As part of its on-going quest for excellence, Bell & Ross has reworked the high-tech ceramic and developed a special manufacturing process in its workshops. It enhances the intrinsic qualities of this material, which is virtually scratch-proof, pleasant to wear, soft to the touch and thermo-regulated, instantly reaching body temperature when worn. Almost as tough as a diamond, the high-tech ceramic developed by Bell & Ross is incredibly hardwearing, non-deformable, lighter than steel and hypoallergenic. Reminiscent of the antireflective finish used on aircraft instrument panels, the matte black ceramic is perfectly in tune with the aeronautical codes so fundamentalto Bell & Ross. The sober design, black dial, large white numerals, shape of the hands and photoluminescent coating allow immediate reading of the time, in broad daylight as well in darkness. Not every watch can be a diver watch. Official regulations set out very specific criteria defining a true diving watch. The ISO 6425 standard lists a great number of obligatory technical parameters. Those include water-resistance to a minimum depth of 100 meters, the presence of a unidirectional rotating bezel with a graduated minutes scale, an operation indicator and luminescent markers, legibility in the dark, anti-shock and anti-magnetic protection.
