CENTRAL IMPULSE CHRONOMETER (CIC) 39MM

Lederer’s CIC 39 embodies creative freedom and technical precision, delivering a new contemporary elegance. 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.

Central Impulse Chronometer
CIC 9016.50.303 (white gold, blue dial)

Movement
Mechanical with manual winding, dual impulse escapement
Number of components: 212 ; Number of jewels: 36 rubies
Frequency: 21,600 vibrations per hour (3 Hz)
Diameter: 35mm Thickness: 4.95mm

Features
Two independent escape wheels at the end of two separate gear trains, each equipped with its own 10-second constant-force remontoir.
These wheels operate alternately, achieving a remarkable symmetry. With a detent mechanism that is absolutely one of a kind –its profile, its rubies, its lift angle, its direct central impulse, the result is a truly extraordinary system. This design minimizes friction and ensures the balance wheel receives energy with optimal timing, enhancing isochronism and stability.

Winding stem with two positions:
Position 1: manual winding
Position 2: time setting
Stop-seconds for time setting
