A watch that makes sunlight take time.

Published 21 October 2026 · WHV · Public-source editorial note

Sunlight feels immediate, yet the light reaching Earth has travelled for roughly eight minutes. URWERK turns that interval into something a watch wearer can contemplate. The UR-100V LightSpeed Ceramic lets a familiar passage of minutes lead into a much less familiar sense of distance.

The hand continues into another scale

Introduced in February 2026, this version combines wandering-hour satellites with a display representing the eight planets and the time sunlight takes to reach them. After leaving the minutes track, a satellite becomes a marker within that astronomical narrative. It is a mechanical translation of scale, not a device detecting individual photons or calculating every planet’s changing distance in real time.

The white case is also more specific than a colour treatment. URWERK describes a developed composite construction involving ceramic, glass and carbon fibres, with a titanium inner case and caseback. That description should not be flattened into an assertion that ordinary ceramic has become unbreakable. The material is part of this particular object’s engineering proposition.

An astronomical idea, not a live ephemeris

Ask to see the display operate before judging it from a still image. Follow the conventional reading first, then the astronomical continuation, and discuss servicing the specialist mechanism. The lasting attraction is an independent maker’s ability to make a cosmic relationship personally legible. A complication can enlarge the meaning of an everyday object without needing to pretend that it is useful in exactly the same way as a stopwatch.
