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 castiron 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.
- 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 Hhorlogerie. The balance wheel’s inertia is precisely adjusted via peripheral weights, resulting in perfectly regular hairspring oscillation and sustained longterm chronometric precision over time.
Curvy Ruby Case: The Alchemy of Savoir-Faire
Building on years of experience and pioneering material innovation, ArtyA once again pushes the boundaries of contemporary watchmaking with a case that is both sophisticated and distinctive.

- Radiant Ruby Sapphire Crystal: Sharing the same chemical composition as natural ruby, this extraordinary material proudly showcases the Geneva maison’s signature vermilion hue.
- Where Hardness Meets Hue: Retaining all the characteristics of clear sapphire crystal, this case offers the material’s legendary hardness (9 on the Mohs scale) while adding striking chromatic depth and elegance.
- Spectacular Luminescence: Under UV light, the ruby-red hue becomes vividly incandescent— an intrinsic property of ruby that lends the watch a mysterious aura.
United to Transform Lives
Helping, giving, and supporting are essential actions that embody the feeling of solidarity with those in distress. Grand or modest, these actions can bring hope and comfort, transforming lives. To be human is to show empathy and compassion — to actively seek to support those in need, to ease their daily struggles and help build a better future.

Philippe and Elisabeth Dufour shared: “We all come
from somewhere, we all have a story, and we can all be bearers of hope.
Beyond differences in color, culture, belief, and ethnicity, we all
suffer in the face of adversity. Suffering knows no boundaries, and
neither does poverty. In the face of these hardships, we are all equals.
We do not claim to save the entire world, but together, we can make a
difference. May tears be transformed into optimism with our selfless
help, and may every heart, where boundless kindness resides, remind us
of our shared humanity. We extend our heartfelt thanks to the
watchmaking community that supports our cause and shares our values for
this second charity auction, as well as to Phillips in Association with
Bacs & Russo and their entire team. With them, we are confident that
the spirit of solidarity will continue to thrive.”
