Sealed control arrangement for a timepiece

A sealed control arrangement for a timepiece, said sealed control arrangement being lodged in a case and including a crown rotatable about a tube projecting from said case, a stem extending into said tube, said stem being movable between at least two axial positions including a neutral pushed-in position and an active drawn-out position, said crown comprising a head integrally formed with a central cylindrical portion that is fastened to said stem, said head being integrally formed with a lateral skirt concentric with said central cylindrical portion and outwardly spaced therefrom so as to form an annular housing between said central cylindrical portion and an internal wall of said skirt, said internal wall exhibiting a cylindrical wall surface having a constant diameter over its entire height, said annular housing being shaped to receive said tube;

• a packing in the form of an annular bandage compressed between said tube and said internal wall, said packing having an external portion shaped such that a lower edge of said internal wall of said skirt is always in contact with said external portion of said packing regardless of the axial position of said stem, said tube having an annular groove and said packing having an annular projection on an internal portion thereof which penetrates into said annular groove to prevent movement of said packing relative to said tube as said stem is moved.
