BALL Watch Engineer Master II Diver Chronometer Limited Edition

Introduced in 2021, BALL Engineer Master II Diver Chronometer is a COSC- certified automatic diving watch. It is a limited edition of 1,000 pieces.

In 2006, BALL Watch Company introduced its first-generation dive watch: a robust, aesthetically functional timepiece that delivered remarkable performance with an inner bezel, illuminated by micro gas tubes and a 2-crowns design. Over the last 15 years, its “Engineer Master II” collection has boasted a wide range of timepieces that have complied with the many requirements imposed by deep-sea diving.

Water resistant to 300m/1,000ft and equipped with the BALL RR1101-C caliber, each Engineer Master II Diver Chronometer watch has been certified by the Swiss Official Chronometer Testing Institute (COSC). To ensure high accuracy in adverse conditions, the movement is safeguarded by powerful resistance technologies.

A mu-metal shield surrounds the caliber allowing an anti-magnetic protection to an intensity of 1,000 Gauss (80,000 A/m). Also, BALL’s patented Amortiser® system absorbs energy created by external shocks and makes sure every component stays intact in case of harsh impact.

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 H₃ gas tubes. H₃ gas is encapsulated in glass micro tubes and light energy is released when the molecules strike the internal colored surface of the tubes.

Without any form of charging, the luminosity shines automatically and combats the black expanse of any environment. Notably, for the first time, the tubes are placed underneath the bezel for an uncluttered design. To complete visibility, micro gas tubes have also been placed on the dial and the hands for a total of 36 tubes.

The Engineer Master II Diver Chronometer is offered with either a classic mix of green and yellow tubes or a more modern rainbow-colored combination.

With a thickness of only 13.5mm, the 42mm stainless steel 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.
