Quick TakeForget just telling time; this Flying Regulator Jumping Hour puts on a show! Crafted from warm 18-karat red gold, it's got this immediate presence, but the real magic happens when you look closer. That bezel isn't just functional; it's a halo of 72 meticulously set diamonds, catching light from every angle. Then your eyes dive into the dial – a multi-layered spectacle. The base, shimmering white gold completely paved with nearly 500 diamonds over a traditional guilloche pattern, forms a dazzling stage. Floating above this icy sparkle are the regulator displays, but with a twist: forget a creeping hour hand. Precisely at the top of the hour, the number in the 12 o'clock window snaps instantly – a satisfying mechanical jump that’s pure Chronoswiss ingenuity. Blued 'Feuille' hands sweep across the offset minute track and small seconds, adding a touch of classical contrast to the glittering extravagance below. It's a timepiece that balances technical prowess, luxurious materials, and a truly unique way of marking the hours, all powered by the reliable Caliber C. 283 automatic movement.

DescriptionManufacturing specifications detail an 18-karat red gold case construction, identified by reference CH-8321RD-SIDSI, comprising 28 individual components. Dimensional parameters define the case diameter at 40 mm and the height at 11.85 mm, accommodating a strap interface width of 20 mm. The case incorporates a screw-down case back, finished with a satin texture and fitted with a flat sapphire crystal for viewing integrity. Case surface treatment involves a combination of polished sections and areas with a vertical satin finish, complemented by a characteristic onion-style crown. A prominent feature is the polished screw-down bezel, engineered with side knurling and a full thread; this component is elaborately set with 72 diamonds, possessing a total weight of 1.05 carats, classified as Top Wesselton (TW) color and Very Very Slightly Included (VVSI) clarity. Water ingress protection is rated at 3 bar, equivalent to a depth of 30 meters.

Powering the timekeeping functions is the Caliber C. 283, an automatic movement operating at a frequency of 4 Hz, corresponding to 28,800 alternations per hour (A/h). This mechanism provides a power reserve of approximately 42 hours and incorporates 28 jewels. The movement's finishing includes nickel-plated bridges adorned with circular graining and spiral offsets. Visible through the case back is the gold-plated rotor, which has been skeletonised and engraved, featuring Geneva Stripes decoration and mounted on a ball bearing system for efficient winding. Time indication deviates from traditional analogue displays, utilizing a digital jumping hour shown in an aperture positioned at 12 o'clock, an off-centre minute hand, and a small seconds sub-dial located at 6 o'clock. The dial architecture is a complex multi-level design; the foundational layer is crafted from 18 ct. white gold, lavishly set with 491 diamonds (TW colour, VVS clarity, totalling 1.9 carats) arranged over a signature guilloche pattern. Above this, the upper dial level presents a satin finish and is mounted securely on screwed plinths. Hands are of the "Feuille" shape, thermally blued, polished, and curved, with the minute hand specifically bent by hand. Attachment to the wrist is achieved via a hand-sewn Louisiana alligator leather strap secured by a pin buckle.
