he Grande Seconde line is the cornerstone of traditional fine watchmaking by Jaquet Droz. One member of this collection, the Skelet-One, has been instrumental in the Swiss brand’s embrace of the 21st century: a bold, creative timepiece, yet firmly rooted in its heritage.

Now Jaquet Droz unveils two new versions of its Grande Seconde Skelet-One, honouring two complementary stylistic approaches.

The traditional model features a case made of red gold, a gold alloy with subtle warm coppery accents. The modern version, on the other hand, marks the first time Jaquet Droz has used plasma ceramic on one of its timepieces.

This material is made by transforming white ceramic with gas heated to 20,000°C, giving it a unique metallic glow without adding any metal fragments to the process. It is just as hard, lightweight and scratch-resistant as high-tech ceramic.

Inside the 41 mm case of the Grande Seconde Skelet-One lie the delicate workings of the Jaquet Droz 2663 SQ selfwinding skeleton mechanical movement with silicon balance spring and pallet horns.
