Electronic device fitted with power generators

An electronic device comprising:

• a housing having a first transparent surface and a second transparent surface opposite to the first transparent surface;
• a timepiece movement disposed in the housing and having a display for displaying time through the first transparent surface of the housing;
• a thermoelectric generator disposed in the housing for generating electric power in response to a temperature difference across the thermoelectric generator;
• a pair of solar generators disposed on opposite sides of the thermoelectric generator and disposed on the second transparent surface of the housing for receiving light transmitted through the second transparent surface to generate electric power;
• and electrical power storage means for storing electric power generated by at least one of the thermoelectric generator and the solar generators and for supplying the electric power to the timepiece movement.
