Ulysse Nardin x Urwerk UR-Freak Titanium Wristwatch

Partially verified

The Ulysse Nardin x Urwerk UR-Freak is an automatic wristwatch produced in a limited edition of 100 examples. The watch features a 44mm sandblasted titanium case and is powered by the Calibre UN-241, an automatic movement developed through a joint collaboration between Ulysse Nardin and Urwerk. The timekeeping mechanism utilizes a carousel-driven movement, a platform associated with the Ulysse Nardin Freak, which is combined with a wandering hour display designed by Urwerk. The orbital display system incorporates three arms, each carrying domed hour discs that rotate along a 60-minute arc. The design includes a crownless configuration and is paired with a yellow ballistic-textured rubber strap. The watch was selected as a finalist in the Complication category at the 2026 Grand Prix d’Horlogerie de Genève.

Object description

Case and Display

The UR-Freak is housed in a 44mm sandblasted titanium case. The watch utilizes a crownless architecture that relies on a carousel-driven movement to manage adjustments. The dial is characterized by a grey color palette and incorporates an orbital display system. This system consists of three arms that support domed hour discs; these arms move along a 60-minute arc to indicate the time. The visual presentation of the movement is exposed, following an aesthetic associated with Urwerk's mechanical style.

The strap is constructed from yellow ballistic-textured rubber and features a rigid insert labeled with the model name 'UR-FREAK'. The overall design integrates elements from the Ulysse Nardin Freak platform with a specialized wandering hour complication, marking a collaborative effort between the two manufacturers. The exhibition caseback allows for visibility into the movement components from the rear of the watch.

Movement and Development

The timepiece is driven by the automatic Calibre UN-241. This movement was the result of a three-year development cycle involving a joint effort between Ulysse Nardin and Urwerk. It serves as the mechanical core for the watch's unconventional time display, which eliminates the traditional crown and utilizes a carousel configuration to power the rotating hour arms.

The movement design represents the integration of Ulysse Nardin's existing Freak architecture with Urwerk's mechanical wandering hour display technology. The technical development of this caliber led to the watch being recognized as a finalist for the Complication category at the 2026 Grand Prix d’Horlogerie de Genève, documenting the project's industry-facing technical claims.
