Quick TakeForget subtle elegance; this Chronoswiss Flying Regulator in red gold is a declaration. The CH-8751R-SISI isn't just showing you the time; it's putting the entire intricate dance of gears on full display with its "Open Gear" face. That multi-level dial isn't merely functional; it's architectural, with bridges and funnels drawing your eye right into the mechanical heart beating at a brisk 28,800 A/h. You see the silver base, the golden gleam of the bridges holding the exposed wheels, the off-center hour dial leaving pride of place for that long, central minute hand. Even the seconds subdial gets its own stage. It's a confident piece, blending the warmth of 18k red gold with the cool mechanics laid bare. The hand-bent minute hand and that pop of red on the seconds add just the right amount of flair. Strapped on with that hand-sewn alligator leather, it feels substantial, technical, yet undeniably luxurious – a conversation starter that happens to tell time with regulator precision.

DescriptionThe Chronoswiss Flying Regulator, reference CH-8751R-SISI, features a case constructed from 18 karat red gold, comprising 16 individual parts. Its dimensional specifications include a diameter of 41 millimeters and a height of 13.85 millimeters, providing substantial wrist presence. The case incorporates a screw-down back crafted with a satin finish, integrating a sapphire crystal for viewing the internal mechanism. The case finish is executed with a combination of polished surfaces and areas featuring a vertical satin finish, contributing to its complex visual texture. An onion-style crown facilitates winding and time-setting operations. Protecting the dial is a polished screw-down bezel, distinguished by a full thread and side knurling, which secures a curved, non-reflecting sapphire crystal. The lug width, determining strap compatibility, measures 21 millimeters. This construction ensures water resistance rated to 10 bar, equivalent to a depth of 100 meters, suitable for surface water activities but not deep diving. The integration of the screw-down case back and bezel enhances the structural integrity and protective qualities of the enclosure against environmental factors such as dust and moisture ingress. The choice of 18k red gold underscores the luxurious positioning of this timepiece, while the specific finishing techniques applied demonstrate meticulous attention to detail in its manufacturing process, blending robustness with refined aesthetics suitable for a high-caliber mechanical watch.

Powering the CH-8751R-SISI is the Chronoswiss Caliber C.299, an automatic movement operating at a frequency of 4 Hz, which corresponds to 28,800 alternations per hour (A/h). This frequency contributes to the smooth sweep of the seconds hand and overall timekeeping precision. The movement provides a power reserve of approximately 42 hours when fully wound, allowing for nearly two days of autonomous operation off the wrist. It is built incorporating 31 jewels to minimize friction at critical points within the gear train and escapement, enhancing longevity and efficiency. The movement's finish includes a rhodium-plated pallet featuring spiral offsets and circular-grained bridges, showcasing traditional horological decoration techniques. Fasteners within the movement are either thermally blued or polished screws, adding further visual refinement. A key feature visible through the case back is the skeletonized rotor, which is red gold plated and meticulously engraved with Geneva Stripes (Côtes de Genève), a hallmark of fine watchmaking; it is mounted on ball bearings for efficient winding. Additional special finishing elements include a polished pallet lever, escape wheel, and screws, alongside perlage (circular graining) applied to bridges and plates. The dial itself presents an elaborate multi-level construction. The base level is finished with a galvanized silver appearance. Layered above this is the upper level, featuring screwed-on skeletonized train wheel bridges and distinct funnel-like structures framing the hours and seconds displays, central to the "Open Gear" concept. Time is indicated via off-centre hours positioned at 12:00, central minutes, and a small seconds display located at 6:00, characteristic of a regulator layout. The "Feuille" shaped hands are red gold plated and polished, featuring Super-LumiNova inlays for low-light visibility; the minute hand is manually bent to follow the dial curvature, and the seconds hand is distinctively painted red.
