Abstract
This invention concerns a compass watch as well as a bezel specifically intended to fit out such a watch. The invention comprises at least one time indicating element (4) kinematically driven in rotation by a mechanical or electromechanical horometric movement, and particularly intended to be pointed towards the sun, and direction indicating means (N, S, W, E) arranged on said watch enabling one to know, as a function of the orientation of said indicating means (4), the direction of at least one of the cardinal points, and is characterized in that it includes correction means (52; 16, M) for the positioning of the cardinal points, adapted to take into account the equation of time and to correct any variation between true solar time and the legal or local time of day. The invention is applied to a watch, preferably of the mechanically or electromechanically driven type.
