URWERK UR-203

URWERK UR-203

URWERK released a new version in the 200 collection: the URWERK UR-203. It’s main difference with the rest of the collection, is that its micro-mechanics are now fully visible. The URWERK 203′s case is made of black platinum, a great addition next to the rose & white gold and the AlTiN coated URWERK 202. AITiN was also used for the URWERK 103 Tarantula. However the main difference is it shows the robotic functions of URWERK’s mechanisms to show time.

The telescopic minute hands precisely adjust their length to follow the three vectors marking the minutes: 0 -14; 15 – 44; 45 – 60. Extended, they enable the UR-203 to display the time across a large easy-to-read, dial. Retracted, they allow for a smaller, comfortably sized case providing the wearer with the best of both worlds.

To make a stripped down model distilled to its pure essence, like Martin Frei (URWERK co-founder and designer) wanted, they had to start again at the beginning. Felix Baumgartner, URWERK co-founder and master watchmaker, says they sat down at the drawing board and completely reconsidered the satellite module. “The horological challenge with this complication was to develop a complex mechanism with the minimum of components to ensure its reliability and longevity.

Now the carousel, hour satellites, telescopic minute hands and dial weigh 65% less than the proceeding model (UR-202). The satellite complication now tips the scales at a feather-light 3.57 grams.

The UR-203 is also equipped with URWERK’s double turbine system, the same automatic winding system that is used in the watches of the 200 collection. The turbines are mounted on rubies and are controlled by a three-position lever offering the choice of « FREE », « SPORT » or « STOP ». The position determines the force available from the automatic rotor to wind the mainspring. FREE, where the turbines spin freely; SPORT, where the air pressure generated by the turbines reduces the winding rate by approximately 35%; and STOP, where the turbines and rotor are fully blocked. The speed of the turbines can reach a maximum 16,500 RPM.

The dial shows an «Oil Change» indicator and a 150 year «Horological Odometer». The «Oil Change» indicator informs the wearer when a service is due; an operation recommended every three years of movement operation. Similar to the odometer of a car, the UR-203′s «Horological Odometer» keeps track of the total number of years of operation of the movement.
