s one of the first brands in 2016 to adopt sapphire crystal for its watch cases, ArtyA quickly made it an essential choice: the material offers both perfect transparency, enabling the beauty of mechanical movements to be admired from every angle; and remarkable scratch resistance, enabling exemplary durability and longevity. Sapphire is a crystal with an extraordinary hardness of 9 on the Mohs scale, making it the third hardest natural material after diamond and moissanite on the Mohs scale. (Traditional glass, by comparison, rates a 5.5.)

Sapphire has always been used for its protective virtues and the positive energy it radiates.

While ‘round’ is the shape usually associated with a watch, ArtyA seizes opportunities to think outside the box, proposing new shapes – including the so-called “tonneau” which owes its name to the French word ‘barrel’.

Generous spatial volumes and shapes, cut from a block of sapphire crystal that perfectly fits the wrist: ArtyA’s years of experience in the field have made it possible to create this sophisticated case with a bold look that stands out from the conventional.

The arched, profiled sides of ArtyA’s new Curvy Purity Tourbillon present a design that is both elegant and technical. The rounded angles amplify the presence of the 17mm 4Hz tourbillon floating in its center at 6 o’clock, whilst the case remains harmoniously sized at 38.5 x 43mm. The curved shape of the whole, a design by Jérémie Arpa, Yvan and Dominique Arpa’s son, explores new possibilities, with softer, more ergonomic lines than on round or rectangular models.

The fruit of the close collaboration between Artya and La Chaux-de-Fonds movement maker Télôs, the Curvy movement is the latest addition to ArtyA’s family of Purity Tourbillon Manufacture calibers, here entirely redesigned to fit the singular tonneau-shaped watch case.

Recognisable by its remarkable axial symmetry and the crown positioned at 12 o’clock, the Curvy Purity Tourbillon movement might be considered as the culmination of the collection.

The assertively sized 17mm flying tourbillon has been positioned at 6 o’clock to allow an ideal view of its rotation. Thanks to the double barrel mounted in parallel, it offers an appreciable 72-hour power reserve.

Above the double barrel, the dial showcases ArtyA’s meticulous approach to skeletonisation. Here, cast-iron sandblasting and hand-bevelling serve to subtly optimise the display of time indications for clear legibility.
