Abstract

A control member such as a push button or winder for a thin water-tight watch has a tube fitted to the watch case, and a control rod movable in the tube by a manually movable head fixed to the rod. Surrounding the tube axis is a sealing O-ring making sealing contact with and around a surface of the tube. The ring compressed axially of the tube is disposed between the head and tube in a housing defined in part by first and second faces on the head. The first face is annular in a plane at right-angles to the tube axis and the second face is cylindrical centered on the tube axis and spaced radially of the tube from the ring.
