The EMC by Urwerk is the world’s first precision mechanical watch in which the timing can be both monitored and adjusted by the user to suit their lifestyle.
Changes in position and temperature, as well as shocks, can all adversely affect the isochronism (timing regularity) of a wristwatch.
Thanks to EMC’s unique and pioneering monitoring unit, not only can the wearer obtain the precise timing rate on demand, they can then use that information to accurately adjust the precision of their watch to suit their own personal rhythm.
In mechanical watches, the precision of the timepiece relies on its balance wheel, an internally-housed regulator which rotates back and forth, turning the watch’s energy a precise number of times per hour.
In the isolated environment of the watchmaking atelier, all timepieces are adjusted to fit an average consumer, regardless of their surroundings. Yet, outside factors – like changes in altitude, temperature and humidity – also affect a watch’s precision.
So that’s why there will be differences in accuracy between someone wearing the same watch on the hot-baked streets of Abu Dhabi or in the frigid backwoods of Alaska, and on the wrist of a couch potato in front of the TV and on a long-distance runner. So what does this mean specifically?
Well, the watchmaker’s best friend is a device called a Witschi, which listens to the rhythm of the balance and displays the performance of the movement, how much a movement gains or loses in 24 hours.
The EMC essentially has a Witschi built into it (electronic, though manually wound!) so that the wearer sees how his watch is running. And, the EMC offers the wearer the ability to adjust the watch on the fly to keep chronometric performance at its peak.
The EMC features a deconstructed dial with four separate indications. A clockwise tour of the displays, from top left, presents the:
- The on-demand, precision indicator (instantaneous rate delta δ) ranging from -20 to + 20 seconds per day
- Seconds dial with counter-balanced seconds hand
- Hours and minutes
- An 80-hour power reserve indicator.
Turning EMC over reveals the fully in-house movement with the integrated circuit board – the EMC ‘brain’ –, the top of one of the two mainspring barrels nearthe crown and the top of the balance wheel and optical sensor on the winding handle side.
