ABSTRACT:
The watch has at the top edge of its case, on opposite sides, flanges which project radially inwards and the underside of which is at a distance from the watch-glass edge. To close the watch and press the watch glass against a packing resting on an inner case shoulder, there are two shackle-shaped clamping slides which each have two legs and which can be pushed from the two opposite flange-free case sides into the slits located between each of the flanges and the watch-glass edge. When the clamping slides are pushed in, the packing is compressed strongly enough by the watch glass pressing against it, in order to achieve perfect water-tightness. The invention relates in particular to a watch which has a molded case produced from plastic and or rectangular or even oval shape.
