The timepiece includes sunrise and sunset indicating means taking account of seasonal variations, said means include a sphere reproducing the terrestrial globe, a shell arranged concentrically to the sphere and arranged to demarcate one portion of the terrestrial globe where it is night from another portion where it is day by indicating the position of the earth's terminator. The sphere is arranged to be driven by the movement so as to rotate at the rate of one revolution per 24 hours about a first axis of rotation oriented parallel to the plane of the dial, and the shell is mounted to pivot about a second axis perpendicular to the plane of the dial. The sunrise and sunset indicating means also include an annual cam arranged to be driven in rotation by the movement at the rate of one revolution per year, the cam having a profile representative of the tilt of the sun relative to the equatorial plane.
