WHITE GOLD CASE – MIXED TECHNIQUES DIAL

This spectacular and highly technical piece conceals an ingenious complication.

Beneath its classic wristwatch appearance lies a mechanism conceived and developed by Laurent Ferrier: a device that pivots the dial’s two opaque crystals a full 240° like a fan opening to reveal a second hand-decorated dial.

Developed on the basis of the Tourbillon Double Balance Spring calibre, this complication opens and closes the dial by the fan-like rotation of two opaque sapphire crystals. A patent has been filed for this invention.

The dial window opens on demand. By pressing a push-button placed on the crown, the two opaque sapphire crystals pivot instantly and reveal the secret dial.

The dial window also opens automatically or in passing. The mechanism is automatically activated for an hour each day, at the specific time chosen by its owner and adjusted by a watchmaker during movement assembly. Just as when the sun is rising or setting, it takes a full hour for the dial to be fully revealed or concealed.

This already complex mechanism outright defies the laws of horological construction. Crafting it calls for meticulous gestures and rigorous testing, and its precision stems from exceptional adjustment.
