Abstract
The invention relates to a watch comprising a device for indicating the temperature (16) of the environment in which the watch is situated comprising a first series of thermochromic liquid crystal temperature sensors (18) facing a first temperature scale (20) arranged in such a way that the reading given by the sensors (18) of the first series, in combination with said scale, is directly representative of the temperature of the environment in contact with the sensors, and wherein the device differentiates the temperature indicated by the sensors according to whether the watch is worn or not worn.
