Quick TakeForget subtle watches; the Flying Grand Regulator Skeleton is a mechanical exhibitionist that straps pure horological theatre right onto your wrist. It throws convention out the window with that signature regulator layout – hours up top, seconds down low, and the big minute hand sweeping solo across the main stage. But it's the radical skeletonization that steals the show. Chronoswiss didn't just cut away a bit here and there; they carved this thing down to its bare, beautiful bones. You see through it – the bridges, the gears, even the blued screws putting on a performance. That multi-layered dial isn't just for show either; it creates this awesome depth, like peering into a tiny mechanical cityscape, complete with the individually painted limited edition number proudly displayed. Strapped in hand-sewn hornback croc, powered by a hand-wound ticker beating at a classic 18,000 vph, this isn't just a watch; it's a conversation starter, a 44mm declaration of love for gears and springs, limited to only 30 fellow fanatics worldwide.

DescriptionThe case construction of reference CH-6723S-BKLB utilizes stainless steel, comprising 21 individual parts. Its dimensions are specified as 44 millimeters in diameter and 12.48 millimeters in height, providing substantial wrist presence. Attachment points for the strap are configured for a 22 millimeter band width. The case incorporates a combination finish, featuring both polished surfaces and areas with a vertical satin finish, contributing to its visual complexity. A distinctive onion-style crown facilitates winding and time-setting operations. Securing the case is a screw-down back, notable for its satin finish and an integrated sapphire crystal, allowing visual inspection of the movement within. The bezel is a polished, screw-down component, characterized by a full thread and side knurling for enhanced grip and visual detail. Protecting the dial is a curved sapphire crystal treated with an anti-reflective coating to ensure optimal legibility under various lighting conditions. Water resistance is rated at 3 bar, equivalent to approximately 30 meters, offering protection against incidental moisture exposure.

Powering this timepiece is the manually wound Caliber C.677S. This movement operates at a frequency of 2.5 Hz, or 18,000 alternations per hour (A/H), and contains 17 jewels. Fully wound, it provides a power reserve of approximately 46 hours. The movement's architecture is extensively skeletonized, removing material from the plate and bridges to reveal the inner workings. Finishing techniques include circular graining on the skeletonized components, polished pallet, pallet-wheel, and screws, along with thermally blued screws and skeletonized gear wheels. The dial presentation is equally complex, employing a sophisticated multi-level construction. A skeletonized base features a funnel structure, overlaid by a middle level bearing the hand-painted individual limitation number. The uppermost level is galvanic black and affixed to foundation blocks via screws. Time indication follows the regulator format: off-centre hours are displayed at the 12 o'clock position, minutes are indicated centrally, and a small seconds subdial resides at 6 o'clock. The "Poire Stuart" hands are lacquered and curved, with the minute hand specifically noted as being bent by hand.
