摘要： The invention relates to a portable precision watch (1) which has in addition to time functions (11) a GPS receiver (3) with an aerial (4), an evaluation electronic unit (5), a compass (6) a target co-ordinate memory (9), an input element (7) and a display element (8). The co-ordinates of the position (S1, S2) and the direction (SZ) to the destination are calculated with the evaluation electronic unit and are visualised immediately in the display element in the form of a vector display (V). A very compact precision watch is consequently produced, in particular in the form of a pocket watch or a wristwatch, which can be worn by individuals anywhere and displays immediately world-wide the direction to any destination (Z1, Z2).
