A watch for indicating the direction of a predetermined locality from a plurality of defined geographic regions. Such watch comprises an arrangement (28, 40) for detecting the direction of terrestrial magnetic north and means (22, 46, 14) for indicating the direction of a predetermined locality from any geographic region whatsoever comprised within a plurality of defined geographic regions. Moreover the watch comprises means (18, 19, 20) operable by a user of the watch in order to furnish a code number to an electronic managing and control unit (22). This number, chosen among a plurality of numbers, forms a code corresponding to the geographic region in which the user is located. With the help of such code number, the electronic unit (22) can determine the mean magnetic azimuth corresponding to the region in which the user is located by means of a memory (26) in which is stored a plurality of mean magnetic azimuths respectively corresponding to said plurality of geographic regions.
