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. This ‘Gunmetal’ version – a limited edition of just 5 pieces – adds an even stronger monochrome aesthetic with its bracelet, which was developed specifically for URWERK. The radical UR-210 Gunmetal is uncompromising – it will be love at first sight for aficionados of avant-garde horology.
