Gentleman's Breitling Chronomat BO1

Breitling is a brand of Swiss watches produced by Breitling SA, a private company originally founded by Léon Breitling in 1884. The watchmaker offers high-end Certified Chronometers designed primarily for aviation use. All Breitling watches are manufactured in Switzerland and are made from Swiss components. Raw movements are obtained from ETA and Valjoux and are modified in the Breitling Chronometrie Workshops, before undergoing COSC (Contrôle Officiel Suisse des Chronomètres) certification. As of 2009, Breitling now makes a manufacture movement, designed, manufactured and assembled completed in-house.
