Abstract
A timepiece, such as a wristwatch, includes a casing, a carrier disc disposed in the casing, a glass mounted elastically to the casing in front of the carrier disc, and control switches in the form of piezoelectric sensors each sandwiched between an outer edge of the glass and a forwardly facing edge of the carrier disc. The sensors are electrically connected to an electrical control circuit of the timepiece and are actuable in response to being compressed by a rearward pressure applied to the outer edge of the glass.
