Engineer Master II Diver GMT is the result of the cooperation between Ball and freediver Guillaume Nery. This beautiful watch is designed to correspond to the needs of professional divers. It is equipped with Swiss-made ETA 2893-2 automatic calibre that performs 28 800 vibrations per hour and has 25 bearing jewels. A 42-hour power reserve is available for the convenience of the wearer. The watch is protected from shock, magnetic influences and water penetration. Hands, indices, numerals and the bezel are illuminated through the use of 53 self-powered micro gas tubes that glow 100 times brighter than luminous paint. A silver ring and a separate hand indicate the GMT display. Additional features include a date display between 4 and 5 o’clock, diamond-like carbon (DLC) stainless steel construction, rotating inner bezel, screwed-in crowns and scratch resistant sapphire crystal glass with anti-reflective coating.
