This L.U.C Engine One Tourbillon model houses a proprietary mechanical hand-wound tourbillon movement, L.U.C Calibre 1TRM. In much the same way as a car engine, this movement is mounted on silent blocks – that absorb shocks – and held by three lever arms inserted into the case middle. This L.U.C Calibre 1TRM designed, developed and produced by Chopard Manufacture beats at a cadence of 28,800 vibrations per hour and boasts a 60-hour power reserve. Chronometer-certified by the COSC, a sure token of reliability and precision, this tourbillon movement drives displays of the hours, minutes, seconds and the power reserve.
