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.
“The UR-105 is our URWERK Knight; the bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time."
HOUR SATELLITE INDICATION AND TURBINE AUTOMATIC
Four satellites, each carrying three hour numerals, successively reveal themselves as they parade past the minute rail to display the time.
