Abstract
The arrangement (42) according to the invention is formed by a watch comprising a dial (8) on which is shown a map (14) centered on a given geographic location, Mecca in particular. The arrangement (42) comprises a device (48) for indicating the direction of the terrestrial magnetic north and a device (16) enabling the angular positioning of the map in the general plane of the arrangement (42) corresponding to the plane of the dial (8). The different geographic regions shown on the map (14) are graphically arranged so that any point whatsoever of the contours of such regions substantially shows an angular spread (.OMEGA.), relative to a center of reference (22) corresponding to the above-mentioned given geographic location and to a reference direction (24) equal to the magnetic azimuth of the great circle passing through said point and the reference point (22) augmented by 180.degree.. In another embodiment the angular spread is equal to the geographic azimuth of the great circle passing through said point and the reference point (22) augmented by 180.degree..
