The UR-230 Black Star features Urwerk’s ceramic composite case developed with and exclusively for Urwerk. After the raw texture of the Carbon CTP in the “Eagle” and the mineral whiteness of the ceramic “Polaris”, the “Black Star” concludes the 230 collection triptych on a cosmic note.
Inside the case, the UR-7.30 caliber is encased in a hermetically sealed container resembling a strongbox. The ceramic case and black DLC titanium case back are harnessed to a Vulcanized rubber strap around it.
Produced in a limited edition of just 35, which equates to less than one watch for each global retailer.
