This November, the prestigious Monaco-based Only Watch 2023 charity auction will witness the unveiling of a truly mesmerizing timepiece, the ArtyA Purity Moissanite. This exceptional creation not only introduces a brand-new architectural Manufacture movement but also showcases a groundbreaking case material never before used in watchmaking.

To showcase its innovative Manufacture movement, independent watchmaking brand ArtyA has taken on a monumental challenge. They've developed a unique case material using Moissanite, a precious stone discovered in 1893 within a meteorite crater. Despite its unparalleled beauty, Moissanite's exceptional hardness, with a Mohs scale rating of 9.5 (second only to diamond), makes it incredibly challenging to machine. It boasts a melting point of 2,730 degrees Celsius and around 52.1 Gigapascals of sustained pressure, equivalent to more than 500,000 ATM. These properties make the Moissanite case the most resilient ever used in the world of horology.

Moissanite's origin, deep within a meteorite crater, adds to its allure. After extensive work on various aspects of sapphire glass, including the development of color-changing NanoSapphire Chameleon, ArtyA turned its attention to the aesthetic qualities of this exceptional stone. Unique processes had to be developed to machine this silicon carbide of extraterrestrial origin, hailing from outside our solar system. Dr. Henri Moissan, who named this mineral in its natural form, originally discovered Moissanite.

What sets the ArtyA Purity Moissanite apart is its unparalleled brilliance. With a dispersion index twice that of diamond, this Moissanite case presents an extraordinary rainbow effect, amplified by its 600 facets (compared to the 58 facets of a traditionally cut diamond). The meticulous faceting creates the illusion that the movement is suspended within a perfectly cut gemstone. With every movement of the wrist, this timepiece reveals a captivating symphony of colors.

The heart of this unique timepiece is the new ArtyA Purity Manufacture movement. A descendant of the Purity Tourbillon family of high complications, this movement boasts a 4Hz balance with inertia block. It represents three years of dedicated work, a collaborative effort between ArtyA and Telos, aimed at delivering a caliber that is uncompromising, reliable, and generous. The movement's bridges are designed for visual harmony, with circular shapes and a layering pattern that showcases the craftsmanship behind this skeletonized marvel.

Telos, renowned for its expertise in high-quality watch movement design and production, joined forces with ArtyA in this creative and dynamic partnership. Together, they've pushed the boundaries of excellence by combining traditional watchmaking artistry with the latest technological advances. This collaboration not only opens new horizons but also creates unique timepieces that are sure to captivate enthusiasts worldwide.

ArtyA, a 100% independent brand founded in Geneva in 2009 by Yvan Arpa, is known for its exploration of unconventional materials and exclusive designs, combined with reinvented grand complications. ArtyA's timepieces are unique cult objects, designed for an audience that values exceptional authenticity, creativity, and craftsmanship. Their slogan, "Manufacture of Emotions," encapsulates their passion for creating prestigious and emotionally resonant timepieces.

The ArtyA Purity Moissanite represents a leap into the future of watchmaking, where innovation meets beauty in a unique and unprecedented way. This extraordinary timepiece is a testament to ArtyA's commitment to pushing the boundaries of horological artistry.
