Originally created to equip the famous Frecce Tricolori flight team, the Chronomat has constantly evolved over the years, both technically and aesthetically, while retaining its unique style characterized by the rotating rider tab bezel. The A1335611 C645 372A self-winding Caliber 13 mechanical movement has a power reserve of 42 hours and has been certified as a highly precise chronometer by the Controle Officiel Suisse des Chronometres (or COSC, the official Swiss chronometer inspection body). This Breitling A1335611.C645.372A is topped by a ratcheted rotating bezel, and the blue dial includes luminous markers, luminescent hands (with signature Breitling seconds hand), a date window at 3 o'clock, and three silver subdials. The chronograph can measure events to 1/4 of a second, and features 30-minute and 12-hour totalizers. This A1335611-C645-372A is matched to a stainless steel band. Breitling watches are all equipped with scratch-resistant sapphire crystals and glareproofed on both sides, which eliminates 95 percent of the reflections perceived by the naked eye.
