Quick TakeStep into the shadows with the Night Prowler, a watch that's less about telling time and more about celebrating the intricate dance of mechanics after dark. Its DLC-coated stainless steel case is like a piece of captured midnight, sleek and commanding on the wrist at 44mm. But the real show happens beneath the sapphire crystal. Forget a simple dial; this is horological theater on multiple levels! You've got the skeletonized base revealing the meticulously finished C.677S manual-wind movement – check out those blued screws and circular graining! Then there's that pop of red bearing the unique limitation number, reminding you this isn't just any watch, it's one of only thirty. The galvanic black top layer anchors the signature Chronoswiss regulator display: hours up top, seconds down low, and that big central minute hand sweeping with purpose. It's a functional layout born from precision, now reimagined as pure mechanical art. The hand-bent "Poire Stuart" hands add a touch of classical elegance to this otherwise modern marvel. Strapped on with hand-sewn Louisiana alligator leather, it’s a statement piece that truly comes alive when the lights go down.

DescriptionThis timepiece, reference CH-6725S-BKBL, utilizes the manually wound Caliber C.677S movement, composed of 21 individual parts. Its operational frequency is specified at 2.5 Hz, equivalent to 18,000 alternations per hour (A/H). Incorporating 17 jewels to minimize friction at critical points, the mechanism provides an approximate power reserve of 46 hours when fully wound. The movement's architecture is extensively revealed through skeletonization of the plates and bridges, which are further enhanced with circular graining. Finishing details include polished surfaces on the pallet, pallet-wheel, and screws. The gear wheels are also skeletonized, adding to the visual depth and complexity. A notable aesthetic refinement is the thermal bluing applied to the screws, providing a distinct contrast against the metallic components. This intricate mechanical assembly is visible through both the dial aperture and the exhibition case back. The regulator display separates time indications: hours are shown off-center at the 12 o'clock position, central minutes dominate the main dial axis, and small seconds are displayed on a subdial at 6 o'clock. This arrangement prioritizes the minute display, historically significant for precision time-setting.

The watch is housed within a robust case constructed from stainless steel treated with a Diamond-Like Carbon (DLC) coating for enhanced durability and a dark aesthetic. Dimensional specifications include a case diameter of 44 millimeters and a height of 12.48 millimeters, establishing a significant wrist presence. The lug width measures 22 millimeters, accommodating the supplied strap. Case finishing is meticulously executed, featuring a combination of partly polished and partly vertically satin-finished surfaces. A distinctive onion-style crown facilitates winding and time-setting functions. The bezel is a polished, screw-down type, characterized by a full thread design and side knurling for improved grip, securing a curved, non-reflecting sapphire crystal that protects the dial. The case back is also a screw-down design, featuring a satin finish and an integrated sapphire crystal window for viewing the movement. Water resistance is rated at 3 bar, equivalent to approximately 30 meters, offering protection against incidental water contact. The dial itself exhibits a sophisticated multi-level construction. Its foundation is a skeletonized base incorporating a funnel structure. A distinctive middle level, rendered in red, displays the individual limitation number, signifying its exclusivity as one of only 30 pieces produced worldwide. The top level is galvanic black and is screwed onto foundation blocks, completing the complex visual hierarchy. Time indication is achieved via lacquered and curved hands in the "Poire Stuart" shape; the minute hand is meticulously bent by hand to follow the dial's curvature.
