ABSTRACT:
An electronic watch having an electronic circuit arranged to control at least one function of the watch other than the usual functions of time indication, in which the manipulation of a time-setting rod and/or the position of movable elements of the watch at a given moment define the parameters which, alone or in combination, correspond to access codes which are recognized by the electronic circuit for accessing the advanced features. The present invention proposes to control the advanced features of the watch by means of a single time-setting rod. The time-setting rod of the preferred embodiment detects four parameters for determining an entered access code. These parameters are: (1) the position of the time-setting rod; (2) the rotation of the time-setting rod; (3) the direction of rotation of the time-setting rod; and (4) the rotation velocity of the time-setting rod.
These four parameters, taken individually or in combination, can define access codes for the various features of the watch using a single control.
