A Stellar Finale: The UR-230 Black Star - Pioneering Horological Craftsmanship

The Evolution of a Lineage: Concluding the 230 Series

The UR-230 series, initiated in 2023, has reached its exciting conclusion with the introduction of the Black Star edition. This series builds upon the foundation of the revered 200 collection, which previously featured the enduring UR-210 and the concise UR-220. While retaining the distinctive satellite time display that has captivated enthusiasts since 2006, the UR-230 models have incorporated advanced features such as a dual-variable geometry turbine and an innovative hybrid winding mechanism. Following the initial UR-230 Eagle and the striking white ceramic UR-230 Polaris, the Black Star now completes the collection with a return to classic black and yellow tones, signifying a fitting end to this remarkable chapter.

Innovative Design and Material Mastery: The Aerodynamic Case

The UR-230 Black Star proudly showcases the series' recognizable aerodynamic case, a hallmark of its design philosophy. The journey began with the Eagle, featuring a black DLC-coated titanium and Carbon Thin-Ply composite structure, complete with a protective mobile cover—a classic Urwerk touch. The Polaris then ventured into a bright, layered ceramic composite. The Black Star, while appearing stylistically familiar, introduces a unique material composition: a hermetic titanium core providing 30-meter water resistance, encased within a specially developed laminated ceramic composite shell. This shell combines layers of braided ceramic, fiberglass, and carbon fiber within a polymer matrix, revealing a shimmering, textured surface upon machining. The case maintains its substantial dimensions, measuring 44.81mm in width and 53.55mm in length.

A Spectacle of Time: The Distinctive Dial Configuration

The face of the UR-230 Black Star features the same intricate and original display that defines the 230 collection, evolving from its predecessors. This complex mechanism includes a satellite complication for wandering hours and a three-dimensional retrograde hand, all anchored by a central hub. Three cubic hour satellites rotate, traversing a 120-degree arc over sixty minutes. The currently active hour is guided along the minute track by an open-worked retrograde hand. As the sixty-minute cycle concludes, this hand swiftly resets to zero, ready to engage with the next satellite. The dial's aesthetic is completed with a sophisticated palette of gray and black, accented by vibrant yellow luminescent elements.

Precision Engineering: The Self-Winding Mechanism

Beyond its time-telling functions, the UR-230 Black Star integrates several sophisticated indicators. The watch is powered by a self-winding movement, built on a Vaucher base, which is precisely regulated by an exclusive dual-turbine system. One turbine effectively dampens external shocks, while the other modulates the airflow of the automatic winding system, functioning as an aerodynamic brake. A control located on the watch's reverse side allows for the adjustment or complete deactivation of the rotor's winding, enabling a transition to manual winding. Two symmetrically positioned indicators at 11 and 1 o'clock display these settings. The Calibre UR-7.30 movement offers a robust 50-hour power reserve.

Exclusivity and Future Prospects: The Black Star Edition

The Urwerk UR-230 Black Star is offered with a vibrant yellow vulcanized rubber strap, secured by a Velcro-fastened black DLC-treated buckle. This exceptional timepiece is a limited edition, with only 35 units available, each priced at CHF 150,000 (excluding taxes). As stated by the brand, the Black Star marks the culmination of the 230 collection, closing one chapter while simultaneously foreshadowing new horological adventures in 2026. Enthusiasts are encouraged to anticipate what innovative creations Urwerk will unveil next. More comprehensive details can be found on urwerk.com.
