Purity Curvy Tourbillon
A manufacture tourbillon caliber
The standard-bearer of the Purity manufacture collection, the Curvy Tourbillon represents the pinnacle of ArtyA’s skeletonization mastery. Engineered to integrate seamlessly into a tonneau case with a crown at 12 o’clock, this one-off creation epitomizes the creative audacity that defines the Geneva maison.
The Curvy Purity Tourbillon Caliber
This high-complication movement is the third developed by the independent brand. Designed to fit the tonneau form to perfection, it now appears in its most accomplished iteration, showcasing outstanding finishes:
-
All bridges are frosted with cast-iron microbeads and meticulously beveled by hand.
-
Two barrels operate in parallel, each fitted with longer, slimmer springs for optimal unwinding and steady torque, ensuring stable, linear energy transmission. The polished blade minimizes friction, while the newly curved design of the barrel drums flows seamlessly with the movement’s prominent bridges.
With its expert mastery of sapphire crystal workmanship, ArtyA presents a "shaped" Tourbillon watch with a new tonneau-shaped case of sleek, ergonomic construction.
-
The Purity Tourbillon movement has been entirely redesigned to fit the tonneau shape of the case. With its perfect axial symmetry and crown at 12 o'clock, it is the fruit of collaboration between the ArtyA and Telos teams.
As one of the first brands in 2016 to adopt sapphire crystal for its watch cases, ArtyA quickly made it an essential choice, as the material offers both perfect transparency, enabling the beauty of mechanical movements to be admired from every angle, and remarkable scratch resistance, enabling exemplary durability and longevity. Sapphire is a crystal with an extraordinary hardness of 9 on the Mohs scale (5.5 for traditional glass), the third hardest natural material after diamond and moissanite on the Mohs scale.
Sapphire has always been used for its protective virtues and to benefit from the positive energies it spreads.
The illusion of simplicity
While the vast majority of watches are round, ArtyA can easily think outside the box by proposing new shapes, including the so-called "tonneau".
Its generous volumes and shapes, cut from a block of sapphire crystal that fits the wrist perfectly, and ArtyA's years of experience in the field have made it possible to create this sophisticated case with a bold look that stands out from conventional watches.
Its curved, profiled sides create a design that is both elegant and technical. The curved angles allow double appreciation of the immense 17 mm 4Hz tourbillon floating in its center at 6 o'clock. The case is harmoniously sized at 38.5 x 43 mm. The curved shape of the whole offers an interesting alternative, with its softer, more ergonomic lines than round or rectangular models, a design by Jérémie Arpa, son of Yvan Arpa.
With years of expertise in crafting avant-garde cases, ArtyA continues to push the boundaries of form and function.
This creation achieves a perfect alchemy of cutting-edge technology and refined aesthetics – elevating the visual experience and magnifying every instant on the wrist.
-
An 18 mm flying tourbillon beating at 4 Hz—a frequency notably higher than that of most tourbillons—delivers maximum chronometric stability. Positioned at 6 o’clock, this mechanical marvel offers an ideal vantage point to admire its mesmerizing rotation.
-
Traditional fine adjustment: The fixed-stud tourbillon is regulated using a time-honored approach reserved for haute horlogerie. The balance wheel’s inertia is precisely adjusted via peripheral weights, resulting in perfectly regular hairspring oscillation and sustained long-term chronometric precision over time.
