Ulysse Nardin NARDIN-UN-250

The Ulysse Nardin caliber UN-250 is an automatic movement manufactured in Switzerland and the first automatic caliber in the Freak line of watches. It features Incabloc shock protection and operates with an automatic winding rotor. The movement incorporates innovations originally developed for the InnoVision 2 concept watch, which Ulysse Nardin presented at SIHH in 2017. This automatic Freak caliber introduced crownless operation to the collection, allowing winding and time-setting through the caseback mechanism.
