The watch case is delimited by an upper face (3), a back, and a lateral face (4). A central opening (2) passes through the case thereby uniting the upper face with the back. A housing for a clockwork movement is at least partially arranged in a projecting part (7) of the case, to which part is fixed one end of a bracelet (8). The movement drives two discs (9, 10) in rotation about the opening (2) in order to display the time. A clasp (20), forming part of the case, includes a plate (22) which is applied to the back of the latter, and a receptacle (23) containing another movement and penetrating into the central opening (2), is fixed to the other end of the bracelet (8). A locking device (31, 32, 35, 36, 39, 40), controlled by a button (30), makes it possible to attach the plate (22) and the clasp (20) to the case or free them therefrom. The two movements can display, for example, the time in two different time zones. <IMAGE> |
