Urwerk UR-105 TA uses the new caliber UR 5.02 – which has 48 hours of power reserve and operates at 4Hz (28,800 bph). From the “dial” of the watches, it could be easy to confuse the two models, but there are changes here as well as internally, and the movements offer rather different displays. The dial is covered with a custom-shaped sapphire crystal and you only have the time with hours and minutes using a version of Urwerk’s popular “satellite” time display, which has turning discs with hour markers on them that drag across an arched minute scale. It is a very different way of telling the time as compared to standard hands, but ends up being remarkably easy once you get the hang of it.
When you flip the watch over, you will notice the set of turbines that visually spin with the rotor, as well as a lever to stop the rotor for when you expect "serious movement" and potential shock) making it the ultimate sports watch.
