1998 (?) - Swatch Autoquartz Chrono Alarm Musicall Solar Stop watch

Swatch begins (?) production of a plastic-cased with a dual power sources “autoquarz” and solar cell. The rotating balance for the autoquartz is visible through the clear plastic back.

The title of the watch and the instruction manual describes the watch as a solar watch, “Swatch Solar need 15 min. to be fully charged at sunny daylight.” It is not clear that it is, since no solar cell surfaces are visible.
