The UR‐210: Never has a timepiece displayed such feedback and attachment to its owner. In a first for a wristwatch, URWERK’s UR‐210 highlights and monitors the symbiotic relationship between man and his mechanical watch. While the UR‐210 is characterized by its original URWERK time display, of equal note – and with reason − is the UR‐210’s personalized communication with its owner.
The dial of the UR‐210 features a traditional power reserve indication at one o’clock. In a near mirror image at 11 o’clock we find a similar indication. No, it isn’t a duplicate fail‐safe, but something much more important which deserves our full attention, because it is actually a world‐first complication that indicates winding efficiency over the last two hours.
When you are comfortably nestled in your armchair, the indicator will be tending towards the red zone to tell you that your UR‐210 is not being wound enough by its automatic rotor and is running on stored energy. However, if you are moving around energetically, the indicator will point towards the green zone, a sign that you are replenishing your watch with new energy. This entirely new indication does not measure mainspring torque, but calculates the difference between the consumed and generated energy of the mainspring.
Armed with knowledge of both winding efficiency and available power reserve, you are now able to intervene. If your UR‐210 indicates an insufficient supply of energy, you can position the winding efficiency selector (at the back of the watch) to “FULL”.
The rotor will then convert the slightest movement into stored energy. In this configuration, a turbine connected to the rotor provides smooth, unimpeded power. But if you are more active, then that may provide more power than required and unnecessarily wear the mechanism. In that case, you would position the winding efficiency selector to “REDUCED” to engage the rotor damping system. An air turbine compressor mounted on ruby bearings spins and creates internal resistance – enough friction to slow down or dampen the automatic winding rotor. In “STOP” mode, the automatic winding system is disabled completely and the UR‐210 runs off reserve power and may require manual winding.
