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.
