This UR-230 “Black Star” is original in more ways than one. First, there is its structure. Calibre UR-7.30 powering this creation is protected by a hermetic titanium container designed as a mechanical safe. Surrounding this highly protected heart, a composite ceramic case and a black DLC titanium back form the UR-230’s shell: “I love the aesthetics of ceramic and its clean, precise look. It’s a material that’s hard, shiny, beautiful… and incredibly fragile. A single impact and it cracks – yet I didn’t want to give up on this option”, explains Felix Baumgartner, master watchmaker and co-founder of URWERK. “We had to find a solution to fulfil this desire without making any comprises.

The original, high-performance case of the UR-230 “Black Star” ismade from a laminated composite ceramic developed specifically for URWERK: layers of braided ceramic, fibreglass and carbon fibre have been integrated into a polymer matrix. When machined, this unique ceramic reveals a shiny relief. Its flat, smooth surface is illuminated with sparkling dots, creating a dense, vibrant black-light texture.
