Quick TakeForget boring time-telling; the Chronoswiss Flying Regulator Jumping Hour CH-8325-BKBK is a mechanical spectacle for the wrist. That instant click as the hour jumps digitally at 12 o'clock is pure watchmaking theatre, a delightful complication that never gets old. It’s housed in this tough-looking black DLC case, giving it a modern, almost stealthy vibe. But the real star might be the dial – it’s got layers! Seriously, the depth created by the two levels, with that intricate guilloche pattern on the bottom, pulls you right in. The off-centre minutes and seconds add to the regulator layout's functional asymmetry. It feels less like a simple watch and more like a kinetic sculpture, powered by the reliable Swiss automatic Caliber C. 283 humming away inside. Strapped on with that embossed calfskin, it’s a statement piece that blends classic mechanics with contemporary design and a dash of avant-garde attitude.

DescriptionThe CH-8325-BKBK model features a case constructed from stainless steel treated with a durable Diamond-Like Carbon (DLC) coating. Its architecture measures 40 mm in diameter and 11.85 mm in height, providing established wrist presence. The case incorporates a screw-down case back, finished with a satin effect and fitted with a flat sapphire crystal for viewing the internal mechanism. Further enhancing the case's integrity is a polished screw-down bezel, distinguished by side knurling and a full thread design. The overall case finish presents a contrast, utilizing partly polished surfaces alongside vertical satin finishing. An onion-style crown facilitates time-setting and winding operations. Ensuring compatibility with standard strap options, the lug width is specified at 20 mm. Water resistance is rated at 3 bar, equivalent to a depth of 30 meters, rendering the watch suitable for incidental water exposure but not for swimming or diving activities.

Powering this timepiece is the automatic Caliber C. 283 movement, composed of 28 individual parts and operating at a frequency of 4 Hz, or 28,800 alternations per hour (A/h). This high frequency contributes to the smooth sweep of the seconds hand and overall timekeeping precision. The movement provides an approximate power reserve of 42 hours when fully wound. Its internal construction includes 28 jewels, minimizing friction at critical points. Aesthetic finishing of the movement components includes nickel-plating and circular-graining on the bridges, accented with spiral offsets. The rotor, visible through the case back, is rhodium-plated, skeletonised to reduce mass, engraved, and features Geneva Stripes decoration, mounted on efficient ball bearings. The display configuration is notable, presenting digital jumping hours via an aperture positioned at 12 o'clock, complemented by an off-centre minutes subdial and a small seconds indicator located at 6 o'clock. The hands are "Feuille" shaped, rhodium-plated and diamond-cut, or alternatively lacquered, with the minute hand specifically curved by hand to accommodate the dial's topography.
