Bell & Ross maybe best known for their square case aviation- and military-themed watches but every now and then, the French brand does pull off a few surprises. This year at Baselworld Bell & Ross unveiled the BR 03-92, a professional diving watch water that uses the brand’s characteristic square case and a unidirectional rotating bezel.

The square shape works well on this diver.

This isn’t the first time Bell & Ross has dabbled in the production of diving watches. In 1997, it launched the Hydromax, a professional diving down to 11,1000 meters, thanks to a major technical innovation: a case entirely filled with a patented transparent fluorinated oil. Ten years later, the brand launched tonneau-shaped BR 02 line complete with its helium decompression valve and its ultra-resilient domed sapphire crystal.

The new diver uses a 42 mm satin-polished steel case that has a reinforced caseback to guarantee extreme water resistance. It also has a soft-iron cage on the inside to protect the movement from magnetic fields. Further, the sapphire crystal with anti-reflective coating is an impressive 2.85 mm thick, compared to the 1.50 mm on the classic steel BR 03-92.

Bell & Ross’s ‘circle in a square’ aesthetic is underlined by the presence of a unidirectional bezel with 60 stops and a black anodized aluminum insert with a luminescent dot at 12 o’clock. Like most diver’s watches, this one has a crown guard and a crown fitted with a rubber insert for improved ergonomics.

The deep black dial features indices in skeletonized metal applique filled with white Superluminova, a stark contrast that provides for good legibility. The hour hand is orange and the minute hand, used to calculate dive time contains white Superluminova. Finally, the second hand is also filled with white Superluminova for optimum legibility under water.

The bezel has a black anodized aluminum insert.

The watch is powered by self-winding Calibre BR-CAL.302 which is Bell & Ross’s version of the Selita’s SW300. This is a 4 Hz (28,800 vph) movement with a power reserve of 38 hours. The watch is available with two straps: the first is made from woven black rubber with a steel pin buckle. The second is in black synthetic fabric, allowing the watch to be quickly adjusted over diving suits thanks to a Velcro closure system. The watch is priced at $3,722 (approx. Dh13, 670).
