It sparkles brightly in the spotlight. The UR-100V Stardust is bound to ignite a radiant twinkle in your eyes – a true watchmaker’s promise. This UR-100V will tell you tales of stars and distant constellations, nascent beauty and flamboyance, flashes of lightning and transparent reflections. It is set with 400 diamonds (VVS1, Color D) totaling almost 1.90 carats of pure carbon. The technique chosen here is that of snow-setting.

Four hundred diamonds meticulously selected from eight different formats adorn the case of the UR-100V Stardust. Only the edges of the watch have been left bare. Run your finger over this mosaic of diamonds and you’ll find the structure is soft to the touch, smooth, and fluid. Making this setting was however quite a challenge, because of the nature of the steel used here. Harder and less malleable than gold, steel required more complex and meticulous jewelry craftsmanship. Beneath the UR-100V Stardust's crystal globe, the minutes scale – located on the upper part of the railway-type track – is studded with 36 diamonds, while another 24 adorn the watch crown. The steel pin buckle is enhanced by two rows comprising 11 diamonds each.

In addition to its aesthetics and its wandering hour movement, the UR-100V Stardust is spatial by nature. Like all watches in the 100 collection, it features two recesses on the flanks of its satellite carrier. The first is a kilometer counter representing the distance traveled by the Earth on its own axis in 20 minutes (i.e. 555 km). The second is another kilometer counter showing the distance traveled by the Earth around the Sun during the same period (i.e. 35,740 km). In this way, the UR-100V Stardust bears witness to the Earth's journey across the void of space, passing millions of suns and reflecting their light.
