Ziiiro

The concept of the first Ziiiro Watch is a clock face without hands or markings, but a constantly changing pattern of rings indicating the passing of time. The main theme is minimalism, so there are no distracting elements in the design and after a short time you will acquire a feel for reading the time.

If you want an uncommon and beautiful clock on your wrist, then this watch concept, featured on many websites such as Engadget and Yanko Design, is just the thing.
