With the UR-230 Black Star, URWERK brings its 230 chapter to a close in the most enigmatic way possible. This is not simply a timepiece - it is a study in absence, a wrist-bound vanishing act. The case arrives in a newly developed composite ceramic, its surface scattered with microscopic reflections that evoke the endless depth of interstellar space: vast darkness punctuated by distant light. Beneath that shell, a titanium strongbox guards the UR-7.30 caliber with an almost illicit sense of protection, powering the house's iconic satellite complication and skeletonized retrograde minutes hand. Here, time does not merely pass - it revolves, resets, and resurfaces. An integrated air brake mechanism within the winding system offers something increasingly rare in haute horlogerie: agency over the tactile character of mechanical motion. Finished with a striking green vulcanized rubber strap and limited to just 35 examples, the Black Star arrives as a quiet manifesto on the trajectory of experimental watchmaking - one that moves decisively away from heritage reverence and toward cinematic, material-led encounters. It is less a reference to collect than a narrative to inhabit.
