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 240o. like a fan opening to reveal a second hand-decorated dial. Developed on the basis of its "Tourbillon Double Balance Spring" calibre, this complication opens and closes the dial by the fan-like rotation of two opaque sapphire crystals. A Swiss invention patent has been filed for it (No. 701 406 A1, delivered on July 3, 2009). For more information on:
