Lederer presents the new Central Impulse Chronometer with a diameter of 39mm

Initially presented in a 44mm case, this horological masterpiece embraces a new era with a smaller, more contemporary 39mm size. This evolution is not merely a matter of size; it marks a significant mechanical advance with the introduction of a new triggering system for the constant-force remontoirs, designed and developed in-house at Lederer’s Saint-Blaise (Neuchâtel) workshop.  Every aspect, from the 18% reduction in the movement’s thickness to the new synchronization of the seconds hands, represents a significant technical challenge, expertly mastered.

“When you alter the geometry of an escapement, there are significant technical implications and it triggers a domino effect. Developing the Central Impulse Chronometer in a 39mm size was not merely about reducing the diameter; the movement’s height had to be brought down, too, to preserve the aesthetic balance. Every aspect and detail had to be meticulously assessed as to whether a redesign was warranted. “

The difference in diameter is immediately obvious; less so the real highlight: the new detent mechanism for activating the remontoirs. Developed entirely in-house, this redesign significantly enhances the watch’s reliability and performance.

An interesting aspect of this dial’s design lies in Manufacture Lederer’s ability to also produce its own dials, hands, and indices in-house, thus ensuring not only exceptional quality but also adherence to delivery schedules.
