100V Lightspeed Ceramic, Poetic Time Measurement at the Speed of Light

Urwerk has released the UR-100V Lightspeed Ceramic, a luxury watch featuring a unique composite material of ceramic, glass, and carbon fibers. The timepiece maintains the brand's signature satellite hour display while visualizing the time light takes to travel between planets.
Why it matters
It represents a significant advancement in horological material science, balancing the scratch resistance of ceramic with the impact durability of carbon composites.
The UR-100V Lightspeed Ceramic, like the first UR-100V Lightspeed of 2024 , rather than illustrating the Earth’s movement through space, as earlier SpaceTime models did, visualises something even more fundamental: the time sunlight requires to reach planets of our solar system. It remains unmistakably a UR-100, yet the execution is fresh, and even poetic.
The familiar asymmetrical UR-100 case design remains intact, measuring 43mm wide, 51.7mm long and 14.55mm thick. These numbers suggest a large watch, but the curved profile, integrated rubber strap and crown positioned at 12 o’clock continue to make the UR-100 wear considerably better than expected. It sits naturally on the wrist, avoiding the awkward overhang often associated with unconventional case shapes. This time, however, the exterior is new to the series.
