Abstract: A testability method (500) for testing the operation of a thermoelectric element (110) of a thermoelectric watch (100) including the thermoelectric element (110), a power circuit supplied by primary storage elements (101) and secondary storage elements (102) so as to move at least one moveable element (190) or display information on an electro-optical display device. The testability method (500) includes steps of applying a heat source (540) to the thermoelectric element (110) so as to make it possible to electrically charge (550) or recharge (550) the secondary storage elements (102) in order to move at least one moveable element (190) or display information on an electro-optical display device, and thus check the functionality of the thermoelectric element (110).
