Professional divers need watches that remain readable and reliable in harsh conditions. BR 02-92 Carbon is one such timepiece that features various useful complications. The watch is equipped with Swiss-made ETA 2892 calibre that performs 28 800 vibrations per hour and has 26 bearing jewels. A power reserve of over 40 hours is available for the convenience of the wearer. Hands, numerals, indices and bezel elements are covered with luminous paint for improved night time readability. The uni-directional elapsed time bezel is one of the most prominent watch characteristics. Other useful features include a decompression valve, a date window positioned between 4 and 5 o'clock, screw-in crowns and scratch-resistant sapphire crystal glass with anti-reflective coating.
