One thus obtains a movement in which the direction of rotation of crown (12) is selected by the user by his prior action on selection device (13).
Abstract: To obtain a degree of freedom in a design of a circumference part of a timepiece armor assembly, and provide a watch whose degree of freedom in a size of a dial is high. A timepiece armor assembly is formed of an armor case of one-piece structure in which a case bottom wall and a case band part provided with a crown have been monolithically molded and of an armor cover which has a transparent member and an edge member supporting a circumference edge of the former member and has been mounted to the case band part. In the armor assembly, a timepiece movement which has a movement main body and a winding stem attached to this main body so as to be capable of being inserted into or detached from it and connected to the crown, and a dial are built, and a winding stem attachment/detachment mechanism which makes an insertion/detachment of the winding stem into/from the main body possible is provided.
