Blancpain is a Swiss watch manufacturer founded in Villeret in 1735 by Jehan-Jacques Blancpain, making it the oldest registered watch brand in the world. It is headquartered at Le Brassus and Paudex and owned by the Swatch Group. Its principal collections are the Fifty Fathoms, Villeret, Le Brassus, Air Command and Ladybird. The Fifty Fathoms of 1953 established the template for the modern dive watch - rotating locking bezel, high water resistance, luminous markers and antimagnetic protection - and Blancpain has never made a quartz watch.
