A fundamental technical achievement, humbly setting a milestone in watchmaking history.

A chronometer for our time, more enduring and reliable, for true everyday chronometric accuracy.

What are they saying about us?

« We are witnessing a new era of chronometry: modern materials and new approaches. Bernhard Lederer, and his Central Impulse Chronometer, is a further step in the research of the “energy lossless” escapements. This ideal might never be reached, but the journey is fantastic. We can only applaud the determination and assiduous work of master watchmaker Bernhard Lederer. His work can be a fruitful source of inspiration for generations to come. The Central Impulse Chronometer is a fabulous example of exceptional technical design in an appealing presentation. The watch, besides its extraordinary mechanical complexity, is an exquisite and elegant piece. »

In this regard, Bernhard Lederer follows through in the footsteps of George Daniels, and lays his own. Engineering prowess remains the foundational core of the Central Impulse Chronometer.
