UR-101 | Yellow Gold size-20-x-16 tantalum is highly resistant toThis is one of the first examples of the UR 101, an experimental idea that became Urwerk. Inspired by the Millennium Falcon from the Star Wars franchise, it features a 38 solid gold case crafted by hand. Its minimal wandering hours time display, underpinned by a module featuring a Maltese cross, takes inspiration from a 17th century papal night clock. Produced in exceedingly small numbers, the UR 101 is as rare as it is consequential to Urwerks story.
