1. A test method for testing the operation of a thermoelectric element of a thermoelectric watch; said thermoelectric watch comprising said thermoelectric element, at least one moveable element or display information on an electro-optical display device; a power circuit supplied by primary storage elements, forming a battery, and secondary storage elements, formed by condensers, and supplying the thermoelectric watch so as to move said at least one moveable element or display information on an electro-optical display device; said primary storage elements and secondary storage elements being configured to receive electrical energy from said thermoelectric element; said test method comprising steps of:
moving the thermoelectric element away of a heat source;
interrupting supplying the power circuit by said primary storage elements;
electrically discharging said secondary storage elements; then
applying a heat source to said thermoelectric element; said heat source having a temperature higher than the temperature of the environment so as to
electrically charge or recharge said secondary storage elements, and,
supply said thermoelectric watch by said secondary storage elements so as to move said at least one moveable element or display information on an electro-optical display device.
