The Electro-Mechanical Control (EMC) which URWERK designed over the course of 6 years to improve the chronometric precision of the movement — was originally unveiled in titanium in 2013 — and is now going to be available in a black DLC treated titanium and steel case.
Their goal was achieved with a special 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 4Hz 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, with improved accuracy.
