Man has always been drawn to the captivating beauty of the depths and the sense of freedom of the underwater world.

When entering the salty water and feeling the pressure build as depths are approached, where survival depends on the legibility of the information... Bell & Ross diving watches offer the perfect solutions when exploring an environment that is as fascinating, as dangerous.

The maritime expertise of the brand is born from the convergence of the knowledge and skills of designers, master watchmakers and underwater experts. The new BR 03-92 Diver watch is writing a brand new chapter in the story of the brand’s relationship with the oceanic world.


Bell & Ross and diving

A prolific story… 



In 1997, Bell & Ross became the leader in professional diving watches with the launch of the HYDROMAX®, an iconic model which still holds one of the most impressive records in the history of diving watch production. Designed to response to the most extreme conditions encountered in professional diving, the HYDROMAX® can withstand a pressure of 1 110 bar, equivalent to a depth of 11,100 meters, thanks to a major technical innovation: a case entirely filled with a patented transparent fluorinated oil.



In 2007, Bell & Ross launched a new collection specifically designed for an underwater environment, the BR 02, which is instantly recognizable, thanks to its tonneau-shaped case; its helium decompression valve and its ultra-resilient domed sapphire crystal.



This year, with a wealth of experience in the aeronautical and military domains, master watchmakers, designers and seasoned divers joined forces to create a new professional diving instrument. Building on the strong links forged with the maritime world, Bell & Ross unveiled an all- new diving watch featuring the brand’s iconic square case: the BR 03-92 Diver, the first square diving watch created by the brand that offers water resistance to 300 meters. There are men and women whose professions expose them to extreme temperatures, violent acceleration or dangerous pressure. The BR 03-92 was designed for them.


Technical specifications to swiss standards


Only watches that meet the requirements defined by international standard ISO 6425 can be labeled as «diving» watches. The twelve-pages from the International Organization for Standardization (ISO) on diving watches contain an exhaustive list of the essential qualities of a «wristwatch designed to withstand diving in water at depths of at least 100 meters and possessing a system to control the time.» The general requirements for a professional diving watch recognized as such by standard ISP 6425 are, among others, a minimum water resistance of 100 meters and the presence of a time preselection device (a 60-minute calibrated uni-directional rotating bezel), which is protected against accidental rotation or incorrect setting.

During a dive, the legibility of the watch’s indications is critical, and may even be lifesaving. As a result, the indices must be easily legible at a distance of 25 cm in the dark. Likewise, the hour hand indication must be distinct from the minute hand, with the minutes more legible to allow for better time calculation. The watch must pass a series of demanding tests on its attachments and its resistance to impacts, thermal shocks in salt water and high pressure, among others.

A professional square diving watch


The BR 03-92 Diver is a professional diving instrument, water resistant to 300 meters and driven by a Swiss self-winding mechanical movement with proven robustness and accuracy.

With ergonomics perfectly designed for underwater use, the iconic Bell & Ross square case is equipped with a 60-minute calibrated uni-directional rotating bezel, whose luminescent dot at 12 o’clock is used to set time references, both on the surface and at depth. The bezel, designed for professional use, allows immediate calculation of the time spent underwater. It is uni- directional (meaning it can only be rotated in one direction –in this case, anti-clockwise) to prevent the references from being lost. If it is moved accidentally, it automatically shortens the dive time to avoid any risk.

Screwed down to withstand the pressure at great depths, the crown of the BR 03-92 Diver is equipped with a guard that guarantees complete protection against impacts and optimal water resistance. The carefully designed crown is also fitted with a rubber insert for improved ergonomics.

With its sophisticated design and uncompromised functionality, the new Bell & Ross diving watch is protected by a steel exterior to withstand the rigors of underwater exploration. The case is reinforced with a very thick back (2.80 mm on the BR 03-92 Diver, compared to 1.80 mm on the BR 03-92 Steel), once again guaranteeing extreme water resistance. Invisible from the outside, yet crucial for its reliability, the case of the BR03-92 Diver is also equipped with a soft iron cage to increase its resistance to magnetic fields.

A further guarantee of flawless water resistance, the sapphire crystal with antireflective coating is an impressive 2.85 mm thick, compared to the 1.50 mm on the classic steel BR 03-92. The deep black dial features indices in skeletonized metal applique filled with white Superluminova® for enhanced legibility, thanks to the maximum contrast between the black of the dial and the white of the time indications. The hour hand is orange and the minute hand contains white Superluminova®, allowing them to be distinguished at a glance; the minute hand is also used to calculate the dive time. Finally, the second hand is also filled with white Superluminova® so that the watch’s correct operation is clearly visible, even underwater.

The BR 03-92 Diver comes in a water-resistant PELICAN® box, and is available with two straps: the first is made from woven black rubber with a steel pin buckle. The second is in ultra- resilient black synthetic fabric, allowing the watch to be quickly and ergonomically adjusted over the suit thanks to a Velcro closure system. Both have been designed for professional underwater use. Their style instantly evokes the ocean depths.

A reliable instrument for professional divers


Each Bell & Ross watch is designed in harmony with the context in which it operates. In the diving world, Bell & Ross has developed measuring tools that are perfectly adapted to the sub-aquatic environment, and are the efficient companions of divers under any circumstance.

Legible, practical, accurate, reliable and unique in their distinctive square shape, Bell & Ross watches meet the exacting requirements of professionals and also reflect the personality of those opting for an everyday use.
