To this the whole thickness of a timepiece having a means for detecting positions of at least two needles.

A first hand 5 and a first pipe 1 compose a part of an angle position indicating movable part MR1 for supporting a plate 9 cooperating with a first sensor 11 for generating a position signal relative to the hand 5 as a result of discontinuity on constitutional members of the plate 9. A second display hand 6 coaxial with the first hand 5 and a second pipe 2 are connected to a second angle position indicating movable part MR2 similar to the WR1. The second MR2 is installed side by side with some distance from the MR1.
