Lederer Unveils the Central Impulse Chronometer 39mm

Geneva Watch Week, April 2024: Lederer, renowned for its innovative timepieces, presents the new Central Impulse Chronometer 39mm, marking a significant milestone in horological craftsmanship. Following its prestigious Innovation Prize win at the Grand Prix d'Horlogerie de Genève in 2021, the Central Impulse Chronometer continues to captivate with its avant-garde mechanism and now a more refined, sober aesthetic presented in a 39mm diameter case.

This new creation represents a complete reinvention of technical innovation and design for the Central Impulse Chronometer, pushing the boundaries of conventional watchmaking while preserving traditional expertise. The updated appearance of the Central Impulse Chronometer 39mm embodies modern elegance, perfectly in tune with contemporary trends.

The journey towards the Central Impulse Chronometer 39mm involved a meticulous rethinking of its movement, resulting in a remarkable reduction in thickness by over 18%.

"Developing the Central Impulse Chronometer in a 39mm size was not merely about reducing the diameter; every aspect and detail had to be meticulously assessed to preserve the aesthetic balance and ensure exceptional precision."

Bernhard Lederer

Inspired by pioneering work in watchmaking history, Bernhard Lederer revisited escapement design from a modern perspective, culminating in a truly extraordinary system that minimizes friction and optimizes energy delivery to the balance wheel. The result is unparalleled isochronism, stability, and precision throughout the power reserve.

The design of the Central Impulse Chronometer 39mm reflects Lederer's commitment to harmonizing technical excellence with timeless aesthetics. The slender case, available in white or rose gold, features a stunning dial design that emphasizes depth and complexity, mirroring the sophistication of the movement within. Every component, including dials, hands, and indices, is meticulously crafted in-house, ensuring exceptional quality and adherence to Lederer's standards of excellence.

The Central Impulse Chronometer 39mm is not just a timepiece; it's a celebration of innovation, precision, and artistic expression. With limited editions available in both white and rose gold variants, each limited to 20 pieces, this masterpiece is a testament to Lederer's unwavering dedication to pushing the boundaries of watchmaking.

"Crafting such exceptional work under a 44mm case, complete with Mr. Lederer's signature transparent case back, is already a remarkable feat. However, scaling down the entire mechanism to fit into a 39mm case diameter elevates the watch industry to an unprecedented level of innovation and precision."
