ABSTRACT:
A sealed watch case comprises an assembly wherein a gasket bead is applied to predetermined locations on the watch case and caseback prior to assembly. The gasket bead consists of a plastic or elastomeric material generally polymeric in nature which is applied in the form of a gasket bead to the crystal seat in the watch case, the caseback seat in the watch case or either predetermined locations in the caseback. The bead provides a fixed, formed in place and flexible gasket arrangement between the components of the watch case assembly to prevent entry of foreign matter into the watch case. The bead becomes an integral part of the watch case assembly, yet disassembly does not impair the effectiveness of the bead upon subsequent reassembly.
