BALL Engineer Master II Diver Chronometer | 42mm Automatic Blue Dial

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. BALL’s 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 o’clock, 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 of self-powered micro gas lights. Gas tubes are placed underneath the bezel as well as on the dial and the hands for an absolute luminosity. With a thickness of only 13.5mm, the 42mm Engineer Master II Diver Chronometer is available with a black or a blue dial, and either on a stainless steel bracelet or rubber strap. It features hours, minutes, sweep seconds and a magnified date.
