UR-210 RED GOLD

Product description

The UR-210 gets a regal look with an 18k 5N red gold case!
A limited edition of 75 pieces, initially launched in 2013. The UR-210 RG quickly became one of the most popular versions of the 210 family.
This example we have to offer comes in like new condition, backed with a Pre-Owned two-year international warranty, new textured rubber and velcro strap, plus an original URWERK box.The UR-210’s satellite complication with the retrograde minute is 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's satellite. This lightning-fast retrograde system is based on three key elements:
• 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 minute's flyback.
• A minute hand, which also forms a frame for the hour satellites, extraordinarily displays the time. Milled from aluminium to exacting tolerances of approximately 3 microns, the whole structure has a total weight of just 0.302g and is counterbalanced by a brass weight. This three-dimensional cage offers rigidity as it transfers energy from the cylindrical flyback spring in the top centre 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.Flip the UR-210 over to reveal the turbine-assisted winding regulator through a sapphire window. Position the disc to REDUCED” to engage the rotor damping system. The 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 entirely, and the UR-210 runs off reserve power and may require manual winding.CREATORS THOUGHTS:
Felix Baumgartner - "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."
Martin Frei - "Gold provides a unique feeling and emotion thanks to its density and its special appearance . In all the ancient and modern civilizations, gold was regarded as the material of the Gods. For me, as a trained sculptor and painter, touch is the first sense. This certainly explains my visceral attraction to gold. I like its solid, heavy, reassuring and eternal character “
Condition Rating UR-1: As new, with no or very few signs of wear, the movement is serviced and in working condition.
