Urwerk UR-105 TA "Clockwork Orange"
It takes a long time to develop a mechanical watch like the UR-105TA — three years of research before even starting. But how long does it take to build such a mechanism? We can’t give you an exact figure, but we do know that to make and finish each of its parts needs hours of relentless work and concentration at the workbench.
Creators: Felix Baumgartner and Martin Frei
Engineers: Dominique Buser and Cyrano Devanthey
CNC machine tool operators: Martin Schiess and Roland Hohl
Assembly and technical finishing: Hervé Morard, Raphael Doddi and Vera Moita
We invite you to share key moments in the creation of the UR-105 TA Clockwork Orange.
- Fashioning and finishing: all the parts for the indications are made in Urwerk's premises and decorated by hand.
- Adjusting the hours carousel and watch assembly
The UR-105 TA embodies all the years of research invested into URWERK’s wandering hour satellites. Here, the ingenuity of the mechanism lies in the invisible carousel responsible for the operation of the satellite hours. The hidden carousel has been treated with ruthenium then bead blasted to a finish meeting the very highest standards of haute horlogerie.
Four satellites made of aluminum and mounted on their own bronze/beryllium Geneva cross - all precisely cut on URWERK’s CNC machine tools - slowly orbit to display time.
Each satellite completes four 120° turns in the period between leaving the minutes arc and arriving again, displaying a new numeral.
A circular canopy with openings highlights the current hour. Once the hour has elapsed, the satellite – guided by a Geneva cross – rotates as it continues its orbit for another three hours before returning to center stage.
The UR-105 TA Clockwork Orange features dual air turbines on full show on the back through two sapphire glasses in an impressive titanium body. These turbines are coupled with the rotor and adjust the speed of the winding system to minimise wear.
Creating the Clockwork Orange is like turning an organic entity, full of juice and sweetness, into a machine.
