Urwerk has just announced that they’re working on what sounds like a very unusual (and extremely technically) challenging project: a modern version of a Breguet sympathique, controlled not by a high precision mechanical clock, but by a portable atomic clock. The sympathique clocks of Breguet were among his most complex creations: a clock with a recess (a dock, if you will) for a pocket watch. Once per day, the clock, via a complex series of mechanical linkages, would do three things: set the watch to the correct time, wind it, and (the most complex challenge) regulate the rate of the watch. According to Urwerk, the AMC (Atomic Master Clock) project aims to duplicate this functionality, but with a portable atomic clock connected to an Urwerk watch movement via mechanical linkages.
