Purity Stairway To Heaven HMS Wavy

A standout launch at Watches and Wonders 2024, the Purity Stairway to Heaven movement continues to astonish. Initially presented with two off-center hands on variously colored dials, it now features a central three-hand display. The inclusion of a prominent central second hand adds even more vibrancy to this dynamic movement.

This HMS evolution represents a major technical breakthrough, preserving the three-dimensional architecture of the original Stairway To Heaven movement and showcasing the power of its mechanics:

- Two barrels operate side by side, in parallel, using a longer, finer spring for stable, linear energy delivery and improved winding efficiency.
- A ‘stellar’ escapement, placed as if on a "Stairway To Heaven" podium and suspended in mid-air at 4Hz, creates a visually stunning aerial spectacle. The balance wheel has been scaled down to boost its chronometric accuracy.
- Arched, hand-beveled bridges with innovative shapes are directly integrated, rather than being juxtaposed or adjacent, creating the necessary space for the regulating organ.
- Extreme skeletonization defines each component, providing visual focal points and requiring machining with uncompromising precision and perfect alignment.
- The traditional spiral adjustment caters to clients seeking customization and distinctiveness, featuring tiny weights adjusted in reversed symmetry to optimize the spiral’s inertia.
- Visually, the architecture masterfully manipulates material and void, creating tension among components. The entire mechanism is built around the precise positioning of the gears, designed as if suspended in mid-air.

For the debut of this revolutionary movement, a case that reflects the DNA of the Geneva-based watchmaker was essential. Designed by Jérémie Arpa, son of Yvan Arpa, the Wavy sapphire crystal case takes inspiration from the iconic Curvy model. Its barrel shape has been replaced with a round 40 mm design, yet it retains its distinctive lines and reflections. This new sapphire crystal watch offers unique refractive angles to fully appreciate all aspects of this skeletonized movement.
