URWERK’s history is punctuated with decisive moments. One of these is the Opus project. In 2005, in partnership with Harry Winston, we unveiled one of our most spectacular and enterprising creation: the Opus 5.
Opus 5 is based on the satellite concept of rotating hours. Unveiled in 2005, it was a milestone in much the same way that the UR-103 had been. It gave this crazy type of watchmaking credibility. People saw for the first time, through Harry Winston, what we do here. It gave us a lot of new possibilities.
The hour display on Opus V was a world première. Much of its secret lies in the three small blocks arranged like satellites within a three-dimensional system permanently displaying three hours on the dial. Since each block carries four numerals, two rotational axes are required to display all 12 hours: the first central axis enables each hour numeral to “move past” the minute counter while driving the retrograde hand; while the second reveals the four numerals in accordance with the first rotation.
