Ulysse Nardin UN-205

The UN-205 is a manual-winding movement manufactured by Ulysse Nardin, introduced in 2013 as part of the UN-2xx family. It features a Karussel tourbillon with a silicon balance spring and the brand's proprietary Dual Ulysse escapement, built in a flying configuration. The movement's distinctive winding system uses the bezel to wind the mainspring, while the front bezel also adjusts the time. Part of the Freak Cruiser lineage, it was produced in-house by Ulysse Nardin and has since been discontinued.
