Not only sunlight but any kind of light is converted into electrical energy by the solar cell under the face and stored in a rechargeable secondary battery. No battery change is required as in quartz watches.
The watch has a power reserve, so that - once fully charged – it runs for 6 to 12 months. Even if it is stored in complete darkness during this time.
