The portable electronic device, preferably a wristwatch, includes a radiofrequency signal receiver for receiving, in particular, GPS signals via an antenna, a magnetic compass, a microprocessor data processing unit for processing data provided by the receiver and the compass, and storage means in which almanac and ephemeredes data relating to satellites is stored. The compass is arranged for provide an orientation signal to the data processing device. In this manner, the unit can control means for indicating a direction to indicate a preferred orientation for searching for satellites visible to the user in a reading position of the watch. These indicating means can be formed by the time indicating hands moved above a watch dial. The preferred orientation is calculated by the processing unit on the basis of the almanac and ephemeredes data, time data and the orientation signal.

The method relates to the input of a security code by means of a touch screen of an electronic device such as a watch for access to a specific function, an apparatus or a given location. This touch screen comprises control keys, which can be activated by a manual action of a user using a finger or a stylus. Each key is linked to a microprocessor unit of the electronic device. The method comprises steps which consist of placing a finger or stylus on a key of the touch screen, which represents a first reference of the code to be entered, moving the finger or stylus from the first reference to a key of a second reference over a specific trajectory through the microprocessor unit, keeping the finger on the second reference for a given period of time or detecting a change in trajectory of the finger in the area of the key of the second reference to be input, moving the finger from the key of the second reference to a key of a third reference over a specific trajectory, and removing the finger or stylus from the touch screen to validate the entered code and access to the function, apparatus or given location.
