Abstract
A watch is constructed with a front transparent dial face for displaying the time, such as a liquid crystal, a rear watch mechanism for controlling the display of visually perceptive indicia of the time in the transparent dial face, and an interior hollow compartment located between the front transparent dial face and rear watch mechanism. A visual display of the user's choice, such as a photograph, can be inserted by the user into the compartment in juxtaposed relation to the transparent dial face and is observable to the eye through the transparent dial face simultaneously with the time display. The visual display can be inserted into the compartment by itself, or can be positioned on a plate or tray and then slid or pivoted into the compartment. Means are provided to secure the visual display in place after insertion into the compartment.
