ABSTRACT:
In a watch winding crown assembly of the type with a push-button axially displaceable relative to a crown body, the crown body has an integral cylindrical shank slidably and rotatably mounted in a pendant tube, with an interposed annular seal. The push button has a cylindrical head and shank guided in corresponding cylindrical parts of a through bore in the crown head and in its skirt, this skirt terminating with an inner shoulder in which part of the shank is keyed. A spring in the skirt acts against this shoulder and, in addition to outwardly biasing the push-button, compresses a further annular seal between the push-button and the skirt. The outer position of the push-button is defined by a widened terminal part of its shank abutting against said shoulder, this terminal part being secured to a winding stem.
