Test method of a thermoelectric element

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.
