Embodiment Construction

[0022] Generally, a chronograph according to the invention is used in a wristwatch as shown in FIG. 1 .

[0023] The chronograph according to the invention is incorporated in a multifunction watch 1, which generally consists of a dial 2, a knob 3, for example a first hand 4 indicating hours, a second hand 5 eg indicating minutes and a A display device 6 of the type described in European patent application EP0460526. These various parts are contained in a case or structure 7 attached to the strap 9 .

[0024] figure 2 Represent according to the internal structure block diagram of timer of the present invention, the preferred embodiment of this timer is shown in Fig. 1.

[0025] Basically, in addition to the components described above with reference to FIG. 1, the structure 7 also includes an antenna 10, a GPS receiver 11, data processing means 12, selection means 13, data input means 14, motor 15, internal clock 16 and a power supply17.

[0026] The antenna 10 is arranged t...

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.

Description

technical field [0001] The present invention relates to a timer comprising a GPS receiver arranged to indicate the direction from a "source" location where the GPS receiver is located to a "target" destination or location. Background technique [0002] Timers capable of indicating a particular direction are already known. As an example, reference may be made to European patent application EP 0721155, which discloses a timer indicating the direction of Mecca. This application discloses an analog timepiece incorporating a compass for providing a reference axis (the reference axis being provided by the direction of magnetic north). [0003] One problem in chronographs incorporating a compass is that the magnetic environment of the chronograph assembly will interfere with the constant magnet associated with the compass. This problem becomes especially inconvenient when the hour hand moving part includes a magnetic substance. An imperfect solution to this problem is to move th...
