The URWERK UR105-CC revisits URWERK’s iconic satellite indication, which has been an emblematic and instantly recognisable 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 carrousel is a critical component and is made from ARCAP, which has been treated with ruthenium then micro-bead blasted to a finish meeting the very highest standards of fine watchmaking.
Four satellites, each carrying three hour numerals, successively reveal themselves as they parade past the minute rail to display the time.The movement’s automatic winding is optimally regulated by dual air turbines on full show on the back.
The winding mode is adjusted via the small lever above the turbines.
In the “FULL” position, only the slightest movement is needed to wind up the mainspring.
“RED.” (for “REDUCED”) moderates the winding so as to minimise 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.
At the heart of UR-105 time display four forged-aluminium satellites slowly orbit. Each of these satellites is visible during their 60-minute journey along the minute scale.
The two turbines visible on the back are coupled to the rotor to regulate the winding system of the watch. These micro-rotors are bead-blasted, satin-finished and treated with black PVD for perfect aesthetics.
Few watches have managed to captivate the imagination and wonder like the UR105. Only 15 fortunate owners of the URWERK UR105-CC exist. The UR105-CC was delivered at the castle of Arteaga in the north of Spain. Event…
