UR-210

The UR-210


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. Never has a timepiece displayed such feedback and attachment to its owner.

Swiss timepieces satellite watch UR-210

Flyback minute hand

The UR-210 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.

Retrograde system

This lightning fast retrograde system is based on three key elements: a central axis set in ruby bearings ; a cylindrical marine chronometer type spring running vertically around the axis; a double coaxial star-shaped cam regulating the retrograde mechanism.

World-first complication: Winding efficiency indicator 

This genuine indication calculates the difference between energy consumed and energy created over the last two hours. If the indicator points towards the green zone, it is a sign that the mainspring is being replenished.

Power reserve indicator

39h power reserve.

Meticulous
craftmanship

“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.”
