Black And Bronze: The Latest Evolution Of The Bell & Ross BR-03 Diver
Bell & Ross expands its modern BR-03 Diver lineup with the new BR-03 Diver Black Bronze, a model that combines professional dive watch specifications with the warm character of a bronze case. Built according to ISO 6425 standards, this 42mm diver blends the brand’s recognizable square case architecture with robust underwater capability.

42mm Bronze Case with Functional Construction
The BR-03 Diver Black Bronze features a 42 mm case crafted from CuSn8 bronze, an alloy known for its durability and resistance to corrosion. The specific composition includes a small percentage of phosphorus, enhancing the metal’s stability and helping preserve its tone over time.

The case is finished with a mix of satin-brushed surfaces and polished bevels, highlighting the geometry of the signature rounded-square design secured by four exposed screws. Despite its distinctive shape, the watch meets strict professional dive standards, offering 300 meters of water resistance.
A solid stainless steel caseback ensures structural integrity under pressure. The engraved diving helmet motif pays tribute to traditional underwater equipment while reinforcing the model’s tool-watch identity.
Black Dial and Ceramic Bezel for Maximum Legibility
Contrasting the bronze case is a glossy black lacquered dial, designed for clarity and durability. The applied hour markers and hands are framed in a gilded tone that complements the case material. All luminous elements are filled with white Super-LumiNova, emitting a green glow in low-light conditions.

A discreet date window positioned at 4:30 maintains dial symmetry while preserving legibility with white numerals on a black disc.
The unidirectional rotating bezel features a black ceramic insert, chosen for its scratch resistance and long-term color stability. Ceramic also adds a technical contrast to the bronze, preventing excessive use of metal while ensuring durability in demanding environments.
Automatic Movement: Caliber BR-CAL.302-1
Powering the watch is the Caliber BR-CAL.302-1, based on the Sellita SW300-1 architecture and customized for Bell & Ross. The movement operates at 28,800 vibrations per hour (4Hz) and delivers an extended 54-hour power reserve.
This automatic caliber is known for reliability and precision, aligning with the BR-03 Diver’s positioning as a professional-grade instrument.
Strap Options for Versatility
The BR-03 Diver Black Bronze is delivered with two strap options, a textured black rubber strap with a matching bronze pin buckle, optimized for aquatic use, and a black canvas strap with dual Velcro fastening, offering a more tactical aesthetic
Both straps are designed to complement the watch’s sport-focused functionality while allowing for adaptability in different environments.
