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.
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.
