Abstract
Abstract 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 flangeshaped 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 Oring, 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A fluidtight winding mechanism for a watch movement and the like comprising: a socket member having in a bottom portion thereof means defining an opening; a tubular member extending through said opening and rigidly connected to said socket member; a button movably mounted within said socket member to undergo both manual rotational movement and manual axial sliding movement and having an inner portion composed of deformable synthetic material in compressively deformed contact with said tubular member and cooperative therewith to establish a fluidtight connection Therebetween; and a driving shank extending into said tubular member and having at one end a head portion embedded in and connected to said synthetic material and connectable at the other end to a member to be wound.
Claim 2
Dependent Claim
122 words
A fluidtight winding mechanism for a watch movement and the like comprising: a socket member having in a bottom portion thereof means defining an opening; a tubular member extending through said opening and rigidly connected to said socket member; a button movably mounted within said socket member to undergo both manual rotational movement and manual axial sliding movement and having an inner portion composed of deformable synthetic material in compressively deformed contact with said tubular member and cooperative therewith to establish a fluidtight connection Therebetween; and a driving shank extending into said tubular member and having at one end a head portion embedded in and connected to said synthetic material and connectable at the other end to a member to be wound.
Claim 3
Dependent Claim
26 words
A fluidtight winding mechanism according to claim 1; including an O-ring type packing interposed between said button and said socket member establishing a fluidtight connection therebetween.
Claim 4
Dependent Claim
41 words
A fluidtight winding mechanism according to claim 1; wherein said inner portion of said synthetic material in compressively deformed contact with said tubular member includes a plurality of annular beads each encircling said tubular member and in compressively deformed contact therewith.
Claim 5
Dependent Claim
27 words
A fluidtight winding mechanism according to claim 1; including an O-ring type packing interposed between said driving shank and said tubular member establishing a fluidtight connection therebetween.
Claim 6
Dependent Claim
26 words
A fluidtight winding mechanism according to claim 4; including an O-ring type packing interposed between said button and said socket member establishing a fluidtight connection therebetween.
