One of the most acclaimed watchmaker’s of our time, Bernard Lederer is renowned for his dedication to improving the mechanical escapement. Taking inspiration from past Masters, such as Breguet and more recently George Daniels, his re-imagining and innovation of the natural escapement for use in wristwatches has resulted in an improvement in stability and accuracy that has have become a benchmark standard within the industry. 

Complex in its conception, the Lederer Central Impulse Chronometer Calibre is conceived to deliver optimal precision by having the most direct connection between the escapement and the balance, the movement features two separate gear trains, each of which are individually energised by a dedicated barrel, and which terminate at the two escapements, giving the mechanism visual symmetry. Configured either side of a pivoting anchor, each escape wheel is governed by its own ten second remontoir, a tiny spring at its centre, which stores and then releases its energy in alternating bursts, as they regulate the oscillations of the large titanium balance wheel between them. The Lederer Triple-Certified Observatory Chronometer is the latest Masterpiece that is equipped with the Patented Lederer Chronometer Escapement movement, which notably has received validation from three independent Observatories in Glashütte, in Besançon and in Geneva.

The model is presented in a 44mm case with a height of 12.20mm, manufactured from 904L stainless steel. Gentle flowing lugs enhance its profile, while the bezel is trim to enable a full disclosure of the façade. Crafted in the Lederer atelier, the dial is of solid sterling silver and is rendered with a pristine white tone that recalls the purity of a fresh fall of snow. Achieved using an ancient technique that requires multiple steps, its understated surface belies the complexities of the movement that lies beneath.

Heat blued and offering incredible contrast against the silvery white dial, the hands are superb, with openworked examples for the hours and the minutes. Uniquely, the minutes hand finishes with a tiny pointer that enables a precise and fascinating reading of the 10-second intervals of the remontoir. The recessed small seconds subdial is fitted with its own little blued hand and the geographical coordinates of the three observatories are engraved within - a subtle reference to the precision of the watch that adds a delightful touch of depth to the arrangement. To finish, a ‘V’ symbol at the upper is inspired by the meridian sign recalling the significant and intimate links between the Lederer atelier and chronometric excellence.

A model that represents an exclusive opportunity to acquire a timepiece of exceptional refinement, the Lederer Triple-Chronometer Observatory Chronometer watch is presented in a limited edition of only 8 pieces. Each watch in the series will be delivered with three observatory certificates with each uniquely marked using the 8 cardinal directions on the Wind Rose engraved onto the back.
