In a first for a wristwatch, Urwerk’s UR-210 highlights and monitors the symbiotic relationship between man and his mechanical watch.
“The UR-210 embodies the symbiotic relationship between man and his watch. This quasi-biologic machine could reveal more about you than any other object in your possession,” explains Martin Frei.
- A central axis set in ruby bearings provides excellent stability for the satellite/retrograde complication. A cylindrical marine chronometer type spring runs vertically around the axis and generates the optimal tension required for the retrograde minutes flyback.
- A minute hand, which also forms a frame for the hour satellites, displays the time in an extraordinary way. Milled from aluminum to exacting tolerances of approximately 3 microns, the whole structure has a total weight of just 0.302g and is counter balanced by a brass weight. This three-dimensional cage offers rigidity as it transfers energy from the cylindrical flyback spring in the top center of the carrousel to the double-star gear underneath.
- A double coaxial star-shaped cam regulates the retrograde mechanism through its gearing and its rotation defines the trajectory of the minute hand. When the minute hand reaches 60, the double star trips a (one of three) hockey-stick shaped spring under the mechanism, which liberates the minute to fly back to the next hour satellite at 0-minutes.
“In terms of the degree of evolution of the satellite carousel, I feel with the UR-210 that we have reached the pinnacle of what we can do with this complication.” explains Felix Baumgartner. “After the presentation of our über complicated UR-1001 Zeit Device, we wanted to experiment again on an imposing scale. The minute hand in the heart of the UR-210 is not just big, it is massive! And yet it presented us with a considerable challenge because it requires fine, delicate workmanship. It envelops the hour satellites and demands machining to extremely fine tolerances.”Martin Frei adds: “More than any other URWERK piece, the UR-210 catches the attention. The eye is inevitably drawn to the winding efficiency indicator… it’s almost a magnetic attraction. The UR-210 is not really a watch but rather a living mechanism grafted onto your wrist. We have nicknamed the UR-210 the Maltese Falcon because we see it as the stuff that dreams are made of .Felix Baumgartner concludes: “The UR-210 represents a serious accomplishment for URWERK. This timepiece opens a new chapter in the evolution of our complications. It doesn’t just measure a universal value in a completely original way, but starts a real dialogue between the watch and its wearer. The UR-210 indicates your personal activity; this is yours and nobody else’s.”
