This new addition to the ArtyA’s Complication Collection features a fully transparent crystal case in order to maximize the magic and beauty of the exclusive Double Barrel Manufacture Flying Tourbillon movement.
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.
This complication timepiece comes 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.
Fully transparent, the sapphire crystal case offers the breathtaking views of the skeletonized horological engine. Each part of the movement is delicately bevelled and polished by hand. The skeletonized bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
The innovative design of the case fully exploits the luminescent potentials of the Laboratory created corundum, a sapphire-like gem sharing its many unique qualities. The case is stubbornly scratch proof because of the remarkable hardness of sapphires – 9 on the Mohs Hardness Scale.
