<p>The spacer (3) with the glass (2), the piece (4) with the back (5) and the cap (12) of the watertight watch case are fixed together by two strands of flexible plastic wire (29) of circular section. Each of these strands is engaged by its ends in the two channels of square section which are formed by the rectangular grooves (27), (28), hollowed out respectively in the outer face of the piece (4), all around the latter, and in the inner wall of the flanks of the cap (12), and which open out into the same inter-horn section (23) of this cap. The watertight lining (10), compressed axially between the pieces (3) and (4), normally wedges the ends of the wires (29) in the channels (27, 28), somewhat offsetting the groove (27) relative to the two grooves (28). <IMAGE></p> |
