After the steel model and the red gold limited series, Breitling has introduced this triple time zone chronograph, inspired by a watch from the 1950s-1960s, in an all-black new livery accentuating its original and timeless style. The steel case is coated with a high-resistance carbon-based treatment, and it features an ultra-hard and scratch-resistant ceramic bezel. The dark touch continues on the dial featuring tone-on-tone counters, as well as on the original rubber strap picking up the design of the steel mesh Aero Classic bracelets. The case is water-resistant to 100 m (330 ft) and its back bears a depiction of the stylized planes that were a longtime Breitling signature. The Chronoliner combines the two functions most useful to pilots and globetrotters: a chronograph to measure flight times and a triple time zone display to juggle with the time around the world. The second time zone in 24-hour mode (useful for distinguishing between day and night) is indicated by a red-tipped central hand, while the bidirectional rotating bezel with its star-shaped cut-out that facilitates handling, serves to read off a third time zone, also in 24-hour mode.
