Family: UN-1xx170h power reserve
The UN-170 is a manual-winding manufacture caliber introduced by Ulysse Nardin in 2013 and remains in production. It features a flying tourbillon at 6 o'clock, paired with a silicon balance spring and silicon escapement for improved magnetic resistance and stability. The movement draws inspiration from a 1922 Ulysse Nardin pocket watch movement and offers a 170-hour power reserve. Part of the UN-1xx family of in-house calibers.
