UR-Chronometry

The AMC

In the spirit of Breguet’s inspiration of more than 220 years ago, URWERK starts designing and producing 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 clocks in one device: it would wind, set and regulate an URWERK watch, which rests in a cradle in the case of the atomic clock itself.

Swiss timepieces Chronometry watch AMC

This world first brings together in a single mechanism all the functions of the sympathique clocks produced by Abraham-Louis Breguet.

The atomic master clock component of the URWERK AMC weights approximately 35 kilos and the case is in solid aluminum. 

This master clock rewinds the URWERK wristwatch, set it to the correct time and if necessary adjust its rate.

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. 

The watch also has URWERK’s oil change indicator.

Meticulous
craftmanship

For a decade, URWERK pushes the limits of mechanical possibilities, resulting in the development of extremely sophisticated time-measuring instruments. After the EMC, URWERK has continued investing, testing, failing and recovering in its relentless progress...
Here its latest and certainly most ambitious project so far. The AMC.
