ABSTRACT:
A timepiece that uses disks having sharp zones of contrast of visual design density to indicate time intervals when the sharp zone of contrast is aligned with time interval indicator markings or traditional time indicator positions on a non-rotatable frame. The disks of the chronograph are continuously graduated in visual design density from an area of greatest density to an area of least density to form a sharp zone or line of contrast. The disks are located so that when the sharp zone or line of contrast is aligned with the time indicator markings or positions on the frame, thus displaying the time in an accurate fashion that is easily and quickly discernable even for individuals that are poor sighted. In addition, the timepiece presents such a strikingly novel design that it makes an aesthetic statement that is desirable for use by individuals with no sight problems.
