A timepiece that uses disks (16, 28) having sharp zones of contrast (20, 22, 30, 32) of visual design intensity to indicate time intervals when the sharp zone of contrast is aligned with the time interval indicator markings (14) or traditional time indicator positions on a non-rotatable frame. The disks (16, 28) of the chronograph are continuously graduated in visual design intensity from an area of greatest intensity (20, 30) to an area of least intensity (22, 32) to form a sharp zone or line of contrast (24, 34).
