• UR-105TA

The UR-105 TA revisits URWERK's iconic satellite indication, which has been an emblematic and instantly recognizable signature element of the brand for 18 years.
The “TA” of the UR-105 TA stands for “Turbine Automatic”. That is because the movement’s automatic winding is optimally regulated by dual air turbines on full show on the back.

“The UR-105 TA is our URWERK Knight; the bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time.
