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 the 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.
