The UR-105TA RG

First launched in 2015 limited to just 100 pieces, the RG is the crown jewel of the 105 series. The UR-105 TA is a real watchmaker's watch that explodes with creativity. It isn't round, has no hands, and no tourbillon: It is 100% pure URWERK.

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. These turbines are bead- blasted, satin-finished and treated with black PVD for perfect aesthetics. The winding mode is selected by a small lever. In the “FULL” position, only the slightest movement is needed to wind up the mainspring. "RED." (for “REDUCED”) moderates the winding so as to minimize excessive tension on the mainspring. On "STOP" mode, the winding system is disabled and the UR-105 TA can then be hand-wound if necessary by the crown.
