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. “The UR-105 TA is our URWERK Knight,” says Martin Frei, artistic director and co-founder of URWERK. “The bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time. The UR-105 TA is an haute horlogerie creation, with all high-end codes respected, but in the Black Orange or Black Lemon versions, it’s their zesty appeal that really arouses the senses.” Sand blasting and micro bead blasting are applied with the same care as with more classical timepieces. However, the addition of bright colors has these watches bursting into life, and infusing them with real energy. It is the watch that the team had the most fun in designing, the most pleasure in developing its mechanisms, and the most satisfaction in its hand finishing and assembly.
