Design submitted by Peter from the UK.
The idea for this watch design was inspired by the rings of a tree which tell how old the tree was when it was cut down. This watch uses rings to count the time in a similar way.
To tell the time you push the button on the side which illuminates the rings, count the rings from the middle to tell the time. Solid rings indicate full hours, partial rings for partial hours in an intuitive manner.
The design and the interface are very simple and clutter free and would appeal to sophisticated types and tree huggers of course!
