Each Bell & Ross chronograph is designed by men with a passion for perfection in the manufacture of fine quality watches and chronographs able to withstand the rigors of extreme careers. Bell & Ross watches are intended for astronauts, pilots, divers, bomb-squad experts, explorers and others who require that their timepiece stand up to high altitudes, arctic temperatures and high acceleration. Airplane instrument panel design principles have been employed in the design of the face, Swiss chronograph movements are at the cutting edge of mechanical precision and every Bell & Ross chronograph is optimally water-resistant. Each Bell & Ross requires the painstaking assembly of up to 350 individual parts to produce such accurate and mechanically perfect instruments.

The Vintage Collection evokes the origins of the mechanical watch for professionals and is inspired by military watches. The Classic Collection was directly inspired by pilots' watches and features water resistance to 200 meters (650 feet). The Diver 300 model is actually water-resistant to a depth of 300 meters (975 feet) and features an innovative TE or water-resistance indicator which turns blue when the watch's water resistance should be checked.

The High Tech collection was designed to address the particular needs of men who put their lives on the line every day they go to work. Designed initially for space flight, the Space 1 was worn by German astronaut Reinhart Frrer on the Spacelab mission. The Pilot line features simplicity and is designed to be accurately read in a fraction of a second. The GMT line features multiple time zones. The Military M1 and M2 models were designed specifically for military and helicopter pilots, respectively. The two most narrowly targeted models of the High Tech collection are the Type Deminer for bomb-squad experts and the Hydro-Challenger for deep-sea exploration (hyperbaric pressure resistant to 1,100 Atm, the equivalent of a depth of 11,100 meters.
