Quick TakeAlright, let's cut through the specs for a second. This Flying Grand Regulator Skeleton isn't just telling time; it's putting on a full mechanical show right there on your wrist. Forget a simple dial – this is a multi-layered stage where Chronoswiss stripped away everything but the essential beauty of the gears and springs. The Caliber C.677S isn't hidden; it is the display, skeletonized to the max, with those cool blued screws popping against the intricate metalwork. The regulator layout splits up the time telling, giving the big minutes hand center stage while hours and seconds get their own spotlights. Wrapped in that tough, dark DLC steel case measuring a confident 44mm, it feels modern and maybe a little rebellious. Then there's the red – not just an accent, but a core part of its personality, shouting from the subdials and minute track. Being one of only 30 makes it more than a watch; it's entry into a very exclusive club. It’s a conversation starter that says you appreciate artistry as much as engineering.

DescriptionThe timepiece designated CH-6725S-REBK utilizes a case constructed from stainless steel enhanced with a Diamond-Like Carbon (DLC) coating, resulting in a durable and aesthetically distinct finish. Dimensional specifications include a diameter of 44 millimeters and a height of 12.48 millimeters, creating a substantial wrist presence. The case assembly involves 21 distinct parts, featuring a screw-down case back executed with a satin finish and incorporating a sapphire crystal for viewing the internal mechanism. Water resistance is rated at 3 bar, equivalent to approximately 30 meters, suitable for incidental exposure to moisture but not for swimming or diving. The case exhibits a dual finishing technique, combining partly polished surfaces with areas featuring a vertical satin finish. A defining characteristic is the traditional onion-style crown. Protecting the intricate dial is a polished screw-down bezel, distinguished by its full thread design and side knurling, fitted with a curved, non-reflecting sapphire crystal. The lug width accommodates a 22 mm strap.

Powering this instrument is the manual winding Chronoswiss Caliber C.677S. This movement operates at a frequency of 2.5 Hz, which translates to 18,000 alternations per hour (A/H). It incorporates 17 jewels to minimize friction at critical points. The fully wound mechanism provides an approximate power reserve of 46 hours. Significant attention has been paid to the movement's finishing; the pallet, pallet-wheel, and screws are polished. Furthermore, the plate and bridges undergo extensive skeletonization and feature circular graining. The gear wheels are also skeletonized, adding to the visual complexity, and are complemented by thermally blued screws. The dial architecture is notably sophisticated, arranged on multiple levels to create visual depth. Both the movement and the dial are intentionally skeletonized, removing material to reveal the underlying mechanics. This model is strictly limited to 30 pieces globally, with the unique limitation number displayed directly on the dial. Attachment to the wrist is achieved via a hand-sewn Hornback crocodile leather strap, secured with a folding clasp mechanism.
