Baume & Mercier Watches started in 1830 when the Baume family were making watches in the Jura near Berne. It as not until 1918 when a member of the family met Paul Mercier, a Geneva jeweller of high repute. In 1980 the Riviera sports watch par excellence made of gold and steel was first made. To test its durability and precision, the watch was mounted on the wheel of a BMW M1 before the start of the Le Mans 24 hour race. The watch endured the speed, heat and weather and ran perfectly after the race.
