Bremont Takes the Supermarine Full Ceramic Into Deep Blue

Bremont’s modern Supermarine line gets its most oceanic Full Ceramic execution yet with the new Deep Blue.

The limited edition doesn’t change the formula that arrived with the refreshed dive range in 2024, but it gives the 500-metre diver a sharper visual identity through blue ceramic, black dial work and titanium hardware.

It’s a technical-looking watch in the brand’s familiar tool-watch lane, rather than a decorative colour exercise.

At a glance

Blue ceramic gives the Supermarine a colder edge

The Deep Blue follows earlier Supermarine Full Ceramic models in Polar White, Jungle Green and Tactical Black, but its colour treatment feels closer to the watch’s purpose.

The case measures 43mm across, 13mm thick and 50mm lug-to-lug, which places it firmly in contemporary instrument-watch territory.

That said, the use of ceramic and titanium keeps the weight down to 74 grams, a useful detail for a watch built around a substantial dive-ready case profile.

The blue ceramic case is paired with a brushed titanium midcase, a screw-down crown at 3 o’clock and a helium escape valve on the opposite side.

Up front, the unidirectional titanium bezel carries a blue ceramic insert, while the domed sapphire crystal receives anti-reflective treatment.

The titanium caseback is finished in blue PVD and engraved with a map of the world’s oceans, a detail that connects the watch to the wider Supermarine theme without turning the design theatrical.

A black wave dial with instrument-watch geometry

The dial is where the Deep Blue leans hardest into its naval character.

Bremont uses a black dial with a pronounced three-dimensional wave pattern, then overlays applied trapezoidal and circular markers outlined in black.

The trapezoidal markers extend visually from the bezel toward the centre of the dial, forming a crosshair-like layout that gives the watch a more technical read at a glance.

The inclined inner flange carries a white printed minute track, with 15, 45 and 60 markings joined by an orange London signature at 6 o’clock.

A date window sits at 3 o’clock with a matching black date wheel, helping it sit more quietly within the dial.

The hour, minute and central seconds hands are polished black gold-plated, with the seconds hand shaped by an arrow tip.

Blue-emission Super-LumiNova is applied to the hands and markers, keeping the low-light display consistent with the blue-and-black scheme.

The familiar BB64AH automatic inside

The Deep Blue uses Bremont’s calibre BB64AH, the same automatic movement architecture found in other Supermarine Full Ceramic references.

It’s a Sellita-based SW300 movement with 25 jewels, a 28,800vph frequency and a 56-hour power reserve.

The movement specification includes a Glucydur balance wheel, Anachron balance spring and Nivaflex mainspring.

Functionally, it keeps things straightforward with central hours, minutes and seconds plus a date display, which suits the directness of the watch.

Details & Specifications

The Supermarine Full Ceramic Deep Blue is less about expanding the collection’s capabilities than sharpening its character.

For collectors drawn to Bremont’s dive watches but looking for something more distinctive than black ceramic, this 250-piece edition adds colour without softening the model’s tool-watch intent.
