Collectors value this reference for its unique reversible case construction, which utilizes a complex series of linkages to allow the case middle to flip 180 degrees, protecting the sapphire crystal. It features the caliber UR 8.01, a self-winding movement utilizing Urwerk’s signature wandering hour complication with a rotating satellite carousel and a pneumatic turbine system to regulate the winding rotor. The case is crafted from grade 5 titanium with a textured \"dragon skin\" finish. On the secondary market, the UR-T8 typically trades between $85,000 and $115,000 depending on condition. A notable variant is the \"Colibri\" edition, which features intricate hand-engraving by master engraver Emmanuel Esposito, distinguishing it from the standard 60-piece titanium production run."},
