Baselworld 2017: Urwerk UR-210 Amadeus
For this retro-futuristic move, the UR-210 was transformed by the expert hands of the talented craftsman, Florian Güllert. Baroque is an apt description of this new creation. “The decoration is very post-Renaissance 17th-century, but on a determinedly contemporary structure,” comments Florian. “The swirling pattern of acanthus leaves is most suitable for this style, contrasting with the angular look of the watch. We have merged the case, the crown protection and the bracelet into one unit to create an exceptional piece. I was given the entire watch to work on and I took it over to produce a design in steel.”
This painstaking work took more than 260 hours to complete. Ensuring the continuity of the design was the main objective and the greatest difficulty for the engraver. “It’s a work of many aspects. The themes must interconnect and complement one another without being superfluous. This is certainly one of the creations of which I am most proud,” concludes Florian.
The UR-210’s satellite complication with retrograde minute is both highly original and totally explosive. The principal feature is a high-tech, oversized, three-dimensional retrograde minute hand. Its function is to enclose the hour satellite and indicate the time as it transverses the 0-to-60-minute scale. This one-hour journey through time, tracing an arc of 120°, is smooth and fluid. But the true nature of the piece is revealed at the end of the 59th minute. Then a sharp distinct “click” signals the return of the minute hand to its starting point. In less than 0.1 of a second the hand flies back to dock with the next hour satellite.
The dial of the UR-210S 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.
Has your recent activity been enough to replenish your UR-210’s energy levels? If yes, the winding efficiency indicator will point emphatically to the green zone. If not, you have been using more energy than you are generating, and the winding efficiency indicator will point to the red zone. Armed with knowledge of both winding efficiency and available power reserve, you are then 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.
