Bremont’s Supermarine has gone blue all the way through. The Deep Blue fires the line’s full ceramic case in deep blue for the first time, around a titanium inner case, and it is rated to 500 meters. Bremont is building 250 pieces, with orders open on all three strap versions.

Ceramic divers are usually steel watches wearing ceramic jewelry, a bezel insert here, a case treatment there. This one is a single monobloc block of blue ceramic over the titanium inner case, which removes the mixed-material seams and leaves the 43mm watch head at 74 grams.

How does ceramic hold up underwater?

Ceramic shrugs off scratches that would scar steel and cannot corrode in salt water, while the titanium core takes the pressure and a helium escape valve is built in.

The bezel is knurled titanium with a ceramic insert in matching blue, the crown carries the Wayfinder compass rose, and the titanium case back is engraved with a map of the world’s oceans. The case is 51.1mm lug-to-lug and 12.9mm thick, which is slim work for this depth rating.

What’s driving it?

The black dial has a 3D wave texture, with trapezoid indexes that form a naval crosshair, blue Super-LumiNova and a date at 3 o’clock.

Inside is Bremont’s BB64AH automatic with a 56-hour power reserve, so a watch taken off Friday night is still running Monday morning.

Has it been through real cold water?

Bremont gave the watch to Aldo Kane, the former Royal Marine sniper who fronts its Tested Beyond Endurance platform, and sent him to Iceland. The published test point sits at 64.1466° N, 21.9426° W, in glacial lake and fissure country with water around 2°C and visibility past 100 meters.

Is the Deep Blue the one to buy?

Buy it if you want the ceramic Supermarine in blue, since the run is short, or if you dive cold water and want a case that cannot corrode or lose its finish to a rock or a boat ladder. The blue embossed rubber with leather lining suits dinner, and the NATO and plain rubber suit the boat.

Skip it if you need a bracelet, because there isn’t one, or if a case this size wears big on your wrist.

Bremont sells it only direct. For a high-tech ceramic automatic diver on Amazon, the closest match is Rado’s Captain Cook in blue ceramic on a blue rubber strap.
