An Apogee of European Watchmaking

Abraham-Louis Breguet was born in Neuchâtel, Switzerland, in 1747 but moved to Paris in 1775. A peerless technician, Breguet invented mechanisms that constituted wonderful advances in watchmaking, notably the tourbillon regulator, an astonishing device that corrected the effect of gravity on the balance wheel.
Watches, clocks, and measuring instruments, accompanied by portraits, archive documents and patent applications, shed light on the developments pioneered by Breguet from his early years in Paris to the period when he handed the business over to his son, Antoine-Louis.
