Quick TakeOkay, let's talk about wrist presence. The CH-8321R-BKBK isn't just telling time; it's putting on a little show every hour, on the hour. That digital jump at 12 o'clock? Pure mechanical theatre. Combined with the classic regulator layout separating minutes and seconds, it forces you to appreciate time differently. It’s less about a quick glance and more about engaging with the intricate dance of gears reflected on the dial. And speaking of the dial, that 3D construction isn't just for show – it adds incredible visual depth, especially with the rich guilloche pattern anchoring the design beneath the satellite minute and second displays. Encased in warm 18k red gold, the whole package feels substantial yet refined. The mix of polished and brushed finishes, the knurled bezel, the onion crown – it all speaks to a certain old-world charm, but the jumping hour and regulator display keep it firmly planted in the realm of sophisticated, slightly avant-garde watchmaking. It’s a conversation starter that balances technical prowess with undeniable style.

DescriptionThe construction of reference CH-8321R-BKBK utilizes 18-karat red gold for the primary case material, assembled from 28 distinct components. Overall case dimensions measure 40 mm in diameter and 11.85 mm in height, with a standard band width accommodation of 20 mm. Case finishing incorporates both polished and vertically satin-finished surfaces for visual contrast, complemented by a traditional onion-style crown. Security and water resistance are ensured by a screw-down case back, featuring a satin finish and a flat sapphire crystal exhibition window, along with a polished screw-down bezel characterized by side knurling and a full thread engagement. Water ingress protection is rated at 3 bar, equivalent to a depth of 30 meters. This specific configuration focuses on material integrity and precise dimensional specifications suitable for its intended application.

Powering this timepiece is the Caliber C. 283 automatic movement, operating at a frequency of 4 Hz, which translates to 28,800 alternations per hour (A/h). The movement provides an approximate power reserve of 42 hours when fully wound and incorporates 28 jewels for reduced friction. Finishing details include nickel-plated bridges adorned with circular graining and spiral offsets. Visible through the case back, the gold-plated rotor is skeletonised, engraved with Geneva Stripes, and mounted on efficient ball bearings. Time indication is unconventional: a digital jumping hour is displayed prominently in an aperture at the 12 o'clock position, while minutes are shown off-centre, and a small seconds sub-dial resides at the 6 o'clock position. The dial itself presents an elaborate, multi-level construction; the lower level features a galvanised guilloche pattern, while the upper dial elements exhibit a satin finish and are mounted on screwed plinths, creating significant depth. The hands are "Feuille" shaped, crafted from red gold-plated material, diamond-cut or lacquered, and possess a distinct curve, with the minute hand being meticulously bent by hand. Attachment to the wrist is achieved via a hand-sewn Louisiana alligator leather strap, available with either a pin buckle or a folding clasp. A key characteristic remains the complex three-dimensional dial architecture highlighting the signature guilloche work.
