Abstract
Abstract In a watertight timepiece a tubular member passes through the timepiece casing and a winding shaft passes through the tube with a tubular member and is connected to an elastically deformable winding button which is slidably mounted over an end of the tubular member in a fluidtight manner. The fluidtightness is obtained by contact between the elastically deformable winding button and the tubular member without the interposition of a fluidtight packing, the winding button having an annular inner projection in fluidtight contact with the tubular member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
In a timepiece, a fluidtight connection for a timepiece winding knob comprising: a fixedly mounted metallic tubular member connectable at one end to a timepiece casing; an elastically deformable winding knob elastically deformed around and in direct fluidtight, sliding contact with an outer peripheral portion of the other end of said tubular member, said elastically deformable winding knob comprising means defining a hollowed out interior portion enclosing said other end of said tubular member, and an annular projection extending radially inwardly from an end peripheral portion of said hollowed out interior portion in fluidtight, sliding contact with said tubular member; and a metallic core member embedded in said elastically deformable winding knob having a projecting portion extending into said other end of said tubular member, and means on said projecting portion releasably connectable to a winding staff of said timepiece.
Claim 2
Dependent Claim
140 words
In a timepiece, a fluidtight connection for a timepiece winding knob comprising: a fixedly mounted metallic tubular member connectable at one end to a timepiece casing; an elastically deformable winding knob elastically deformed around and in direct fluidtight, sliding contact with an outer peripheral portion of the other end of said tubular member, said elastically deformable winding knob comprising means defining a hollowed out interior portion enclosing said other end of said tubular member, and an annular projection extending radially inwardly from an end peripheral portion of said hollowed out interior portion in fluidtight, sliding contact with said tubular member; and a metallic core member embedded in said elastically deformable winding knob having a projecting portion extending into said other end of said tubular member, and means on said projecting portion releasably connectable to a winding staff of said timepiece.
Claim 3
Dependent Claim
33 words
A timepiece according to claim 1; further including means defining an annular groove on said other end of said tubular member dimensioned to releasably receive therein in a fluidtight manner said annular projection.
Claim 4
Dependent Claim
34 words
A timepiece according to claim 1; wherein said metallic core member includes a plurality of arms embedded in said elastically deformable winding knob effective to increase the resiliency of said elastically deformable winding knob.
Claim 5
Dependent Claim
177 words
In a timepiece, a fluidtight connection for a timepiece winding knob comprising: a fixedly mounted metallic tubular member connectable at one end to a timepiece casing; an elastically deformable winding knob elastically deformed around and in direct fluidtight, sliding contact with an outer peripheral portion of the other end of said tubular member, said elastically deformable winding knob comprising means defining a hollowed out interior portion enclosing said other end of said tubular member, and a plurality of axially spaced-apart annular projections extending radially inwardly from an end peripheral portion of said hollowed out interior portion each in fluidtight, sliding contact with said tubular member; means defining a plurality of axially spaced-apart annular grooves on said other end of said tubular member each dimensioned to releasably receive therein in a fluidtight manner one of said annular projections; and a metallic core member embedded in said elastically deformable winding knob having a projecting portion extending into said other end of said tubular member, and means on said projecting portion releasably connectable to a winding staff of said timepiece.
Claim 6
Dependent Claim
177 words
In a timepiece, a fluidtight connection for a timepiece winding knob comprising: a fixedly mounted metallic tubular member connectable at one end to a timepiece casing; an elastically deformable winding knob elastically deformed around and in direct fluidtight, sliding contact with an outer peripheral portion of the other end of said tubular member, said elastically deformable winding knob comprising means defining a hollowed out interior portion enclosing said other end of said tubular member, and a plurality of axially spaced-apart annular projections extending radially inwardly from an end peripheral portion of said hollowed out interior portion each in fluidtight, sliding contact with said tubular member; means defining a plurality of axially spaced-apart annular grooves on said other end of said tubular member each dimensioned to releasably receive therein in a fluidtight manner one of said annular projections; and a metallic core member embedded in said elastically deformable winding knob having a projecting portion extending into said other end of said tubular member, and means on said projecting portion releasably connectable to a winding staff of said timepiece.
Claim 7
Dependent Claim
34 words
A timepiece according to claim 4; wherein said metallic core member includes a plurality of arms embedded in said elastically deformable winding knob effective to increase the resiliency of said elastically deformable winding knob.
