Quick TakeForget stuffy tradition; the Flying Regulator Open Gear CH-8753-BKBK is where mechanical artistry throws a party right on your wrist. Chronoswiss rips up the rulebook, exposing the beating heart – or at least, its gear train – through that killer multi-level dial. It’s like having a tiny, intricate machine operating out in the open, not hidden away. The regulator layout, separating hours, minutes, and seconds, feels both purposeful and playfully technical. Central minutes sweep boldly, while the hours tuck away neatly up top, and the seconds tick within their own dedicated funnel. The black galvanic base makes the rhodium-plated bridges and red seconds hand pop. You see the C.299 movement's components, the bridges acting as structural elements of the dial itself. It's robust too, with that 100m water resistance and sturdy steel case. Strapped on with that gator leather, it's a conversation starter that says you appreciate precision but don't take things too seriously. It's horology with an edge, a wink, and a view inside.

DescriptionThe Chronoswiss Flying Regulator, reference CH-8753-BKBK, features a stainless steel case construction composed of 16 individual parts. Its dimensions measure 41 mm in diameter and 13.85 mm in height, accommodating a strap width of 21 mm. Case finishing employs a combination of polished and vertically satin-finished surfaces, complemented by a characteristic onion crown. Protection for the dial is provided by a curved, non-reflecting sapphire crystal, secured by a polished screw-down bezel featuring a full thread and side knurling. The case back utilizes a screw-down design with a satin finish and integrates a sapphire crystal for movement observation. Water resistance is rated at 10 bar, equivalent to 100 meters, ensuring robustness for various conditions. The dial architecture is notably complex, built on two distinct levels. A galvanized black bottom level serves as the foundation, while the upper level incorporates screwed-on skeletonized train wheel bridges and distinctive funnel-like structures for the hour and second displays, embodying the "Open Gear" concept where the dial also functions as the module board.

Powering this instrument is the Caliber C.299 automatic movement, operating at a frequency of 4 Hz (28,800 alternations per hour) and providing an approximate power reserve of 42 hours. This intricate mechanism runs on 31 jewels. Movement finishing includes a rhodium-plated pallet with spiral offsets, circular-grained bridges, and the application of either thermally blued or polished screws, signifying meticulous attention to detail. Further enhancing the visual appeal and technical specification is the skeletonized, galvanic black rotor, distinguished by engraved Geneva Stripes and mounted on a ball bearing for efficiency. Special technical features extend to a polished pallet lever, escape wheel, and screws, alongside perlage finishing on bridges and plates. Time indication follows the classic regulator format: off-centre hours are displayed at the 12 o'clock position, central minutes dominate the main dial axis, and small seconds reside at 6 o'clock. The Feuille-shaped hands are rhodium-plated and polished, featuring Super-LumiNova inlays for low-light legibility; the minute hand is uniquely bent by hand, and the seconds hand is painted red for contrast. Completing the ensemble is a hand-sewn Louisiana alligator leather strap secured by a folding clasp.
