Urwerk Lightspeed Ceramic Watch
Urwerk's UR-100V Lightspeed Ceramic tracks the time it takes sunlight to reach each planet in the solar system, from Mercury at 3.2 minutes to Neptune at 4.1 hours. A blue and green planetary indicator attached to the carousel arms completes a full rotation in three hours, marking each celestial body as it passes through the openworked center dome. Time displays via Urwerk's signature wandering hour satellites with three revolving indicators and a red arrow sweeping a 120-degree minute track. The 43mm case represents a material breakthrough with proprietary white ceramic reinforced by silver fiberglass and carbon for enhanced shock resistance. Beneath the DLC-treated titanium caseback sits the automatic UR 12.02 caliber running at 28,800 vph with Urwerk's Windfänger turbine system. A mechanical reminder that the light illuminating your dial started its journey from the Sun eight minutes ago.
