Franck Muller has long been synonymous with horological daring, and the Round Triple Mystery is no exception. Nominated at the 2025 Grand Prix d’Horlogerie de Genève in the prestigious Ladies’ Complication category, this creation blends gem-set artistry with technical brilliance and delivers a spectacle of light, motion, and invention.
Housed in a 39mm rose gold case, the Round Triple Mystery is entirely set with 357 diamonds—totaling 5.86 carats—arranged in a hypnotic spiral that draws the eye to its most compelling feature: three independent rotating discs that mysteriously indicate hours, minutes, and seconds. Each triangular marker traces its own celestial path, transforming time into a ballet of movement and reflection. The seconds disc, adorned with a triangle-cut diamond, adds a poetic rhythm that underscores the passage of time with elegance and precision.
The technical achievement is as remarkable as the aesthetics. To power three discs without sacrificing accuracy, Franck Muller’s engineers embraced extreme lightness: The skeletonized central disc weighs a mere 0.052 grams, with elements as light as 0.002 grams, crafted from aluminum for strength and efficiency. Bridges just 0.3mm wide showcase mechanical finesse at its most delicate. The central plate, patterned like a spirograph, enhances the visual poetry of perpetual rotation.
More than a watch, the Round Triple Mystery is a declaration of imagination—an embrace of time’s enigma rather than its resolution. By fusing high jewelry with inventive mechanics, Franck Muller delivers a masterpiece that reminds us that mystery is not always to be solved, but to be savored.
