Quick TakeForget hiding the magic; the Chronoswiss Flying Regulator Open Gear CH-8753-SISI puts the mechanical heart right on stage! This isn't just a watch; it's kinetic sculpture for your wrist. The multi-level dial acts like a viewing gallery, with those cool skeletonized bridges holding the gears aloft over the galvanized silver base. It’s pure mechanical theatre, especially with the off-center hours perched at 12 and the small seconds doing their own dance down at 6, leaving the big central stage clear for the commanding sweep of the minute hand. Those thermally blued 'Feuille' hands, glowing subtly thanks to Super-LumiNova, add a perfect pop of color against the metallic backdrop. Inside, the robust Caliber C.299 automatic keeps the show running smoothly at a brisk 28,800 A/h, visible also through the back thanks to the sapphire crystal. You get a solid 100m water resistance and that comfy, hand-sewn alligator strap, making it as practical as it is visually captivating. It's a celebration of gears and precision, designed for someone who appreciates seeing exactly how time is told.

DescriptionThe Chronoswiss Flying Regulator Open Gear, reference CH-8753-SISI, utilizes a case constructed from stainless steel, comprising 16 distinct components. Its dimensional specifications measure 41 mm in diameter and 13.85 mm in height, accommodating a strap width of 21 mm. The case exhibits a combination of finishes, featuring partly polished surfaces juxtaposed with areas of vertical satin finish. A prominent onion-style crown facilitates winding and time-setting functions. Securing the case is a screw-down case back, notable for its satin finish and an integrated sapphire crystal window, allowing observation of the internal mechanism. Complementing the case back is a polished screw-down bezel, characterized by a full thread design and side knurling for enhanced grip. Protecting the dial is a curved sapphire crystal engineered with non-reflective properties to ensure optimal legibility under various lighting conditions. This construction methodology contributes to the timepiece's water resistance rating of 10 bar, equivalent to a depth of 100 meters, safeguarding the movement against moisture ingress during typical aquatic activities excluding deep diving. The architecture emphasizes durability and functional aesthetics, ensuring component integrity while providing visual access to the movement through the exhibition case back. The specific combination of polished and satin finishes enhances the visual depth and complexity of the case design, adhering to established horological standards for case manufacturing and sealing.

Powering the CH-8753-SISI is the Chronoswiss Caliber C.299 automatic movement, a self-winding mechanism operating at a frequency of 4 Hz, corresponding to 28,800 alternations per hour (A/h). This frequency ensures a smooth sweep of the central minute hand and contributes to the movement's timekeeping accuracy. The mechanism integrates 31 jewels to minimize friction at critical points within the gear train and escapement, enhancing longevity and operational efficiency. When fully wound, the C.299 provides a power reserve of approximately 42 hours. Aesthetic and technical refinement is evident in the movement's finish, which includes a rhodium-plated pallet featuring spiral offsets and bridges adorned with circular graining (perlage). Fasteners within the movement are either thermally blued or polished, representing meticulous attention to detail. Further enhancing the visual appeal and technical specification is the skeletonized rotor, which is also rhodium plated and engraved with traditional Geneva Stripes; its rotation is facilitated by a ball bearing mounting system for efficiency. Additional finishing details encompass a polished pallet lever, escape wheel, and screws, alongside plates decorated with perlage. The time indication follows a regulator format: off-centre hours are displayed via a subdial positioned at 12:00, minutes are indicated centrally, and small seconds are shown on a subdial at 6:00. The dial itself presents an elaborate two-level construction; the bottom level features a galvanized silver finish, while the upper level incorporates screwed-on skeletonized train wheel bridges and distinct funnel-like structures surrounding the hour and second displays. The "Feuille" shaped hands are thermally blued and incorporate Super-LumiNova inlays for low-light visibility; the minute hand undergoes a hand-bending process. The timepiece is secured to the wrist via a hand-sewn Louisiana alligator leather strap equipped with a stainless steel folding clasp.
