the Deep Blue, limited to 250 pieces and priced at €7,750. The announcement came on October 8, 2026, and the watch joins Polar White, Jungle Green and the non-limited Tactical Black launched since the series debuted in 2024.

The Deep Blue reuses the series' full specification rather than changing the watch. The 43mm case stands 13mm tall and measures 50mm lug-to-lug, yet the entire head weighs just 74 grams thanks to its ceramic construction around a titanium inner case.

Water resistance is 500 meters, sealed by a screw-down crown at three o'clock and a helium escape valve on the opposite flank of the brushed midcase. The unidirectional bezel is titanium with a knurled edge and a blue ceramic insert, and the domed sapphire crystal carries an anti-reflective treatment.

The titanium caseback is finished in blue PVD and carries a map of the world's oceans. Bremont describes the colorway as inspired by the point where ocean and ice meet, giving the watch a colder, darker look than its siblings while keeping the tool-watch character the brand is known for.

The dial is black with a pronounced three-dimensional wave pattern and applied trapezoidal and circular indices outlined in black. The trapezoids extend inward from the bezel toward naval-inspired crosshairs at the center, and the minutes track is printed white on the inclined black inner flange.

London is at six o'clock in orange, alongside orange highlights at the 15, 45 and 60 markings. The date window at three o'clock uses a matching black date wheel, and the hour and minute hands are finished in polished black gold, with an arrow-tipped central seconds hand treated the same way.

All markers and hands are filled with blue-emitting Super-LumiNova. The movement is Bremont's calibre BB64AH, a Sellita SW300-based automatic running at 28,800 vibrations per hour with 56 hours of autonomy, built around a Glucydur balance wheel, an Anachron balance spring and a Nivaflex mainspring.

Three reference variations differ only by strap. A black-and-blue woven NATO-style fabric, a blue embossed rubber strap with a leather lining, or a black rubber chevron strap are all offered, with the two rubber options quick-release. The price stays €7,750 regardless of strap choice.

Field-tested in Iceland

Bremont ambassador Aldo Kane, a former Royal Marine, took the Deep Blue to Iceland for field testing. He wore it while entering the freezing waters of glacial lakes and onto glaciers themselves, in mountain terrain and unpredictable weather, sticking with the blue rubber-and-leather strap rather than the black rubber option.

The choice is a continuation of the series' proving ground. When the Full Ceramic line debuted, Kane took the Jungle Green and Tactical Black versions on scientific missions in jungle environments, so the ceramic case has now been exercised from the tropics to the Arctic before reaching a single customer.

The pricing carries across currencies at €7,750, US$7,400 and £6,450. That positions the watch against established ceramic divers: the 41mm Tudor Black Bay Ceramic costs €7,110 on a bracelet and €5,630 on a leather-and-rubber strap, and a black ceramic Longines HydroConquest in the same 43mm size retails at €4,600.

Bremont is the British watch brand with roots in aviation and tool watches, built around durability and legibility rather than dress. The Supermarine dive line is its water-focused pillar, and the Full Ceramic's move to ceramic and titanium in 2024 marked a new generation of high-performance divers for the maison.

That material shift is meaningful for a dive watch: ceramic is light and highly scratch-resistant, two qualities a tool watch benefits from underwater, though it is also notoriously demanding to machine and finish with little room for error once shaping begins.

The Deep Blue fits squarely within our coverage of garage and its attention to instruments built for hard use.

Bremont is also a brand we follow for where its value proposition lands. The Deep Blue's ceramic construction and limited run are the story here, but its price against Tudor and Longines alternatives keeps the comparison honest, and the brand's tool roots carry through in every detail of the case.

The watch can be ordered in all three strap versions at the same price, and Bremont directs buyers to bremont.com. The Deep Blue's 250 pieces are the ceiling, and the brand gives no word yet on whether this colorway stays limited once the run sells through.

What the Deep Blue establishes is a fourth permanent color in a collection that was a complete revamp only two years ago. For buyers weighing a ceramic diver, the question is whether the blue-on-black combination, the limited status and the 500-meter rating justify the premium over the cheaper Longines beneath it.

Bremont has not said when the Deep Blue ships, but the strap system, the helium valve and the Iceland field work confirm the watch arrives as a finished tool rather than a concept. The 250 pieces will likely find buyers among collectors already committed to the Supermarine's ceramic generation.
