Pioneers of Modern Watchmaking: A Collaboration of Innovation

Collaborations between watchmakers who might otherwise be considered competitors have been part of the modern haute horlogerie landscape for nearly three decades. The creation of an advanced timepiece often requires the combined expertise, creativity, and technical knowledge of multiple specialists. In this sense, collaboration has always been an integral part of fine watchmaking, even when it takes place behind the scenes.

By bringing these partnerships into the public eye, watchmakers offer greater transparency and allow enthusiasts and collectors to appreciate the craftsmanship, innovation, and shared expertise behind the timepieces they admire.

Caliber UN-241: A Fusion of Engineering and Innovation

At the heart of this remarkable collaboration is the self-winding Ulysse Nardin Caliber UN-241, an in-house movement developed to power the distinctive wandering-hours satellite display designed by URWERK.

This integrated mechanical caliber combines Ulysse Nardin’s movement-making expertise with URWERK’s unconventional approach to time display, bringing together two distinct horological philosophies in a single mechanism.
