URWERK UR-100V LS Ceramic “LightSpeed”

Time, measured by distance.

The UR-100V LS Ceramic “LightSpeed” rethinks timekeeping by translating the speed of light into a mechanical experience. Using URWERK’s signature wandering hour satellite, the watch shifts roles mid-cycle—moving from minutes to mapping the journey of a photon travelling from the Sun to the planets.

This is not metaphor. Each indication corresponds to real astronomical data, turning the dial into a cosmic interface where time is no longer counted, but travelled.

The white ceramic composite case is as radical as the display itself. Developed in-house by URWERK, it combines ceramic fibres, glass fibre, and carbon within a polymer matrix—retaining the visual purity of ceramic while dramatically improving shock resistance. The result is a case that feels engineered, not ornamental.

Powered by the automatic calibre UR-12.02 and regulated by URWERK’s Windfänger system, the UR-100V LS Ceramic balances conceptual ambition with mechanical control. A watch that doesn’t explain the universe—just reminds you how vast it is.
