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.)
