Abstract:
    The invention concerns a method which consists in producing an elastomer material (9) by overmoulding between the middle (2) of a watch case and a support ring, in particular an encasing band (3) designed to support the watch movement, thereby reducing the internal forming and internal machining stresses of the middle, while enabling an accurate positioning of the watch internal elements relative to the middle. The elastomer element (9) can also provide tightness with the control stem and/or the base and/or the glass of the watch.
