Ulysse Nardin Freak ONE Guilloché gives its rotating hour disc a sand-toned pattern

Ulysse Nardin’s Freak ONE Guilloché adds a sand-toned, diamond-pattern hour disc to the collection’s rotating architecture. Presented in September 2026, it brings traditional decorative language into a watch whose movement itself indicates the minutes. Neutral colours draw attention to the changing relationship between the patterned disc and the exposed mechanism.

The 44mm titanium case is matched to a light-grey ballistic-textured rubber strap. Automatic calibre UN-240 combines a flying carousel, DIAMonSIL escapement and Grinder winding system, with a stated 90-hour power reserve. Time is set through the bezel rather than a conventional crown. Reference 2403-500LE-4A-GUI/3A is limited to 99 pieces.
