Ulysse Nardin UN-178

The UN-178 is an automatic movement manufactured by Ulysse Nardin. Introduced in 2015, it remains in production as part of the UN-1xx in-house caliber family. The movement features an Anchor Tourbillon with constant force escapement—a distinctive mechanism that won the Tourbillon category at the 2015 GPHG awards. This complication represents Ulysse Nardin's commitment to technical innovation within their proprietary movement line.
