The Franck Muller Round Double Mystery model is a breathtaking display of horological artistry and technical innovation. Housed in a 39mm round case crafted from 18k Rose Gold and hand set with 194 brilliant-cut diamonds (2,43 carats) and 216 brilliant-cut colored sapphires, this timepiece captivates with its opulent elegance and enigmatic charm. At the heart of the watch lies Franck Muller’s signature “Double Mystery” complication, a mesmerizing system in which both the hour and minute hands appear to float mysteriously around the dial without any visible central connection.
The dial itself is a masterwork of design, adorned with concentric rotating discs and hand set with 218 brilliant-cut diamonds (1.56 carats) and 14 indexes made of colored sapphires, rubies and tsavorites (0.98 carats).
Powered by a finely tuned & meticulously decorated automatic movement, the Round Double Mystery is not only a visual marvel but also a high-precision timekeeper. Paired with a luxurious hand-stitched alligator strap and a matching diamond-set buckle, this exceptional watch represents the pinnacle of Franck Muller's ability to combine mechanical mastery with extravagant design.
