Urwerk’s new EMC watch (“Electro Mechanical Control”) is comprised of a manually wound movement, as well as an electronic rate monitor. I was given a sneak preview of the UR-EMC caliber back in May at Baselworld which left me scratching my head, but now we have a complete picture.
Watch aficionados well know that changes in position and temperature, as well as shocks, can all adversely affect the isochronism (timing regularity) of a wristwatch. What Urwerk has done with the EMC is enable the wearer to not only obtain the precise timing rate on demand, but also to then use that information to accurately adjust the precision of the watch. Capability of this sort is the preserve of professional watchmakers and their Witschi machines, but now anyone with an EMC watch will now have similar capability thanks to the watch’s incredibly complex hybrid electronic/mechanical architecture.
These things said, while I can appreciate the concept, for a watch that will reportedly sell for around $120,000, it all seems a bit frivolous to me. You can decide what you think of the Urwerk EMC after reviewing the pics and info below.
Urwerk EMC Watch
43mm width x 51mm length x 15.8mm height satin-finished titanium and steel case
Hours, minutes, seconds; precision delta, power reserve indicators
The Precision indicator (upper left) provides an instantaneous display of precision expressed in +/- seconds per day.
EMC’s monitoring unit is powered by a micro-generator — several cranks on the lever and electrical energy generated is stored in a super capacitor (incorporated into the case)
UR-EMC calibre conceived, developed and manufactured by URWERK
Swiss lever escapement with ARCAP P40 linear balance wheel coupled to an optical sensor, vertically mounted double mainspring barrels (connected in series) for 80 hrs power reserve, Côtes de Genève, snailing, micro-bead blasting, polished bevels on screw heads
The balance is made of ARCAP — a non-magnetic and anti-corrosive material. Its dimensions and shape have been carefully calculated to optimise data from the optical sensor, maximize aerodynamic efficiency and minimize loss of amplitude.
Maxon® generator with manual winding charging super capacitor for EMC system (Optical sensor controlled by an integrated circuit board; 16’000’000hz reference oscillator)
When activated, a tiny optical sensor on the balance wheel captures the precise rate of oscillation of the 4 hertz / 28,800 vph regulator for a period of 3 seconds. This sensor consists of a transmitter and a receiver positioned either side of the balance, and is triggered manually (after charging the super capacitor) by pressing a button on the left side of the case.
