Bremont’s Ceramic Diver

Bremont expands its Supermarine Full Ceramic collection with the Deep Blue, a 250-piece limited edition combining a blue ceramic exterior, serious professional diving specifications and a distinctive ocean-inspired design. At £6,450, the new model enters a competitive segment where material innovation and technical capability are increasingly important to luxury sports-watch positioning.

◉ The 43mm Deep Blue is limited to 250 pieces worldwide and carries a retail price of £6,450.

◉ Its blue ceramic case, titanium inner construction and 500-metre water resistance position it as a technically focused dive watch.

◉ An automatic BB64AH movement delivers a 56-hour power reserve, while three strap configurations offer different wearing styles.

A New Deep Blue Edition

The Supermarine Full Ceramic Deep Blue is the latest colourway in Bremont’s ceramic dive-watch series. Its design takes inspiration from the meeting point of ocean and ice, translating that theme into a matte blue ceramic case and a black wave-effect dial.

The 43mm case is built around a monobloc ceramic exterior, with a titanium inner case designed to provide additional structural support. Ceramic is valued in watchmaking for its low weight and high scratch resistance, although manufacturing it requires precise control during shaping and high-temperature sintering.

Bremont says its ceramic components shrink by approximately 23% during the sintering process at 1,450°C. The finished surface is sandblasted for a matte appearance. Bremont Watch Company+1

Built for Serious Diving

The Deep Blue is specified for 500 metres of water resistance and includes a helium escape valve, screw-down crown and unidirectional rotating bezel. Its titanium bezel construction is paired with a blue ceramic insert.

The black dial features a three-dimensional wave pattern, trapezoidal hour markers and a central crosshair motif. The hands and indexes use blue-emission Super-LumiNova, designed to maintain visibility in low-light underwater conditions.

Power comes from Bremont’s automatic BB64AH calibre, operating at 4Hz with 25 jewels and a 56-hour power reserve. The movement is housed within the titanium inner structure, while the caseback is engraved with an ocean map based on the Spilhaus projection. Bremont Watch Company+2

Limited Production, Three Strap Options

Bremont is producing 250 examples of the Deep Blue. Buyers can choose between a blue embossed rubber strap with leather lining, a black rubber strap or a black-and-blue NATO-style fabric strap. All three configurations are listed at £6,450.

The edition follows earlier ceramic Supermarine releases, including Tactical Black and Jungle Green. The new colourway gives the collection a colder visual identity while retaining its central technical proposition: a lightweight ceramic dive watch with substantial water resistance and a mechanical movement.

The Ceramic Dive-Watch Competition

Ceramic has become an increasingly visible material in luxury sports watches, particularly in models where scratch resistance, weight and distinctive colour are important selling points. Yet it is not without trade-offs: ceramic can be brittle under sharp impact, making the use of titanium in key structural components a notable engineering choice.

At £6,450, Bremont is competing in a segment that includes established Swiss and international dive-watch names. The Deep Blue’s differentiation rests on its full-ceramic case architecture, 500-metre rating, limited production and distinctly British brand identity.

For collectors, the central question is whether the combination of technical specification, material execution and exclusivity justifies its position in an increasingly crowded luxury dive-watch market.
