Founded 1860 by Édouard Heuer in Saint-Imier, Switzerland, Heuer quickly established itself with innovations like its first chronograph in 1882 and the patented "oscillating pinion" in 1887—still used in modern mechanical chronographs.
 
The brand has long been intertwined with motorsports. Models like the Autavia, Carrera, and Monaco (introduced in the 1960s) became iconic chronographs favored by professional drivers and even worn by Steve McQueen in Le Mans.
