    The Double Tourbillon Technique 30° Bi-Color, an original and innovative interpretation of the brand's first fundamental invention, the Double Tourbillon 30°, reconfigures its architecture in a diametrically opposed style, while providing a demonstration of mechanical skill.

    The unique architecture draws you right into the mechanism. The synthetic sapphire-crystal is a kind of window looking onto an animated miniature world, a veritable jigsaw of pieces that takes your eye from one set of gears to the next. The details of each component reveal themselves as your gaze explores the timepiece.
