esigned over two and half centuries ago, the Grande Seconde by Jaquet Droz never ceases to amaze. Its “Skelet-One” skeleton version, presented in 2018, marked yet another break: it was the first time the Grande Seconde did away with its dial. In its place: light, lightness and transparency.
- The Grande Seconde Skelet- One Ceramic’s movement features blued steel screws to join the 18-karat white gold hour circle and the sapphire dial. The movement plate stretches all the way around the case, which itself does away with the casing ring. With this new construction, the gear train is entirely suspended and fixed to the skeletonised bridges that cross over the movement.
Today, the piece returns with a new feature that gives it added modernity: a ceramic case. With a diameter of 41.5 mm, it’s in perfect harmony with the Grande Seconde Skelet-One’s open movement structure, featuring a black coating that intensifies its power and modern, masculine character.
Its straight lines contrast with the ceramic case’s skillful finishing, with a satin-finished top just like its lugs. In contrast, its polished sides foster a play of light that is amplified by a double sapphire “glass box” on the top and bottom, offering the largest possible opening onto the skeleton movement.
