Today, URWERK unveiled “the world’s first precision mechanical watch in which the timing can be both monitored and adjusted by the user to suit their lifestyle.” The Electro Mechanical Control (EMC)¬†movement was designed over the course of 6 years, with the goal to improve accuracy and precision.

The goal was achieved with a specially developed balance and barrels. The balance wheel is made from ARCAP, which is a non-magnetic, corrosion-resistant alloy of copper and nickel. The geometry of the balance wheel maximizes aerodynamics and minimizes loss over time. It beats at 4 Hz and is powered by dual barrels that are vertically mounted on a single shaft. The result is an 80-hour power reserve with consistent power delivery, thus improving chronometry (timekeeping accuracy).

According to Felix Baumgartner, the EMC incorporates a Witschi-like measuring instrument in the watch to allow you to obtain reliable and accurate data on your timepiece at the touch of a button. With the information, you can fine-tune the watch, by yourself, without needing to go to your watchmaker. (Please see the diagram below for operating information.)
