ABSTRACT:
An adjustable watch crystal apparatus includes a watch body, a flexible lens having a changeable amount of curvature, and means for adjusting the amount of curvature of the flexible lens. The flexible lens is positioned upwardly adjacent a watch face for adjustably refracting light to make the watch face legible for a user with farsighted vision. The flexible lens includes top and bottom sides having convex configurations, an outer edge, and a center. The adjusting means includes a collar member attached to the watch body for retaining the flexible lens outer edge. In one embodiment, an adjustment screw controls the curvature of the flexible lens by moving the flexible lens center between adjacent-center and displaced-center configurations. In another embodiment, the collar member moves perpendicularly to the watch face to control the curvature of the flexible lens by moving the flexible lens outer edge between displaced-edge and adjacent-edge configurations.
