ABSTRACT:
An apparatus for indicating time featuring a face having a stationary helical member positioned about a central point so that the distance between any point upon the helical member and a horizontal base plane increases in a clockwise direction around the circumference of the helical member. The face also includes a step member connecting the ends of the helical member along two radially extending common edges to form a continuous surface. At least one of these edges corresponds to the 12 o'clock position of the face thereby defining an indicia from which elapsed time is measured. Also, the face can include a plurality of members mounted upon a horizontal base plane and positioned about a central point. Each member is made of first and second planes of different areas which are angled with respect to the base plane and which intersect to form a common edge therebetween. The edges of the members extend toward the central point or terminate prior to that point to form a central face opening. The horizontal base plane forms the outer perimeter of the face to facilitate attachment of a crystal. Furthermore, the apparatus is equipped with hands which rotate relative to the face and means for attachment to a watchband, wall or other such surface.
