This time we want to represent your attention stunning watch concept. The ASIG Concentric watches by Simon Williamson embrace their design in all its hubless glory. Each hand comes in a ring-shaped design that rotates on an invisible axis. Outcrops on these rings form the “hands” of the watch that allow you to tell the time despite the presence of any numeric markings on the watch’s face. Really stunning!
