Pure racing meets pure emotion. This is coblor, a manufacturer from Germany that enables motorsport enthusiasts to wear an almost 100-year history of the world's most famous race track, our Nürburgring, on their wrist. Generations of the world's best drivers and countless world champions have raced over the asphalt that now adorns the dial of a chronograph. Of course, this means that each of the 500 limited edition watches is truly unique. An idea, coupled with innovation and a good dose of courage to create something special, has resulted in a genuine world premiere. In order to do justice to the genuine and historic race track asphalt in its value, we have not compromised on quality in the manufacture of our watch. We have used the highest quality materials such as titanium (grade 5), sapphire, ceramic and natural rubber. The watch is produced exclusively in the historic Swiss watchmaking town of La Chaux-de-Fonds. Our movement: The cob.01. Produced by the renowned concepto manufactory.
