New: ArtyA Curvy Purity Tourbillon

The ArtyA Curvy Purity Tourbillon will retail at CHF 135,000 / EUR 141,000 / USD 152,000 (excluding tax).


We first covered ArtyA with the news and commentary on the AquaSaphir earlier this year. In this novelty, the case is made entirely from sapphire glass in a tonneau shape. The case looks like it is sculptured out of a block of ice. The transparency of the case is remarkably clear. The movement, made in collaboration with Telos, is laid out symmetrically with the crown at the 12 o’clock position the twin barrels flanking the canon pinion which drives the hour minute dial at the upper part of the case. The tourbilllon takes center stage below with its carriage looking larger than the skeletonsed hour and minute sub-dial.

As with the AquaSaphir, the movement is described as exclusive made in Switzerland. The movement looks good, with a rather aesthetically pleasing architecture and design. The finishing specifications call for contrasting finissage from mirror-polished surfaces and satin finished to diamond polished sides.

Interestingly, the tourbillon cage is sandblasted with cast iron, an unusual choice for the delicate component. The cage is hand beveled, and from the photographs look very nice.

Release information

As 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.

The illusion of simplicity

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 Curvy Purity Tourbillon movement, redesigned for a Tonneau case 

The fruit of the close collaboration between Telos and ArtyA, 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.

Recognizable 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 skeletonization. Here, cast-iron sandblasting and hand-beveling serve to subtly optimize the display of time indications for clear legibility.
