THE SECRET OF HIGH RATE ACCURACY.
A stately mainspring barrel stores the ample power reserve of 60 hours. And high rate accuracy is assured by the large balance wheel with eccentric poising weights that is reciprocated by a Lange balance spring developed and manufactured in-house. It beats at a frequency of 18,000 semi-oscillations per hour.

THE FLYBACK MECHANISM.
The flyback mechanism is based on the complex interaction of many individual parts. When the reset push piece is pressed during an ongoing time measurement, a system of levers interrupts the flow of power to the chronograph mechanism. With its two contact surfaces, the heart lever engages the zero-reset heart cams that carry the sweep-seconds hand and the minute-counter hand, causing them to jump to zero. Releasing the push piece instantaneously starts the new measurement.FLYBACK ANIMATION (MOV 2.0 MB)
