Luxferity, 18.09.2025

The Grand Prix d’Horlogerie de Genève (GPHG) has revealed the nominees for its highly anticipated 2025 edition, with the Round Triple Mystery™ honored in the prestigious Ladies’ Complication category. This recognition places the timepiece among the most distinguished creations in contemporary haute horlogerie.
A World Premiere In Haute Horlogerie
First unveiled in April 2025 at the World Presentation of Haute Horlogerie, the Round Triple Mystery™ immediately captivated collectors and connoisseurs with its singular vision of timekeeping. Defined by three rotating discs for hours, minutes, and seconds, the watch offers a mesmerizingly enigmatic reading of time.
Rattrapante R.U.R.
Set entirely with diamonds, the watch is an exceptional union of fine watchmaking and high jewelry artistry, a radiant testament to Swiss technical mastery and aesthetic sophistication.
A Diamond-Encrusted Masterpiece
Encased in 39mm rose gold, the Round Triple Mystery™ exudes sculptural boldness balanced with mechanical finesse. Its hypnotic dial is set with 357 diamonds totaling 5.86 carats, forming a spiral of brilliance that draws the gaze to three rotating triangular indicators.
Plissé - Pearl White
Each rotation is both a technical performance and a visual poem: emerald-traced paths transform the passage of time into a celestial ballet of light and motion.
Technical Innovation At Its Core
The challenge of powering three independent discs—especially the ultra-light fast-rotating seconds disc—was met with extraordinary ingenuity. Crafted from aluminum for ultimate lightness and rigidity, the skeletonised central disc weighs only 0.052 grams. Even the tiniest elements, such as the arrow (0.002 g) and diamond-set seconds indicator (0.003 g), were engineered with micromechanical precision.
Plissé - Rose
Bridges as fine as 0.3 mm exemplify the watch’s delicate architecture, demonstrating a harmony between aesthetic daring and technical prowess.
The Geometry Of Time
At the center, a single diamond is set within an intricate spirograph-inspired pattern. This geometric design reflects the continuous rotations of the three discs, echoing the cyclical essence of time while amplifying the brilliance of the gem-set dial.
Plissé - Ivory
A triangle-cut diamond serves as the poetic seconds hand, embodying the rhythm of time as a perpetual dance.
More Than A Timepiece
The Round Triple Mystery™ transcends the conventional role of a watch. It is a story of defiance and imagination, where mystery is not to be solved, but savored. Each rotation transforms the reading of hours, minutes, and seconds into an emotional experience, celebrating invention, artistry, and the eternal allure of mystery.
