Abstract (en)
[origin: EP0201791A2] In a time indicating device having a numerical dial, on which at least one marking which is adjustable relative thereto indicates the appropriate time, at least one light source for generating this marking is arranged at a distance from the numerical dial and at least one object casting a shadow on the numerical dial or at least one transparent surface in an otherwise opaque region or the like is provided. By means of a circuit arrangement or a clock mechanism, the light source or the shadow-casting object or the light-permeable surface is moved in time sequence relative to the numerical dial. <IMAGE>
