Quick TakeStripping away everything but the essentials, the SkelTec Azur CH-3718-BKBLB lays its mechanical soul bare. This isn't just a watch; it's kinetic sculpture for the wrist, a conversation between industrial might and artistic vision. The deep black of the DLC-coated steel case acts as a perfect void, dramatically framing the intricate network of the skeletonized C.304 hand-wound movement. Forget hidden secrets; here, the open balance wheel performs its hypnotic dance centre stage, while even the spring barrel puts on a show. Then, that electric blue CVD explodes onto the scene – coating the bezel, screws, and dial elements, it’s like a jolt of pure energy against the darkness. It’s bold, unapologetic, with that substantial 45mm diameter making a clear statement. The knurled bezel adds a touch of tactile intrigue, contrasting with the smooth, sand-blasted finish elsewhere. Even the hands, skeletonized and tipped with lume, feel like extensions of the mechanical architecture beneath. Strapping it on feels like harnessing a piece of beautifully controlled chaos, a testament to engineering pushed into the realm of radical design. It’s a watch that doesn’t just tell time, it performs it.

DescriptionThe Chronoswiss SkelTec Azur, reference CH-3718-BKBLB, features a multi-component case construction comprising 51 individual parts. The primary case material is stainless steel, enhanced with a durable Diamond-Like Carbon (DLC) coating for increased scratch resistance and a distinctive dark aesthetic. Specific components, namely the bezel, fastening screws, and the case back retaining ring, receive a contrasting blue Chemical Vapor Deposition (CVD) coating, lending the timepiece its unique Azur designation. The overall case architecture presents an organically inspired shape characterized by skeletonized lugs, reducing visual mass and contributing to the model's avant-garde design philosophy. Dimensional specifications place the case diameter at a substantial 45 millimeters, with a total height measuring 15.15 millimeters. Lug spacing accommodates a strap width of 22 millimeters. Surface treatment throughout the main case body consists of a sand-blasted matt finish, providing a non-reflective, technical appearance that complements the DLC coating. The bezel element exhibits a polished and knurled texture, offering tactile feedback and visual contrast. This bezel, also treated with the blue CVD coating, frames a curved sapphire crystal. Said crystal incorporates a double anti-reflective coating to ensure optimal legibility by minimizing glare from various angles. Securing the case structure is a screw-down case back, fabricated from polished stainless steel and fitted with an integrated sapphire crystal window, allowing observation of the movement within. The timepiece is rated for water resistance up to 5 bar, equivalent to approximately 50 meters, offering protection against incidental water exposure.

Powering the SkelTec Azur is the Manufacture Caliber C.304, a manually wound mechanical movement developed in-house by Chronoswiss. This caliber is specifically engineered with extensive skeletonization, a defining characteristic of the SkelTec collection. Key architectural features include an open balance wheel, prominently displayed for visual appreciation of the oscillating component, and a similarly skeletonized spring barrel, revealing the mainspring. The movement operates at a frequency of 4 Hertz, which translates to 28,800 alternations per hour (A/h), a rate conducive to stable timekeeping performance. Comprising 21 jewels to minimize friction at critical points within the gear train and escapement, the Caliber C.304 provides a power reserve of approximately 48 hours when fully wound. The dial itself adheres to the skeletonized theme, constructed from material finished with a matt texture and treated with the same blue CVD coating found on the external case components, ensuring design cohesion. Time indication is achieved through central hour and minute displays. The hands responsible for this display are also skeletonized to match the overall aesthetic, featuring lacquered surfaces and inlaid sections of Super-LumiNova for enhanced visibility in low-light conditions. Completing the watch is a strap combining calf skin leather with a textile element, attached to the wrist via a folding clasp mechanism for secure and convenient fastening. The combination of advanced materials like DLC and CVD coatings, intricate skeletonization of both case and movement, and the hand-wound Manufacture Caliber C.304 positions the SkelTec Azur as a highly technical and visually distinct offering within the Chronoswiss portfolio.
