The UR-110 is a watch with attitude. From the base of its unusual asymmetrical case to the three arrow-shaped "torpedoes" flying in formation with the mission of indicating the time, the UR-110 has serious attitude. Enveloped in a secure titanium case, planetary gearing keeps the three hour satellites in parallel formation as they take turns to indicate the time as they pass the 60-minute track. An "Oil Change" indicator alerts the user when it is time for a service; a “Day/Night” indicator helps keep track of changing time zones; and twin turbines on the back minimize wear in the automatic winding system.
