Tiny Purity Tourbillon Chameleon

Artya, a sapphire alchemist, has succeeded in developing NanoSapphire, a technology that colors this polycrystalline material. This research led to a world first, never seen before in the watchmaking industry: the NanoSapphire Chameleon. A true revolution, this case has the ability to change color depending on the temperature of the light. The "Chameleon" case reflects a first color, amber-orange for this piece, in natural light, while when exposed to artificial light (6500 Kelvin or more), it instantly changes color to a wonderful green.

To integrate such a case, an exceptional movement was required: the Tiny Purity Tourbillon. Its elder sister, the Purity Tourbillon, underwent a reduction of 7mm to become the masterpiece that is the Tiny Purity Tourbillon Chameleon.  Following a complete overhaul of the movement, this most compelling of high complications timepiece has been reduced from an imposing 46 mm to a light, airy 39 mm in diameter. To make this possible, the dial was moved to 3 o'clock in this fully skeletonized edition. Under this modern dial, we find the double barrel mounted in parallel. These barrels have  retained their original size to maintain an exceptional 72-hour power reserve. The tourbillon now benefits from a traditional adjustment with a fixed piton that replaces its entire raquetterie. The tourbillon cage has been entirely hand-bevelled to an exceptional finish.
