  • Patent number: 4734895
    Abstract: A novelty watch construction is disclosed. The face of the watch or dial includes first and second members, the first one being substantially smaller in diameter than that of the watch crystal. It overlies the second dial in spaced parallel relation, to form an interstice therebetween. The second dial member has a diameter approximating that of the crystal. A pendulum-like support is mounted on bearings between the first and second dials for orbital movement relative to the dial members and hands, the support carrying an exposed jewel or jewels which move within the circular area between the periphery of the first and second dial members. Where the jewel is provided with facets, such movement causes a continuously changing sparkle effect.
