ABSTRACT:
A wristwatch includes an assembly comprising a hard plastic seal in the form of a hollow tube in which are mounted a crystal, a movement and face, and a bottom cover. That assembly is inserted as a unit into the bottom end of an opening of a clamping ring. A portion of the opening overlies a portion of the tube to limit the extent of upward movement of the tube in the opening. The opening of the clamping ring includes an inwardly facing groove into which a portion of the tube may project to axially secure the tube. A setting shaft projects through the clamping ring and tube and is surrounded by an O-ring mounted in a recess of the tube. The clamping ring comprises a case and a bezel mounted thereon. Different bezels can be employed to change the appearance of the wristwatch.
