ABSTRACT:
The timepiece (42) includes within the case (44) an electronic compass and a sighting device formed of two sighting marks (14, 15) arranged in the upper portion of the case (44) diametrically opposite each other and defining a reference axis of the case (44). The optical means formed by three light emitting diodes (54, 55, 56) are arranged on the surface of the case (44) in a peripheral region situated at six o'clock for warning or informing a user performing a sighting that the reference axis of the sighting device is aligned with a given azimuthal direction. In another embodiment, instead of the optical means, acoustic means or a buzzer are provided, capable of providing a vibration which is audible or perceptible by a user's body.
