Reversible watch

An assembly comprising an object, a support and, on said support, a fixing element for removably connecting said support to said object and defining a pivot axis between said object and said support in such a way that said object and said support can be reversed independently of each other, and in order to present alternately a first face and a second face of said support, said faces lying on either side of a mid-plane in a vicinity of said fixing element, when said object and said support are mutually arranged in a first or second stable position, respectively, wherein

• said fixing element has a pivot comprising a body connected to said support, and a base formed at its free end, and
• a cavity is formed on in said object, said cavity comprising
• a first opening designed to allow said base to be inserted into said cavity and
• being continued by an elongate second opening extending transversely with respect to the direction of said pivot axis and parallel to said mid-plane in a stable position, said elongate second opening being designed to guide said pivot and permit a relative movement of said object and of said support to bring them to a stable position,
• said support also comprising retractable locking means designed to engage with matching cavities in said stable position and to hold the assembly in said position.
