The electronic watch (1) indicates the time using two hands (2, 3). This electronic watch includes an electronic compass (10), a processing unit (13) with a microcontroller (15) for calculating the direction of North on the basis of detection signals provided by magnetic sensors of the compass. The watch also includes motorised means (16) driving the hands controlled by the processing unit in order to place the hands (2, 3) in a time mode, a selected direction mode or a selected compass mode, and a manual control member (4) connected to the microcontroller processing unit. This control member (4) can be manually activated in a selection position in order to perform selection from the time mode to the direction mode and/or to the compass mode. In the selected direction mode the control member (4) can be pulled out into a stable setting position for setting, via the two superposed hands (2, 3), a direction parameter of a pre-programmed geographical place as a function of the geographical place where the watch is located. In a selected compass mode, the two hands are positioned in opposition to indicate the direction of North.

What is claimed is: 1. An electronic watch with an indication of the time by at least two hands, including: at least one terrestrial magnetic field sensor of an electronic compass integrated in the watchcase, a processing unit with a microcontroller for calculating the direction of North on the basis of detection signals provided by the magnetic sensor, motorised means driving the hands controlled by the processing unit in order to place the hands in a time mode, a selected direction mode or a selected compass mode, and a manual control member connected to the microcontroller processing unit, wherein the control member can be manually activated in a selection position in order to perform selection from the time mode to the direction mode and/or the compass mode, or in a setting position from the selected direction mode so as to set, by means of at least one of the two hands, a direction parameter for a pre-programmed geographical place as a function of the geographical place where the watch is located, and wherein in the selected direction mode, the two hands are in a superposed position or in opposition to indicate the direction of the pre-programmed geographical place, whereas in the selected compass mode, the hands are positioned, contrary to the direction mode, in opposition or in a superposed position to indicate the direction of North. 2. The electronic watch according to claim 1, wherein the control member is an electronic stem crown able to be pressed in from a rest position to an unstable selection position against spring means, and to be pulled out from a rest position to a stable setting position in order to move the two superposed hands, by rotating the crown, into the selected direction mode to a marking on the watch dial or on the watch bezel corresponding to the direction parameter to be set. 3. The electronic watch according to claim 2, wherein it includes a bezel on which angular markings from 0 to 360�� are shown in the clockwise direction over the entire periphery of the bezel from a 12 o'clock position on the watch. 4. The electronic watch according to claim 2, wherein the processing unit with the microcontroller is programmed such that, when the control member is pressed a first time, the direction mode is selected to indicate a direction of a pre-programmed geographical place by using the two superposed hands, and that when the control member is pressed a second time within a predetermined interval of time, the compass mode is selected to indicate the direction of North using the two hands arranged in opposition, and without any action of the control member after the predetermined time interval, the time mode is selected. 5. The electronic watch according to claim 1, wherein it includes a wristband on which several geographical places are shown, each with a numbered reference defining a geographical azimuth relative to the pre-programmed geographical place, the geographical azimuth being the direction parameter to be set in the selected direction mode. 6. The electronic watch according to claim 3, wherein the processing unit with the microcontroller is programmed such that, when the control member is pressed a first time, the direction mode is selected to indicate a direction of a pre-programmed geographical place by using the two superposed hands, and that when the control member is pressed a second time within a predetermined interval of time, the compass mode is selected to indicate the direction of North using the two hands arranged in opposition, and without any action of the control member after the predetermined time interval, the time mode is selected.
