ABSTRACT:
An analog electronic timepiece includes a dial plate in which an opening is formed, an electric-optical display panel arranged below the opening, and a shutter plate movably mounted between the dial plate and the display panel. The shutter plate is moved to a first position, in which only one of two types of data is exposed, when the above described one data is displayed on the display panel, and is moved to a second position, in which only the other data is exposed so that any not-displayed portions in the display panel is not exposed, when the other data is displayed on the display panel, the two types of data being different from each other in the number of displaying digits for displaying them.
