[0007]

The gist of the present invention for achieving the above object is an electronic timepiece having a dial, a pointer display device, and a transmissive display device between the pointer display device and a cover glass. Further, a coating pattern for covering the pointer of the pointer display device is provided at a specific position of the transmissive display device. Further, the electronic timepiece has a mode switching means for switching between an analog display mode and a digital display mode, and a pointer specific position drive for moving the pointer to a specific position when the mode switching means selects the digital display mode. It is characterized by having means.

[0008]

When the digital display mode is selected by the mode switching means, the transmissive display device on the pointer display device operates and the covering pattern for covering the pointer operates. At the same time, the pointer located under the transmissive display device is moved to a position hidden by the covering pattern by the operation of the pointer specific position driving means, and the appearance is completely digital display and a sporty design. On the other hand, when the analog display mode is selected, the pointer returning means is activated to display the correct time and at the same time the transmission type display device is set to 0.
It becomes FF and becomes an analog clock with a dressy appearance. As a result, a composite display electronic timepiece in which two types of functions and designs are used properly can be obtained.
