In 1793 Abraham-Louis Brequet invented the very first connected device pairing wristwatch and a clock. In the spirit of Breguet’s inspiration of more than 220 years ago, Urwerk has designed and is producing AMC (Atomic Master Clock). AMC is the very first master-slave clock and wristwatch, in which an atomic clock, via a complex mechanical linkage, duplicates all of the functions of Breguet’s most advanced sympathique clock in one device.
The atomic master clock component of the Urwerk AMC weigths approximately 35 kilos and the case is in solid aluminum.

The clock is a dual oscillator type in collaboration with TIMEstandard, using rubidium and YIG (Yttrium Iron Garnet). This master clock rewinds the Urwerk wristwatch, set it to the correct time and if necessary adjust its rate. This world first brings together in a single mechanism all the functions of the various sympathique clocks produced by Abraham-Louis Breguet with an atomic mother clock.

The watch is a novel construction and is designed specifically for the AMC project. It includes typical Urwerk features such as the power reserve indicator and two stacked barrels for a power reserve of four days. But the most ingenious features, through unseen to the unaided eye, are revealed upon close examination of the movement. The watch was designed to fit on and work with its base.
