ABSTRACT:
The wrist watch case of this invention includes a caseband-back provided with supports for retaining a movement assembled from above the caseband. The caseband-back is provided with a circular opening having a diameter substantially greater than the diameter of a circle circumscribing the movement. The opening is blocked by a cap which is fixed to the caseband-back by fastening means arranged at the exterior of said circumscribing circle and at a level located above the lower face of the movement. The cap is provided with notches arranged and adapted to cooperate with a wrench supplied to the watch user thereby to open or close the cap and thus permit changing the battery. The wrench may form an integral part of the bracelet buckle.
