The Central Impulse Chronometer is the first Chapter of the Masters of Escapements series. Inventing a new, reliable, self-starting, energy-efficient, wristwatch-compatible and high-accuracy escapement is the pinnacle of watchmaking.
The Central Impulse Chronometer escapement is based on a pair of escape wheels that interact with a special titanium anchor of a unique shape and optimal geometry. The impulse positions, angles and contact timing are designed to dramatically lower friction and therefore increase longevity. The sounds of the double impulse, and the sound when liberating the remontoirs, working alternately, provide the Central Impulse Chronometer with a unique, complex acoustic signature.
The energy to power the movement is transmitted from two barrels via two independent gear trains, each linked to a dedicated escape wheel. In addition, Bernhard Lederer has integrated a remontoir d’égalité into each of the two gear trains to accumulate a buffer stock of energy in a small spring close to the escapement.
Each remontoir is recharged at 10-second intervals and ensures the energy delivered to the balance wheel varies very little. Furthermore, the two remontoirs operate alternately one after another, separated by 5-second intervals, so each one offsets variations in the other.
Bernhard Lederer’s Central Impulse Chronometer perfects the works of two of the most respected past Masters, Abraham Louis Breguet and George Daniels, with respectively their Natural Escapement and Independent Double-Wheel Escapement.
“My watches are for those who not only admire the beauty of a timepiece but also cherish the intricate cratsmanship and the pursuit of perfection behind it. It’s about offering something exceptional to collectors who value both tradition and the progression into modernity.” – Bernhard Lederer
