Jaquet Droz Quantième Perpétuel Céramique

Posted on by

With the Quantième Perpétuel Céramique timepiece from the prestigious Hommage La Chaux-de-Fonds 1738 Collection, Jaquet Droz makes a strong statement about its avant-garde identity in the world of Haute Horlogerie. Skilfully housing this famous complication in an ultra-contemporary case, the Manufacture from La Chaux-de-Fonds, Switzerland, remains true to the ultimate aspiration of generations of superior craftsmen: to achieve simplicity.

A complication that transcends Time, the Quantième Perpétuel marks the passing of the days of every month, whose number changes in leap years. Its prodigious mechanical memory has become an obsession with the most exacting of connoisseurs and master craftsmen. Perpetuating house traditions dating to 1738, Jaquet Droz has endowed this exclusive model with its customary technical superiority and purity of lines.

For the watchcase, the Manufacture has pushed the possibilities of the ceramic material to their limits while keeping the shrinkage index under perfect control. The master dial-makers showed similar technical genius, working to specifications that demanded nothing less than perfection. For this Numerus Clausus of 88, they demonstrated the full measure of their talent by creating an opaline black dial adorned by a black gold ring with a fine-brushed finish.
