A thermochromic element including a thermochromic layer including a binder and a thermochromic pigment chosen to react at a specific temperature so that the pigment passes from a first color to a second color when the specific temperature is reached. The thermochromic layer coats a thermally conductive layer, and is protected by an optically transparent layer that protects it from chemical and physical degradation.

An electronic timepiece of the present disclosure includes a first indicator wheel marked with numerals including a date, a second indicator wheel marked with a plurality of pieces of information, and a dial including a window configured to enable visual recognition of the numerals and the information. The electronic timepiece is configured to switch between a date display configured to use the numerals to display a date, and a function display obtained by combining the numerals and the information.
