ArtyA pushes its Purity Tourbillon into sport territory with a limited run of nine pieces. The proposition is stark yet refined – a full sapphire Wavy case wrapped around an in-house, fully skeletonised tourbillon calibre built for poise and pace. At CHF 130’000, it asks to be judged on construction, not theatrics.
The movement is an exclusive ArtyA manufacture with double parallel barrels and central hours, minutes, and seconds, plus running seconds read on the tourbillon itself. The flying tourbillon spans 18 mm, among the largest in high-end watchmaking, turning once per minute and beating at 4 Hz, 28’800 vph. The scale is intentional – a broader cage that aims at better dynamic stability and shock resistance. A variable-inertia balance handles fine regulation, and the twin barrels deliver a 70-hour reserve.
Finishing shows intention rather than flourish. Advanced skeletonisation leaves bridges with pronounced, hand-polished bevels that catch light with clean edges. The barrels carry personalised engraving. Nothing feels hidden, which suits a watch that prefers mechanical honesty over stagecraft.
The Wavy case is cut entirely from Absolute Sapphire, chosen for its optical purity and hardness of 9 on the Mohs scale, about 1’800 Vickers. At 44 mm, with a screwed open sapphire back and sapphire crown, it is a clear vessel for the movement and little else. Scratch resistance sits in rare air – third only to diamond and moissanite – though water resistance remains a sensible 30 meters.
Colour enters with restraint. A visible caseback gasket and matching strap provide the chromatic accent, swappable at an ArtyA retailer. Four launch options – deep red, luminous orange, deep blue, electric turquoise – let one piece shift character without touching the movement or the crystal case.
There is a quiet design logic at work. The circle leads everything – tourbillon, bridge flow, case silhouette – a simple geometry pressed into service of clarity. The result reads as a manufacture tourbillon that welcomes contemporary life rather than shrinking from it. Power is visible. Precision is felt. That is enough.
