Quick TakeForget subtle – the Chronoswiss Open Gear Flying Tourbillon Sunset is a vibrant explosion of mechanical artistry strapped to your wrist. It’s like the engineers captured the fiery hues of dusk, infused them into metal and glass, and then let the gears run wild. The stunning blue CVD-coated movement parts peek through the intricate, multi-layered dial, clashing beautifully with the warm, sunset-orange guilloche pattern. You can literally see the heart beating with the mesmerizing dance of the flying tourbillon at 6 o'clock, completely unobstructed. The unique off-center hour display in its funnel adds a quirky, technical edge, reminding you this isn't just pretty; it's seriously clever watchmaking. Those skeletonized bridges and the visible gear train (the 'Open Gear' magic) make it feel alive. Strapped on with that Cordura or optional alligator, it feels substantial, purposeful, a wearable piece of kinetic sculpture limited to only a handful of wrists worldwide. It’s less a time-teller, more a conversation piece that screams confidence and a love for intricate mechanics.

DescriptionThe Chronoswiss Open Gear Flying Tourbillon Sunset, reference CH-3123-ORBL, presents a meticulously engineered housing constructed from stainless steel. This case assembly comprises 17 distinct components, culminating in a structure with a diameter measuring 44 millimeters and a height of 13.35 millimeters. Adhering to robust design principles, the case back utilizes a screw-down mechanism, featuring a satin finish complemented by an integrated sapphire crystal for movement observation. The overall case finish incorporates both polished and vertically brushed satin surfaces, creating textural contrast. An onion-style crown facilitates winding and time-setting operations. Protecting the complex dial arrangement is a polished, screw-down bezel, distinguished by its full-thread construction and side knurling for enhanced grip. This bezel secures a curved sapphire crystal, treated with a double anti-reflective coating to minimize glare and maximize legibility under various lighting conditions. The lug width, determining strap compatibility, is specified at 22 millimeters. Ensuring practicality for daily wear, the case architecture provides water resistance rated to 10 bar, equivalent to a depth of 100 meters, suitable for surface water activities. The standard strap configuration utilizes a textile Cordura material, known for its durability, although hand-sewn alligator leather is offered as an alternative. Securement to the wrist is accomplished via a stainless steel folding clasp mechanism, offering both security and ease of use. This model represents a highly exclusive offering, limited to a production run of only 15 individual timepieces globally.

Internally, the CH-3123-ORBL is powered by the Chronoswiss manufacture caliber C.303. This movement is a hand-wound mechanism featuring a prominent flying tourbillon complication positioned at the 6 o'clock location. The caliber operates at a frequency of 4 Hz, which translates to 28,800 alternations per hour (A/h), contributing to its timekeeping stability. When fully wound, the movement provides a power reserve of approximately 60 hours. Its architecture incorporates 23 jewels to minimize friction at critical points within the gear train and escapement. The movement is semi-skeletonized, revealing aspects of its inner workings, and features an exclusive aesthetic treatment involving a blue Chemical Vapor Deposition (CVD) coating. Further finishing details include Côtes de Genève decoration on the main plate, circular satin finishing applied to the skeletonized bridges, a balance wheel treated with galvanic anthracite for a distinct appearance, a visibly skeletonized spring barrel showcasing the mainspring, and polished screws throughout the assembly. The dial itself is an exceptionally intricate 42-part construction arranged across multiple levels. The base level exhibits Côtes de Genève decoration. Above this sits the middle level, which is both hand-guilloched and hand-engraved, bearing the inscription “Atelier Lucerne” on its reverse side. The uppermost level showcases screwed-on, skeletonized train wheel bridges and incorporates a unique funnel-like structure dedicated to the hour display. Time indication employs bar or cylinder-shaped indexes treated with Super-LumiNova for low-light visibility. Functionally, the watch displays off-center hours within the funnel structure at 12 o'clock, centrally mounted minutes, and the constantly rotating flying tourbillon cage at 6 o'clock. The hands are executed in the “Trigono” shape, either thermally blued and polished or lacquered, and feature Super-LumiNova inlays and tips for enhanced legibility. This sophisticated dial architecture, combined with the flying tourbillon and "open gear" mechanism visibility, defines the watch's technical character.
