The next-generation dive watch, the Engineer Master II Diver Chronometer complies with the many requirements imposed by deep-sea diving. This robust and aesthetically functional timepiece delivers remarkable performance with an inner bezel, illuminated by micro gas tubes and a 2-crowns design. This chronometer has a water resistance of 300 meters and runs the BALL RR1101-C caliber, certified by the COSC. To ensure high accuracy in adverse conditions, a mu-metal shield surrounds the caliber allowing an anti-magnetic protection to an intensity of 1, 000 Gauss. BALLs patented Amortiser® system absorbs energy created by external shocks. The Diver Chronometer features a bi-directional sapphire internal bezel used to count down dive time and ensure safety. Activated by the crown at 2 oclock, the internal diving bezel can be operated while completely submerged under water to time the safety stop. This bezel remains visible even in total darkness thanks to the cutting-edge Swiss technology o
