ABSTRACT:
An electronic watch having an electronic circuit to perform advanced features that is able to distinguish between a first case in which an access code for entry into a programming mode has been correctly entered and the programming operation has been correctly done, from a second case in which the access code has not been correctly entered and/or the programming has not been done correctly. Access to a programming mode of a perpetual calendar feature built into the watch is controlled by requiring at least one manipulation of a time-setting rod in view of its attribution to at least one function other than the functions of correction of the date and day, and to control the watch in the manner of an ordinary watch in the second case and to attribute, in this case to at least one manipulation of the rod, the functions of correction of date and day.
