Lederer Central Impulse Chronometer 39mm Black Rhodium RG | Pre-Order

For collectors drawn to avant-garde haute horlogerie with refined architectural design, the Central Impulse Chronometer (CIC) 39mm Black Rhodium RG by Bernhard Lederer represents a breakthrough in contemporary mechanical watchmaking. As the first creation in the Masters of Escapements series, this high-complication timepiece reimagines the escapement with a patented dual impulse mechanism—an evolution of concepts pioneered by Abraham-Louis Breguet and George Daniels. Driven by two independent barrels and gear trains, the movement delivers precisely timed impulses to the balance via a custom titanium anchor, while twin remontoirs d’égalité recharge every 10 seconds in alternating 5-second intervals to maintain constant force. The watch is housed in a 39mm case of 5N rose gold, with a domed sapphire crystal caseback revealing the movement in full. The sand-blasted black rhodium dial, featuring interlocking figure-eight subdials, evokes perpetual motion and the technical harmony that defines true luxury watchmaking.

Entirely developed and finished in-house, the CIC’s hand-wound calibre is a feat of horological engineering, composed of 212 components, 36 rubies, and measuring just 4.95mm thick. Its three-dimensional construction showcases openworked bridges, proprietary wheel spokes, and extraordinary finishing—hand bevelling, graining, frosting, engraving, and satin-polishing—executed to the highest standards of haute horlogerie. The dual escapement system dramatically reduces friction, enhances durability, and gives the watch a distinctive sonic signature with its alternating double impulse sound. Beating at a classic 21,600 vibrations per hour (3 Hz) and offering a power reserve of 38 hours, the CIC 39mm Black Rhodium RG is both a technical marvel and a collector’s showpiece, blending precision, innovation, and artisanal excellence in a rose gold luxury mechanical watch.
