ABSTRACT:
A water-tight push-piece for a diver's watch comprises locking means constituted by a sleeve fitted inside a head located around a tube intended to be secured to the watch case. This sleeve is not able to rotate but is able to slide on the tube and is provided externally with a screw-thread co-operating with an internal screw-thread on the head, in order to be able to move axially during rotation of the head. A gasket is disposed between the bottom of the sleeve and the tube. When the push-piece is locked, the bottom of the sleeve abuts against the end of the tube thus compressing the gasket.
