Introducing a genuine diver's watch with a bronze alloy case

 Bell & Ross has announced the BR-03 Diver Black Bronze, a watch designed to return to the origins of professional diver's watches. As the name suggests, the case is crafted from bronze, which gives it a warm glow, while the black dial creates a sleek design. In addition to the iconic wide rubber strap, this model also comes with a hook-and-loop strap suitable for serious diving.

 The newly announced BR-03 Diver Black Bronze is a professional diver's watch that strictly complies with the international standard ISO 6425. This model's key features, which are based on or exceed this standard, include water resistance to 300m, a unidirectional rotating bezel to prevent measurement errors, and legibility from 25cm in complete darkness. Other features, including a screw-down crown that's easy to operate even while wearing diving gloves and an anti-reflective sapphire crystal, further enhance its practicality.

Automatic winding (Cal.BR-CAL.302-1). 28,800 vibrations per hour. Power reserve approximately 54 hours. Bronze case (42mm x 42mm, 12.3mm thick). 300m water resistant. 792,000 yen (tax included)

 Bronze, an alloy of copper and tin, is a material that has been in use since around 2000 BC. It has been used in ships since ancient times due to its ease of workability, sufficient strength and toughness, and high corrosion resistance in seawater. In modern times, it has also been an essential material for ship propellers and diving equipment.

 In keeping with this maritime history, the case and bezel of the BR-03 Diver Black Bronze are crafted from a CuSn8 alloy, consisting of 92% copper and 8% tin. Not only does this alloy possess excellent properties, but it also exhibits a warm copper-gold color, a key element of the watch's design.

 Another feature of bronze alloys is that they change appearance over time. This model will also change color depending on the sea breeze, humidity, and daily wearing environment, making it a model that can be enjoyed as it grows into a special piece that will record time and stories with its owner.

By combining it with a hook-and-loop strap, it can be worn over a diving suit, making it a coordinated look that matches not only diving but also outdoor use.

 Bell & Ross is known for its designs inspired by aircraft cockpit instruments, with a "circle in a square" silhouette reminiscent of an instrument, a large, eye-catching dial, and highly visible dials as its design codes. This model also carries on this design code, combining a square case measuring 42mm in height and width with a black dial.

 The dial features a bar and dot index, typical of a diver's watch, and the arrow-shaped hour hand enhances legibility. The indexes, hour and minute hands, and the tip of the second hand are filled with Super-LumiNova to ensure visibility in the dark. The bezel insert is made of black ceramic and has a glossy finish.

 This watch comes with a wide rubber strap that accentuates the massive design of the BR-04 series. The tapered design creates a silhouette that is characteristic of Bell & Ross. It also comes with a hook-and-loop strap that allows for flexible length adjustment. This allows you to wear the watch even when wearing a diving suit, allowing you to take it out into the world where its high waterproofness and visibility can be fully utilized.
