ArtyA Purity Tourbillon Chiaroscuro

The latest edition of the ArtyA Complications collection, the ArtyA Black Purity Tourbillon feature a steel case with a black PVD treatment to house its spectacular exclusive manufactured double barrel flying tourbillon with rose gold treated bridges.

For the development of these magnificent mechanisms, Franck Orny and his team joined Yvan Arpa and his team in a constructive complementarity of skills, a sharing of values and a beautiful creative vibratory dynamic.

As an expression of ArtyA’s horological grammar, the Purity Tourbillon displays a technical inventiveness that combines a maverick style with visual clarity. A beautifully balanced architectural ensemble, the manually wound caliber features an over-sized flying tourbillon with a diameter of 17 mm which is at least 50% larger than most existing tourbillons.

Since the ArtyA Purity tourbillon beats at a rate of 4 HZ, extraordinary accuracy and greater stability are achieved through a much higher frequency than many other high-end Swiss tourbillons (usually 2 or 3HZ).

Equipped with a power-reserve of 70 hours, the two barrels connected in parallel, fuel the movement that operates the central hour and minute functions while the indication of the seconds is elegantly displayed on the flying tourbillon that rotates 360 degrees in 60 seconds.

Mounting the barrels in parallel reduces the thickness of the spring for more stable torque. But also improves the delta of the barrel spring curve, with an ideal ratio between power reserve, performance and regularity.

ArtyA has chosen to manufacture this timepiece with a free-sprung balance with variable inertia:

  • This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks and during movement assembly or disassembly, hence better chronometric results over time.
  • Each part of the movement is delicately beveled and polished by hand for an extreme skeletonizing.
  • The skeletonised bridges were subjected to intensive and complete validation tests to optimise their resistance capacities, they are also treated in rose gold treatment.
