Abstract
Abstract An electronic watch with a body surrounded by a metallic ring. The ring is elastically deformable in at least some locations. Electrical contact blocks are positioned opposite the deformable portions of the ring. Pushers are operable on the ring to deform the same into contact with the blades to control functions thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
An electronic watch of the solid state type with no movable mechanical elements excepting the control elements which are manually operable to control the functions of the watch, said watch comprising, a body retaining all of the electrical components of the watch including the display devices thereof, said electrical components being completely surrounded with insulating material to render the watch humidity resistant, a metallic ring surrounding said body, said ring being elastically deformable at least at some locations thereon, said ring being maintained on the greatest portion of its height at a distance from said body, electrical contact blocks connected with electrical components within the body, said blocks being carried by the body at a location opposite the deformable portions of the ring, the ring being connected to ground of the watch, whereby exertion of a radial force on the ring at a location opposite one or the other of said blocks will deform the ring to cause the same to contact a block and ground the ring to control a function of the watch.
Claim 2
Dependent Claim
175 words
An electronic watch of the solid state type with no movable mechanical elements excepting the control elements which are manually operable to control the functions of the watch, said watch comprising, a body retaining all of the electrical components of the watch including the display devices thereof, said electrical components being completely surrounded with insulating material to render the watch humidity resistant, a metallic ring surrounding said body, said ring being elastically deformable at least at some locations thereon, said ring being maintained on the greatest portion of its height at a distance from said body, electrical contact blocks connected with electrical components within the body, said blocks being carried by the body at a location opposite the deformable portions of the ring, the ring being connected to ground of the watch, whereby exertion of a radial force on the ring at a location opposite one or the other of said blocks will deform the ring to cause the same to contact a block and ground the ring to control a function of the watch.
Claim 3
Dependent Claim
43 words
An electronic watch as claimed in claim 1 including a support in the shape of a cap constructed of insulating materials, said electrical components being disposed within said support, and an electrically insulating gel molded within the cap completely embedding said electrical components.
Claim 4
Dependent Claim
63 words
An electronic watch as claimed in claim 2 in which the cap has an outer lateral face of generally cylindrical configuration, the base of the cap having a shoulder, said contact ring being of generally cylindrical configuration and engaged on said shoulder, there being an annular free space between the outer lateral face of the cap and the inner face of the ring.
Claim 5
Dependent Claim
58 words
An electronic watch as claimed in claim 3 including a casing, pushers carried by the casing and positioned opposite selected points of said ring, said cap being positioned in the casing, said pushers being positioned opposite the contact blocks, whereby exertion of a force against a pusher causes the ring to deform and make contact with a block.
Claim 6
Dependent Claim
27 words
An electronic watch as claimed in claim 4 in which the ring includes tongues cut therefrom, said tongues being elastically deformable upon exertion of a force thereagainst.
Claim 7
Dependent Claim
20 words
An electronic watch as claimed in claim 4 in which said ring acts as a return spring for the pushers.
Claim 8
Dependent Claim
17 words
An electronic watch as claimed in claim 1 in which said ring acts as a mounting ring.
