<p>#CMT# #/CMT# The object has a light detector (10) i.e. photodiode, arranged at the level of a dial (4). A luminous source (12) i.e. vertical laser microcavity, emits the infrared light beam (16) through a watch glass (2), where the light beam is partially reflected towards the light detector when the light beam is intercepted by the user's finger (D) on the glass. The light detector provides an electric signal to an electronic control circuit (18) for activating a watch function or a function not related to time, when the detector detects the light produced by the source and reflected by the finger. #CMT#USE : #/CMT# Portable object i.e. timepiece e.g. wristwatch. Can also be used for a portable telephone. #CMT#ADVANTAGE : #/CMT# The light detector and the luminous source are easily installed in the watch in a simple, rapid and cost effective manner, and uniquely controls the watch function or the function non related to time, in a simple, rapid and cost effective manner, in all circumstances and even when the time-piece is in the water. The configuration of the object reduces the production cost of the object. The luminous source only emits the light when the source is activated by the user, so that the light source is not constantly turned on, thus saving energy of the object. The object avoids the inadvertent triggering of the function. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a control unit for controlling an electronic function of a timepiece.
