Abstract

The clock face has a mirror (1) at the centre, inside the normal numbers around the dial periphery, with a second set of numbers around the mirror (1), which are printed as reverse images, so that when a light beam is directed onto the dial, it is reflected by the mirror onto an aligned viewing screen and the numbers around the mirror (1) appear the right way round. the light source (4) is clamped to the clock and is carried by a leg to be spaced above the dial, with a battery for the light also supported with a battery for the light also supported by the clamp.
