With its manually wound movement and control board on its back, the UR-220 goes back to URWERK’s earlier technologies in a case that is sleeker, more ergonomic and as stunning as ever. One exceptional feature is the return of the Oil Change indicator in a new guise. he UR-220 features a high-tech, oversized, three-dimensional retrograde minute hand. It encloses the hour satellite and indicates the time as it transverses the 0-to-60-minute scale. Then in less than 0.1 of a second the hand flies back to dock with the next hour satellite.
The 48-hour power reserve is indicated in the upper left and right corners, featuring two hands moving across two scales. This power reserve distributed on two sub-dials is made up of 83 components, testifying its complexity of development. The oil change indicator keeps a running track of how long (in months) the movement has been in operation. The ultra-light case is made of 81 layers of CTP Carbon, compressed in a resin. These extremely thin layers (thickness : 0.15mm) are made to resist the onslaught of time. The carbon structure draw on the UR-220 a refined frame which underline the profiled shape of the case.
