ArtyA Showcases the New Curvy Purity Tourbillon Movement, Redesigned for a Tonneau Case

The shape of a watch case can be generally described as being round, square or rectangular. In the craft of fine watchmaking, it has been observed that the round shape is most widely used. This is simply because that’s the shape a watch’s balance wheel takes. Sometimes, watchmakers prefer to think outside the box when it comes to case shapes and materials. Take ArtyA. The brand has now launched the latest Curvy Purity Tourbillon watch with a tonneau-shaped, sapphire crystal case, limited to only 13 pieces. In fact, ArtyA is one of the first watch brands to adopt sapphire crystal for cases.

Sapphire crystal is, basically, pure aluminium oxide that has undergone a process of crystallisation. Among all other materials, sapphire crystal is deemed the most scratch-resistant. Another benefit of sapphire crystal is that it brings clarity or transparency to dials. Furthermore, it is one of the most expensive materials available in the market; high prices may make watch enthusiasts think twice before opting for sapphire crystal. Most timepiece makers use anti-reflective coating as sapphire crystal shows high reflectivity.

The latest Curvy Purity Tourbillon watch comes in a 43 mm tonneau-shaped case, crafted from sapphire crystal. This limited-edition watch gets a crown positioned at 12 o’clock. The movement, created in collaboration with Telos, has been redesigned to fit the tonneau-shaped watch case. The skeleton dial comes with a 17 mm flying tourbillon, positioned at 6 o'clock, to allow for an ideal view of its rotation. The upper tourbillon bridge and the cage are cast in iron, sandblasted, and hand-bevelled.

Beneath the time-viewing dial are the double barrels. One can also spot a time-viewing subdial with satin finishing for the minute bridge. The dauphine hour and minute hands come on a skeleton subdial. Powering the watch is a double-barrel tourbillon movement, offering a 72-hour power reserve.

This power reserve is possible because of the double-barrel torque with a 4 Hz frequency, which is higher than the usual torque for a tourbillon, thereby ensuring greater stability. Turning the watch over showcases the open screw-in caseback. Finishing the Curvy Purity Tourbillon watch is a recycled leather strap with a pin buckle. Avoid water activities while wearing this watch as it has a water resistance of only 30 metres.
