The Supermarine Full Ceramic unveils a new era of toughness for Bremont’s flagship diver

Buffy Acacia

As a brand that prides itself on its ties with aviation, Bremont’s Supermarine line of dive watches has historically felt more like an obligation than a release of passion. That has changed significantly under Davide Cerrato’s leadership, as 2024 saw a complete overhaul of the Supermarine’s design, specifications, and personality. Doubling down on the high-tech, militaristic angle, the new Bremont Supermarine Full Ceramic has been field tested for extreme durability.

The case

As a watchmaking material, ceramic has all but entered the mainstream. There is plenty of innovation left in regards to creating alloys and stabilising unusual colours, but there are no doubts about its supreme scratch resistance. While the Supermarine Full Ceramic Tactical Black is fantastic in its brooding versatility, the Jungle Green version really lets the various textures of the ceramic case shine. The majority is sandblasted for a soft effect that’s velvety to the touch, but retains a no-nonsense matte lustre. The utilitarian ruggedness is enhanced with small sections of brushing on the bezel, which still catch enough light to contrast highly at certain angles. The bezel itself is made of titanium with a colour-matched PVD coating, and a ceramic insert.

The shape of the case lends itself to adventure, with substantial crown guards that extend away from the case, ensuring that unscrewing and setting the crown isn’t inhibited at all. However, don’t forget that the Supermarine Full Ceramic is still primarily a dive watch. It far exceeds the minimum requirements, reaching a water resistance of 500 metres, with a hidden helium escape valve on the left side of the case. At 43mm in diameter, it holds a commanding wrist presence, but it’s not overly thick thanks to a 13mm height. As far as bulky exploration watches go, it’s dimensions are tame.

The dial

Legibility is going to be a priority for pretty much any sports watch, but especially tactical dive watches. A dark dial with luminous white paint is pretty much as good as it gets, but Bremont’s attention to detail adds a few extra dimensions. The blacked out handset almost makes the luminous portions seem like they’re floating across the dial, while the markers at 12, 6, and 9 are easily distinctive shapes to aid orientation in the dark.

Neither dial, black or green, is entirely monotone. It’s subtle, but there is a slight gradient from the centre of the dial to the smoky edges which injects some life into them. A tiny splash of contrasting colour is provided by the Supermarine dial text and numerals on the chapter ring. The Bremont logo is as bold as the rest of the watch, and the date window at 3 o’clock is neatly integrated to be useful and not distracting.

The movement

Behind a solid caseback that’s engraved with a map of Earth’s oceans, the Bremont Supermarine Full Ceramic is powered by the calibre BE-92AV, which is a Sellita SW300-1. Itself a Swiss clone of the ETA 2892-A2, the SW300 is a great choice for a luxury watch you don’t want to think about too much. It’s reliable, has a well-regarded accuracy tolerance, and slim. The power reserve has been upped to approximately 50 hours thanks to the optimised mainspring barrel, as the balance ticks at a smooth 4Hz beat rate. It has automatic winding, but is only 3.6mm thick, which contributes to the Supermarine’s modest thickness despite its 500-metre water resistance.

The strap

Both the varieties of the Supermarine Full Ceramic are available on either a fabric NATO strap with hook-and-loop closure or a rubber strap. They’re both waterproof and comfortable options, however you may have a preference for the feel of fabric or rubber. The rubber strap has straight ends and raised arrow shapes for a more geometric and traditional look, while the NATOs, colour matched to each model, pass through both lugs for an integrated effect. There is no price difference between the two, so it really comes down to personal preference. The lug width is 22mm, so you will also have plenty of aftermarket options.

The verdict

The Bremont Supermarine Full Ceramic is certainly a departure from the original Supermarine, and a welcome change for its revised architecture – and it’s great to see the ceramic watch landscape expand beyond the handful of brands who flourish in that area. Compared to the regular Supermarine 300M however, the near doubling in price feels hard to swallow for the ceramic upgrade and 500m water resistance with the same movement. It does fill the specific niche of a high-end, high-adrenaline ceramic diver though, so it could find its audience and fans that are willing to splash the cash.
