One extra strap will be added to each of the five watches Excelsior Park is designing a new line, inspired by the 50’, the golden age of watches for science, technology, and industry. We are sharing a few concept watches from our designers as a special 5 pieces Atelier Collection, each a “piece unique” numbered 1 of 1. They express classic design themes but are created for a new generation of watch collectors.
