Bremont Supermarine Full Ceramic Deep Blue Takes The Dive Watch To Iceland

Built for the depths and tested in some of Iceland’s harshest conditions, Bremont’s latest Supermarine Full Ceramic brings together ceramic construction, 500-metre water resistance and a distinctly deep-blue aesthetic.

The Bremont Supermarine Full Ceramic Deep Blue is the latest chapter in Bremont’s Full Ceramic dive-watch collection, introducing a new colourway inspired by the meeting point between ocean and ice. Limited to 250 pieces, the 43 mm model combines a ceramic monobloc case with a titanium inner case, a helium escape valve and 500 metres of water resistance, continuing the Supermarine line’s focus on high-performance construction and advanced materials.

The Full Ceramic family first appeared in 2024 as part of a new generation of Supermarine watches designed around resistance, durability and the use of modern materials. Ceramic plays a central role in that concept. It offers high scratch resistance while remaining relatively lightweight, although its manufacturing process is considerably more demanding than conventional case materials. For Bremont, that combination fits naturally within the brand’s tool-watch philosophy.

With Deep Blue, the material is paired with a colour palette intended to evoke the transition between deep water and frozen landscapes. The ceramic case is matched with a ceramic bezel insert inside a knurled titanium unidirectional bezel, while the black dial introduces a more technical contrast. The result is a watch that remains recognisably part of the Supermarine family while giving the Full Ceramic concept a colder and more exploratory character.

A Ceramic Dive Watch Built For 500 Metres

The case measures 43 mm in diameter, with a 50 mm length and a 13 mm depth. Beneath the ceramic exterior sits a titanium inner case, while the screw-down crown and helium escape valve reinforce the watch’s diving credentials. Water resistance is rated at 50 ATM, equivalent to 500 metres.

The bezel follows the same functional approach. A blue ceramic insert is integrated into a knurled titanium unidirectional bezel, providing the necessary timing function for diving while adding another layer of material contrast. The closed caseback is made from PVD blue titanium and carries an engraved world map of the oceans, giving the reverse of the watch a direct connection to its maritime purpose.

A domed sapphire crystal with anti-reflective treatment protects the dial. At 74 grams for the watch head alone, the Deep Blue also keeps the overall construction relatively light considering its dimensions and 500-metre rating.

A Black Wave-Effect Dial

The dial takes a darker approach than the name might initially suggest. Rather than using a blue surface throughout, Bremont has chosen a black dial with a three-dimensional wave-effect pattern. The texture adds depth while reinforcing the connection to the underwater environment.

The applied trapezoid indexes are particularly distinctive. Their shapes flow from the bezel onto the dial and converge visually towards the centre, creating a naval-inspired crosshair. The minute track sits on a black outer dial ring, maintaining the instrument-like character expected from a Supermarine.

The hour, minute and seconds hands are black-gold plated and filled with the latest-generation Super-LumiNova, emitting a blue glow in low-light conditions. The same blue-emission treatment is used on the applied indexes. At 3 o’clock, the date display is integrated into the composition with a date wheel matched to the black dial rather than introducing a contrasting white disc.

Tested Beyond The Ocean

Bremont did not limit the testing of Deep Blue to conventional diving environments. The watch was taken to Iceland, where freezing glacial lakes, exposed glaciers, high mountains and rapidly changing weather provided a very different test environment.

Bremont ambassador Aldo Kane, a former Royal Marine and veteran of numerous expeditions, was involved in testing the Supermarine Full Ceramic line. Earlier versions in Jungle Green and Tactical Black had already been used in demanding environments, while Deep Blue was subjected to Iceland’s combination of extreme cold and exposed terrain.

The choice of Iceland is particularly appropriate for the Deep Blue concept. The watch was designed around the meeting point of ocean and ice, and its testing placed the construction in an environment where cold-water diving and harsh mountain conditions could be experienced within the same expedition.

Bremont BB64AH

Inside the Bremont Supermarine Full Ceramic Deep Blue is the BB64AH automatic movement. The calibre operates at 28,800 beats per hour, or 4 Hz, and provides a 56-hour power reserve.

The movement uses a Glucydur balance wheel, Anachron balance spring and Nivaflex mainspring, with 25 jewels. Its functions remain deliberately straightforward for a tool-oriented dive watch: central hours, minutes and seconds, together with a date indication at 3 o’clock.

That combination of a relatively simple functional display and a robust movement is consistent with the Supermarine’s purpose. The emphasis is not on adding complications, but on creating a dependable mechanical instrument capable of operating in demanding conditions.

Three Strap Options

Bremont offers the Deep Blue with three strap configurations. The first is a black rubber strap with a quick-release system, while the second combines black and blue woven fabric in a NATO configuration. The third option is a blue embossed rubber strap with a leather lining.

These choices give the same case different personalities, from the more technical character of the rubber configuration to the more expedition-oriented appearance of the NATO strap. All three remain consistent with the watch’s tool-watch positioning.

A New Chapter For The Supermarine Full Ceramic

The Bremont Supermarine Full Ceramic Deep Blue brings together several of the defining characteristics of the current Supermarine collection: ceramic construction, a 500-metre diving rating, titanium reinforcement and a highly legible instrument-style dial. What distinguishes this edition is the way those technical elements are connected to the visual idea of ocean meeting ice.

Limited to 250 pieces, the Deep Blue also continues Bremont’s strategy of using the Supermarine platform to explore different materials, colours and environments without moving away from its functional foundation. Tested in Iceland and built for 500 metres, it is a dive watch that takes its name seriously, while adding a distinctly exploratory edge to the Full Ceramic line.
