Breitling SA (German pronunciation: [bʁaɪtliŋ]) is a Swiss watchmaker based in Grenchen, Switzerland. Breitling designs, engineers, manufactures and distributes chronometer watches. Breitling is a privately owned company founded in 1884 inGrenchen, Canton of Solothurn, Switzerland. Breitling is known for precision-made chronometers useful to aviators.
Breitling SA was founded in Saint-Imier, Bernese Jura by Léon Breitling in 1884.
Breitling watches are made in Switzerland using Swiss components. Breitling makes two movements: the calibre B01 and calibre B04, a B01 with an added GMT module.ETA and Valjoux are the primary suppliers of ébauches used in certain Breitling watches. The ébauches are completed in the Breitling Chronometrie Workshops before undergoing COSC (Contrôle Officiel Suisse des Chronomètres) certification.
In 2009 Breitling developed the B01, a mechanical chronograph movement, used in the Breitling Chronomat 01, the first watch produced entirely by Breitling. The Chronomat has ever since used a Breitling movement with the latest addition (2012) to the range being the Chronomat GMT Limited, a limited edition watch; and the Breitling Chronomat 44 GMT, both with the B04 movement.
