URWERK UR-105 (PRE-ORDER)

The UR-105 revisits URWERK's iconic satellite indication, which has been an emblematic and instantly recognizable signature element of the brand for 18 years. It is a wandering hour indication based on a carousel which carries the four satellites, each bearing three numerals for the hours. The hours successively sweep past the minutes scale for an analogue and digital display of the time.
