The Jaquet Droz Grande Seconde Moon Swiss Serpentinite, available in a Limited Edition of 88 Pieces continues the legacy, spirit of innovation and the aesthetic refinement of its founder, Pierre Jaquet-Droz and reinforces the 8 modern core values of the 281 year old heritage atelier.

Having used everything from aventurine to extraterrestrial meteorite, the natural brilliance of Serpentinite now joins the latest Grande Seconde Moon Swiss Serpentinite Limited Edition of 88 Pieces.

Jaquet Droz Grande Seconde Moon Swiss Serpentinite Limited Edition of 88 Pieces

Since its resurgence, Jaquet Droz has focused on its 8 core values, among them – the brand’s dedication to exotic mineral elements in limited editions. The Jaquet Droz Grande Seconde Moon Swiss Serpentinite embodies that watchmaking ethos – making Serpentinite front and centre of this objet d’art. The dial of the newest Grande Seconde Moon takes hewn slices of rock from the sheer slopes of the Matterhorn, near the Hörnli Hut, the legendary base camp of the first ascent of the Matterhorn in 1865 and imbues the exquisite dress watch with a spirit of adventure.

The face of this limited edition Jaquet Droz Grande Seconde Moon Swiss Serpentinite appears as if a scaly-rock with a texture comparable to snake skin, complemented perfectly by the sub-seconds and date dial with an aperture for the resplendent moonphase complication. The Serpentinite moon disc blends perfectly into the dial, punctuated beautifully by the hyper-realistic textured 22K white gold moon and 18K white gold stars.

The heart of the Grande Seconde Moon Swiss Serpentinite beats the Jaquet Droz in-house caliber 2660QL3 features a silicon balance spring with a  power reserve of 68 hours but its true raison d’etre lies with a astronomical instead of a horological moonphase. The former is technically distinct for its 135-tooth moon disc compared to 59 for a horological moon phase. As such, it guarantees a degree of accuracy requiring correction only every 122 years and 46 days.

While it is highly unlikely that one would ever touch the dial of their newest Grande Seconde Moon (nor would they want to – the material is especially brittle and easily scratched, a testament to Jaquet Droz artisans), it’s interesting to note that Serpentinite is peculiarly soft to the touch.
