Urwerk UR-100V (Wandering Hours)

About this reference

The Urwerk UR-100V in Grade 5 titanium, often referred to as the "Iron," was introduced in 2020 as an evolution of the original UR-100 series and remains in production. Collectors prioritize this reference for its wandering hour complication, powered by the caliber UR 12.02, which utilizes a planetary gear system and a Windfänger airscrew to regulate the automatic winding rotor. The 41mm titanium case features a unique astronomical display with two lateral apertures: one tracking the Earth’s rotation at the equator (555km every 20 minutes) and another tracking the Earth’s orbital velocity around the sun (35,740km every 20 minutes). On the secondary market, this model typically trades between $45,000 and $60,000. A notable production variant is the "Blue Shark," a limited edition of 25 pieces featuring a blue PVD-coated steel and titanium construction, which highlights the model's modular design architecture.
