Abstract
A winding button has an internally threaded skirt into which a sleeve is fully screwed leaving part of the thread for screwing the button on a pendant tube. When the button is unscrewed, a spring acting between a winding-stem shank and the sleeve biases the sleeve and button to an outer position in which the shank is coupled for rotation with the sleeve. Sealing joints are placed between the sleeve and the button and the sleeve and the pendant tube.
