Abstract
An electronic timepiece displaying both the time and the temperature. A transducer which may take two positions is provided to reach this result: the first position incorporates the transducer within the timepiece and allowing the correction of the frequency drift of the time base which determines the time the second position projecting the transducer out of the timepiece case in order to measure, for example, the temperature of the ambient air. There is also provided an automatic switching system which adapts the transducer to the frequency correction or to the temperature measurement depending on the position of said transducer.
