Abstract
A device comprises means for distinguishing a short depression from a long depression depending on the period of actuation of a control button (block 14), means for selecting in the case of a short depression a minutes correction mode in which the display advances by one minute for each pressure (block 18) and, in the case of a long depression, an hours correction mode in which the display advances by complete hours as long as the depression lasts (block 19). It further comprises means for defining two different advance speeds, a slower speed (SLOW+60 m) and a faster speed (FAST+60 mn) in the hours correction mode, and means for passing automatically first to the slow speed to advance a first hour and then to the fast speed for the following hours.
