ArtyA unveils an avant-garde horological creation: “Purity Wavy HMS Mirror” A fully in-house caliber reimagined through masterful handcraftsmanship. The perfect union of design and comfort, encased in the groundbreaking Wavy case, crafted from titanium with a transparent protective DLC coating. The first-ever mirror casebackStairway To Heaven: The Movement At the heart of this exceptional timepiece, ArtyA’s latest in-house caliber: Stairway To Heaven HMS. This manual-winding movement embodies the Manufacture’s dedication to both visual spectacle and horological excellence: • Microbead-frosted and hand-chamfered minute wheel train and balance bridges. • Pulsing at 4 Hz, the spectacularly “starified” escapement is positioned like a podium centerpiece, suspended in mid-air. • Traditional fine regulation – a hallmark of haute horlogerie that ensures optimal precision. This process involves meticulously adjusting the balance wheel’s inertia using peripheral weights (inertia blocks) to maintain the hairspring’s steady and consistent oscillation. The result: optimized caliber performance and lasting chronometric stability. • Twin barrels, working in parallel, equipped with longer, finer mainsprings for a more stable and linear energy release. The polished barrel blade reduces friction for improved efficiency. The redesigned drum barrels, with fluid, curving lines, seamlessly integrate with the bold bridge architecture of the movement. Proudly bearing the manufacture’s name and caliber designation, this subtle detail completes the movement’s refined aesthetic. Wavy Titanium Case A bold evolution in the Wavy collection, this is the first case crafted from grade 5 titanium, a material prized for its strength and lightness. • Ultra-light yet incredibly strong, titanium embodies both modernity and innovation, delivering exceptional comfort without compromising durability. • The matte finish results from meticulous hand polishing, followed by microbead frosting for a refined texture. • A transparent DLC coating boosts resistance to scratches, shocks, and fingerprints. For comparison, stainless steel has a Vickers hardness of 200 HV, titanium 400 HV, and transparent DLC-treated titanium an impressive 1,200 HV (1,800 HV for the black DLC version). • A mirror-polished lug-to-lug contour adds a discreet yet sophisticated touch, enhancing the timepiece’s elegance without diluting its avant-garde appeal. This meticulous finish – exceptionally complex to achieve on titanium – creates a striking contrast with the case’s matte surface, balancing power with refinement. • Designed by Jérémie Arpa, son of Yvan Arpa, the case embodies independent, family-driven watchmaking at its finest. Its flowing, organic contours evoke the power of ocean waves, an effect heightened by titanium’s natural opacity – delivering a case design unlike anything seen before in haute horlogerie.

Mirror Effects The Wavy Titanium’s mirror caseback introduces an unprecedented innovation, a world first in watchmaking: • A fully reflective surface that offers a striking new way to experience the movement. • From the front, seeing through to the mirrored bottom creates the illusion of depth, with the movement seemingly floating in space, enhancing the ethereal purity of the skeletonized caliber’s aesthetic. • From the back, the one-way mirror effect teases the complexity of the movement without fully revealing it complexity, adding an element of mystery and sophistication. ­
