User friendliness, readability, ergonomics; while functio- nality is an essential attribute of all Breitling instruments for professionals, the Chronospace has adopted it as supreme value. Witness an impressive list of functions: 1/100th of a second chronograph with split times, alarm, countdown, dual timezone with independent alarm, UTC and perpetual calendar. The large-sized dial fea- tures oversized hands and an extremely effective NVG- compatible backlighting system enabling night-time read-off. This pilot's instrument is also equipped with a rack-and-pinion mounted slide rule that is easily and accurately operated by rotating the star-shaped bezel. The double-caseback construction is designed to amplify the audible signals emitted by the SuperQuartzTM caliber so as to reach 90 decibels. The originality of the design is accentuated by the steel mesh bracelet or perforated rubber strap.
