Laurent Ferrier Secret Oil on Canvas WHITE GOLD – FIREWORKS 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.
