Abstract
A timepiece (7) including hands (4, 5), direction determining means (10, 11, 14, 12) including data input means (14) arranged for inputting the geographical coordinates of a "target" location in data processing means (12). This timepiece is characterized in that said direction determining means are formed of an antenna (10) and a GPS type receiver (11) for determining the geographical coordinates of the location in which said timepiece (7) is situated, and in that the 6 o'clock-12 o'clock axis of said timepiece (7) is used as a reference axis, and in that at least said first hand (4, 5) is arranged so as to be able to indicate the direction of the "target" location with respect to said reference axis. Such a structure is improved in that it does not need to refer to magnetic north to determine the direction of the "target" location.
