Abstract

A timepiece includes a rotatable bezel mounted on the housing. A storage area inside the housing contains a plurality of folded or crumpled sector elements. The sector elements each have an apex which is attached to a curved spring-like wire and a base which is attached to the housing. Rotating the bezel causes detents in the bezel to push the wires out of the storage area and causes the wires and the sector elements to cover a conventional solid dial face which is mounted in the housing thereby changing the appearance of the dial face. The sector members may have various indicia formed thereon.
