Quick TakeTalk about a conversation starter! This Chronoswiss doesn't just tell time; it puts on a show. Forget sweep seconds, the star here is that snappy digital Jumping Hour at 12 – click! – a precise, instant change that's pure mechanical theatre. Framed in luscious 18k red gold, the whole piece radiates warmth and classic luxury. But look closer... that dial isn't flat. It's got levels, man! The depth achieved with the upper satin-finished dial floating over that intricate guilloche base layer is seriously cool, drawing your eye right in. Then you've got those gorgeous, heat-blued feuille hands adding a pop of vibrant color against the silvery dial texture. The off-center minutes and small seconds keep the regulator spirit alive, prioritizing minutes but doing it with modern flair. It’s powered by a solid automatic movement, visible through the back, reminding you of the intricate engine driving this unique display. It’s less a tool, more a kinetic sculpture for the wrist, blending old-school craft with a clever complication.

DescriptionComponent analysis of the reference CH-8321R-SISI reveals a case constructed from 18-karat red gold, comprising 28 individual parts. The principal housing dimensions are a diameter of 40 mm and a height of 11.85 mm. Integration with the strap is achieved via a standard 20 mm band width. Case finishing involves a dual aesthetic: surfaces are partly polished and partly feature a vertical satin finish. Functional elements include a traditional onion-style crown and a screw-down case back, the latter exhibiting a satin finish and incorporating a flat sapphire crystal for movement observation. The bezel is a polished, screw-down type, characterized by side knurling and a full thread engagement mechanism. Water resistance is rated at 3 bar, equivalent to a depth of 30 meters, providing protection against minor water ingress. Powering the timekeeping functions is the automatic Caliber C. 283 movement.

Operational frequency for the Caliber C. 283 is specified at 4 Hz, which corresponds to 28,800 alternations per hour (A/h), contributing to the precision of the time display. The movement provides a power reserve of approximately 42 hours when fully wound. Within its architecture are 28 jewels, minimizing friction at critical points. Movement finishing includes nickel-plated bridges adorned with circular graining and spiral offsets. The rotor, responsible for automatic winding, is gold-plated, distinctively skeletonised, engraved with Geneva Stripes, and mounted on a ball bearing system for efficiency. Time indication is presented via an elaborate dial constructed on two levels. The foundational level features a galvanised guilloche pattern, while the upper level presents a satin finish and is mounted securely on screwed plinths. The display configuration includes digital jumping hours positioned at the 12 o'clock location, an off-centre minutes display, and a small seconds sub-dial situated at 6 o'clock. Hands are designed in the "Feuille" shape, thermally blued for color, polished, and meticulously curved, with the minute hand undergoing a hand-bending process. Securing the watch to the wrist is a hand-sewn Louisiana alligator leather strap, offered with either a pin buckle or a folding clasp mechanism. A defining characteristic remains the multi-layered 3-D dial construction.
