Abstract
A wrist carried instrument includes a rechargeable electric energy source for providing power to the instrument. The energy source is recharged by a pair of generators, both operatively coupled to the source and generating complementary recharging currents from different physical phenomena. The first generator may be a photo-electric cell generating a recharging current in light such as exists from the sun in summer, while the second generator may be a thermoelectric element generating a recharging current from a temperature gradient such as exists in the dark or winter.
