The changing color case, made according to an innovative and avant-garde process developed by ArtyA, is adorned by a transparent dial hand-decorated with real leaves of the Amazon jungle, some fragments of butterfly wings and gold leaves. In the background, you will discover the ArtyA golden “shams” skeletonized manual movement. A green porosus strap adds the finishing touch.

As you may have admired with our first ArtyA Purity Tourbillon Chameleon, ArtyA is currently developing Nano-sapphire cases capable of changing color depending on the light. In natural light, the “Chameleon” case has a yellow color, but when exposed to artificial light (6500K or above), the case instantly and completely changes color to a translucent, mysterious green.

This unique work of ArtyA’s creators Yvan Arpa and Dominique Arpa-Cirpka, for the dial, will delight afficionados of exceptional masterpiece.

The new ArtyA Nano-Sapphire watch case is an optically transparent polycrystalline material that is formed by the crystallization of glass with a unique chemical composition, and the result greater physical and chemical properties than the original glass.

This material is one of many glass-ceramic materials, which have been around for more than 50 years and have a wide range of compositions and applications, using a multi-component high temperature composition on the base of two main oxides – SiO2 and Al2O3. These oxides are key components of most natural gemstones. A temperature of 1700 °C. (compared to 700°C for glass) is needed to synthesize this material, and only one company in the world has adapted this existing technology to create a material specifically optimized for watches and jewelry. And ArtyA is the first company to use it in a watch case.

This case material has incredible hardness, 7 on Mohs scale, which is much higher than glass (5 on the Mohs scale), which guarantees the durability of this incredible case material.
