This fluid-tight mounting for a control member for a watch movement or like mechanism comprises a winding button having a member of synthetic material fitted therein, in which the flange-shaped head of a shank for driving the associated part is embedded. Rigid with the case of the mechanism is a socket having a bottom through which said shank extends towards the mechanism to be controlled. The socket receives in smooth frictional contact the skirt of said button with the interposition of an O-ring, thus permitting both rotational and axial sliding movements of said button therein and protecting said member of synthetic material against any attack from external agents.
