摘要:
Waterproofing of a watchcase is achieved by a sealing ring disposed between the periphery of the watch glass and a bezel portion of the case and confined between the glass holder ring on which the watch glass rests and an inturned lip portion of the bezel which retains the watch glass. By being disposed between the periphery of the watch glass and the bezel, the sealing ring is concealed from view by the inturned lip portion of the bezel and a more attractive watch is thereby achieved. A second sealing ring is provided between the bezel portion of the case and the case back to provide a seal therebetween.
