The innovative architectural and symmetrical themes of the movement are woven into the overall design of the Central Impulse Chronometer, in its dial, hands, indexes and case. The harmony of the whole makes every element essential, and classical aesthetics underline the uncompromising watchmaking vision of Bernhard Lederer.
The craftsmanship and passion of decorators and watchmakers will forever be kept between the sapphire crystals, reaffirming the singularity of human creation and giving to each timepiece its unique character.
