The second installment in the 230 series inaugurates a color and a material that both depart from Urwerk's historical language. Carved from a block of polar white, enhanced ceramic, the UR-230 Polaris is made of sheets of woven ceramic intertwined with fiberglass plies. Used in aerospace, medical, and watchmaking industries, this new and high-performance material combines the advantages of each of its constituents. “The usual ceramics are hard, but it’s also what makes them a liability, says Felix Baumgartner, master watchmaker and co-founder of Urwerk. "These materials are heat sintered, which makes them prone to shattering in a case of a strong impact. We had to go past that limitation. So we decided to develop a ceramic, by and for ourselves. Thanks to the glass fibers it contains, it doesn’t break.” With a 48 hour power reserve and white vulcanized rubber strap, this timepiece will be created in a limited edition of 35 pieces for the world.
