Abstract
Abstract A timepiece having a casing provided with a lateral window, opening on its lateral face, in which appear the indications of a display device, the casing being arranged in such a way as to be capable of occupying two different positions, in which opposite faces of the casing are turned over one with respect to the other. In each position one or the other of said opposite faces is visible, and commutation means are provided for ensuring that, in one of the said positions of the casing, the time indications are displayed in one direction while, in the other position of the casing, they are displayed in the opposite direction, so that the reading of the time can be effected in either of said positions of the casing.
