The container (5) includes a mechanical, wind-up clock or an electronic clock with an accumulator or battery, both with a stopwatch and alarm clock function for displaying the lifespan, for example of a cosmetic product, or also other displays such as applications, ingredients, orders, product information and other information. The container (5) can include a receiving cylinder for introducing an exchangeable refill-capsule containing the cosmetic product in the case of an electronic clock, same is fitted with an electronic display (2) and provides at least the following functions: A: setting the current date and the current lime; B: setting an expiration date; C: clock function: displaying the calendar year, the month, the day and the time; D: stopwatch and alarm clock function, so that product shelf lives of cosmetics and other products with a limited period of use can be monitored, wherein an acoustic alarm signal sounds when the shelf life limit is reached, and the exposure times can also be monitored in this way.

An electronic timepiece includes: a measurement result obtaining section configured to obtain a measurement result of a display target item which is any measurement item among a plurality of measurement items; a display configured to display the measurement result of the display target item; and a display controller configured to cause the display to display the measurement result of the display target item during a display period that corresponds to the display target item, in which the display period is set in accordance with each of the plurality of measurement items.

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 includes a measurement unit which is measuring a predetermined measurement item, a storage unit which stores measurement result information in which a measurement result obtained by the measurement unit is associated with a measurement time when the measurement result is obtained, and a display unit which displays the measurement result and the measurement time by hands.
