Quick TakeForget subtle elegance; the Chronoswiss Flying Grand Regulator Skeleton is a mechanical spectacle, a bold statement strapped right to your wrist. It’s like peering into the intricate soul of time itself. The multi-layered dial isn't just telling time; it's putting on a show, with gears turning and levers pivoting right before your eyes. That skeletonized C.677S movement, stripped bare, is pure mechanical art – forget a simple case back window, this is a full frontal view! The regulator layout, separating hours, minutes, and seconds, gives it that cool, slightly technical vibe, a nod to old-school precision instruments but with a totally modern, almost industrial feel thanks to the openwork. Those thermally blued Poire Stuart hands sweep across the complex architecture, a flash of color against the metallic landscape. Secured by a rugged Hornback alligator strap, this isn't just a watch; it's a conversation starter, a limited-edition piece (one of only 30!) for someone who appreciates the beauty in complexity and isn't afraid to show off the engine room. It's horological theatre for the modern connoisseur.

DescriptionThis timepiece, reference CH-6723S-SISI, features a case constructed from stainless steel, comprising 21 individual parts. The case diameter measures 44 mm, with a height profile of 12.48 mm. Attachment points for the strap are configured with a width of 22 mm. The case incorporates a screw-down case back fabricated with a satin finish and includes an integrated sapphire crystal for movement observation. Further construction details include a polished, screw-down bezel characterized by a full thread design and side knurling. Protecting the dial is a curved, non-reflecting sapphire crystal. The overall case finish exhibits a combination of partly polished and partly vertically satin-finished surfaces, complemented by a distinctive onion-style crown. Water resistance is rated at 3 bar, equivalent to a depth of 30 meters, providing protection against incidental water contact but not suitable for submersion or swimming.

Powering the watch is the manually wound Caliber C.677S movement, operating at a frequency of 2.5 Hz, or 18,000 alternations per hour (A/H). This movement contains 17 jewels and provides a power reserve of approximately 46 hours when fully wound. The finishing applied to the movement components is extensive: the pallet, pallet-wheel, and screws are polished. Furthermore, the plate and bridges undergo skeletonization and feature circular graining. The gear wheels are also skeletonized, and the screws receive thermal bluing treatment. The time indication follows a regulator format, with off-centre hours displayed at the 12 o'clock position, central minutes, and a small seconds sub-dial located at 6 o'clock. The dial itself represents a sophisticated, multi-level construction. Its base is skeletonized with a galvanic white finish and incorporates a funnel structure; the hour scale uses white varnish. A middle level, also galvanic white, displays the hand-painted individual limitation number. The top level, again galvanic white, is affixed using screwed foundation blocks. Thermally blued "Poire Stuart" hands indicate the time; they possess a distinct curvature, with the minute hand being bent manually. The limitation is restricted to 30 pieces worldwide.
