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 16.3 mm which is 50% larger than most existing tourbillons. Since the ArtyA Purity tourbillon beats at a rate of 28’800 vibrations per hour, extraordinary accuracy and greater stability are achieved through a much higher frequency than many other high-end Swiss tourbillons. 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. Fully transparent, the sapphire crystal case has nothing to hide and plenty to show. This quest for transparency takes to the extremes the skeletonizing of the movement and enhances the astonishing beauty of its intricate spirit.
