Revolutionary dual-escapement chronograph capable of measuring 1/100th of a second. Features two independent gear trains with separate balance wheels and barrels. The timekeeping portion runs at standard El Primero 36,000 vph (5Hz), while the chronograph escapement runs at an extraordinary 360,000 vph (50Hz), allowing the central chronograph seconds hand to complete one revolution per second in 100 discrete steps. Both balance wheels use carbon-matrix carbon nanotube composite for lightness and magnetism resistance. The chronograph has its own 50-minute power reserve wound separately via the crown. Chronometer-certified by TIME LAB.
