Quick TakeForget subtle hints of mechanics; the SkelTec Black throws the engine bay wide open for all to see. This isn't just a watch; it's a kinetic sculpture strapped to your wrist. The stark contrast between the deep black DLC steel and the warm glow of 18-karat red gold isn't just visual flair; it's a statement about duality – strength meets luxury, modern tech meets classic metal. Gazing through the skeletonized dial is like peering into a miniature, meticulously organized industrial landscape. You see the balance wheel oscillating frantically at 28,800 A/h, the lifeblood pulse of the machine. The open spring barrel subtly reminds you of the 48-hour power coiled within, energy waiting to be unleashed through the intricate gear train. Even the hands are stripped down, letting the mechanics shine through. It takes guts to wear something this exposed, this technically complex. It's a conversation starter that bypasses small talk and dives straight into the deep end of horological appreciation, all wrapped in a form inspired by fluidity and organic shapes, despite its sharp, modern execution.

DescriptionThe SkelTec reference CH-3715R-BK incorporates a complex case architecture composed of 51 individual parts. Its primary material is stainless steel treated with a Diamond-Like Carbon (DLC) coating, selected for its high hardness and scratch resistance, providing a durable, dark aesthetic. Enhancing this foundation, specific components including the bezel, the crown, the fastening screws, and the case back retaining ring are fabricated from solid 18-karat red gold, introducing a contrasting element of precious metal. Dimensionally, the case presents a substantial diameter of 45 millimeters and a height profile of 15.15 millimeters, establishing a significant wrist presence. The overall finish applied to the case surfaces is a sand-blasted matt texture, minimizing reflectivity and contributing to its technical appearance. Water resistance is rated at 5 bar, equivalent to approximately 50 meters, offering protection against incidental water exposure but not intended for prolonged immersion or aquatic activities. The strap interface is standardized at a 22-millimeter band width, allowing for strap interchangeability. Securing the case back is a screw-down system, ensuring integrity against dust and moisture ingress; this back features a satin finish and incorporates an aperture fitted with sapphire crystal, permitting observation of the movement within. The front aperture is protected by a curved sapphire crystal, treated with a double anti-reflective coating to maximize legibility by reducing glare from ambient light sources. The bezel exhibits both polished and knurled textures, adding tactile and visual complexity.

Powering the timekeeping functions is the Manufacture caliber C.304, a manually wound mechanical movement developed in-house. This movement operates at a frequency of 4 Hz, which translates to 28,800 alternations per hour (A/h), a rate conducive to stable timekeeping accuracy. It incorporates 21 jewels, synthetic rubies strategically placed at high-friction points within the gear train and escapement to minimize wear and optimize energy transmission. When fully wound, the caliber C.304 provides a power reserve of approximately 48 hours. A defining characteristic of this movement is its extensive skeletonization, a process involving the removal of non-essential material from plates and bridges to reveal the intricate workings beneath. Key components highlighted by this open-working include the balance wheel, the regulating organ of the watch, and the mainspring barrel, which houses the power source. The dial itself is also skeletonized, featuring a galvanic black coloration and a matt finish that complements the case treatment. Time indication is restricted to central hours and minutes, displayed via skeletonized hands. These hands are plated in red gold to harmonize with the case accents and feature Super-LumiNova inlays, providing luminescence for readability in low-light conditions. The included strap combines calf skin with textile elements, fastened by a folding clasp mechanism for secure and convenient wear.
