Abstract
An electronic device has a housing having a first transparent surface and a second transparent surface opposite to the first transparent surface. A timepiece movement is disposed in the housing and has a display for displaying time through the first transparent surface of the housing. A thermoelectric generator is disposed in the housing for generating electric power in response to a temperature difference across the thermoelectric generator. At least one solar generator is disposed on the second transparent surface of the housing for receiving light transmitted through the second transparent surface to generate electric power. An electrical power storage device stores electric power generated by at least one of the thermoelectric generator and the solar generator and supplies the electric power to the timepiece movement.
