ArtyA, the Geneva independent founded by Yvan Arpa, has never been shy. Its watches tend to lead with attitude, and the Complexity is the most technically serious thing the brand has made. Presented earlier in 2026, it introduced a world-first layout of two inclined tourbillons, one at 12 o'clock and one at 6, linked by a differential. The new Complexity Métiers d'Art keeps that architecture unchanged and instead pushes the hand-finishing to the front, so the piece reads less as a stunt and more as a craft object.
The same mechanics, dressed by hand
The idea behind the Complexity is worth restating, because the Métiers d'Art edition leaves it intact. The calibre carries two Conillon regulators, each following a conical rather than a cylindrical path, which helps average out the effect of gravity across the vertical positions. They sit at 12 and 6 o'clock, turn in opposite directions, and complete a rotation every 30 seconds. A differential distributes energy between the two and averages their rates, so the watch runs on the mean of its two escapements rather than one.
What changes is the surface treatment. The finely sandblasted dial base is entirely hand-engraved, a burin cutting individual radiating lines across it. The applied indices are given hand-polished bevels, with their flanks drawn on the carbon buff and their upper faces left sandblasted so they sit into the texture instead of shouting over it. The movement gets the same attention: shot-blasted upper surfaces, hand-hammered lower surfaces worked into a relief, every angle bevelled and polished by hand, hand-perlage in the mainplate recesses around the differential, and a polished moulding framing the centre bridge. Black rhodium plating darkens the ground so the polished edges catch the light.
A case cut from crystal
The case is the second half of the spectacle. It is cut from a solid block of synthetic sapphire, measuring 42mm by 48mm and 13mm thick, with a triple-concave middle that follows the wrist better than the numbers suggest. Sapphire domes at 12 and 6 o'clock rise over the two tourbillons and magnify them, so the case itself is part of the mechanism on show. The crown is faceted and also cut from crystal. ArtyA says the geometry takes more than 120 hours of diamond machining and over 140 hours of polishing, which is the kind of figure that explains the price before the movement is even counted.
Movement and numbers
The manual-winding Calibre Complexity-01 was developed with Purtec Sarl in Vallorbe. It is built from 287 components with 44 jewels, beats at 21,600 vibrations per hour, and holds 50 hours of power. With the tourbillon cages included, the movement stands 14.1mm tall, which is why the case needs its domes.
Price and availability
The Complexity Métiers d'Art is worn on an integrated rubber strap with an ArtyA folding clasp. The sapphire version is limited to nine individually numbered pieces at CHF 190,000, available by order through ArtyA Genève and official retailers. A version in pigeon-blood synthetic ruby is offered at CHF 220,000. It is a small run of a difficult object, and it is squarely aimed at the collector who already owns the serious independents and wants something louder to sit beside them.
