Maximizing light

To mark its 280th anniversary, Jaquet Droz is introducing a first within its Grande Seconde collection, of which the two off-centered hours and minutes dials, together with the large seconds display, form the figure 8. The new feature of the Grande Seconde Skelet-One lies in the use of sapphire in a skeleton-type composition, the purpose being to allow light to flood into the watch. To achieve this, Jaquet Droz has completely openworked the plate and the gold oscillating weight, while eliminating the casing ring. The use of sapphire for the offset dials enables an entirely transparent view of the multi-layered JD 2663 SQ skeleton movement. Totally translucent and bearing only discreet markings swept over by an extremely slender hand, the disconcerting large seconds disk enables the gaze to plunge into the inner workings of the movement below. Surrounding the two dials is the ample space characteristic of all Grande Seconde models, to which the tapering blackened bridges of the Skelet-One lend a decidedly contemporary structure. Alongside this 41.5mm black ceramic version, the Grande Seconde Skelet-One also comes in white or red gold variations with a 41mm case and leather strap.
