Abstract
Abstract The space required for electrical connections in small wrist watches incorporating electrical devices such as photo-electric elements or display elements is substantially reduced by the use of stressed metal members making firm contact with each other rather than conventional wiring and solder. This construction simplifies assembly of such watches and makes it easy to break and restore the electrical connections in the event that repair of such timepieces becomes necessary.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
79 words
An improved watch structure having a frame and removable electrical connection between electrical elements on a dial and a watch movement in a watch, said elements having terminals on the inner surface of said dial, a watch movement including electrical circuitry, said circuitry having terminals disposed proximate to and opposed to said elements terminals and biasing means between the outer surface of said dial and said frame establishing firm, removable contact between said elements terminals and said circuitry terminals.
Claim 2
Dependent Claim
79 words
An improved watch structure having a frame and removable electrical connection between electrical elements on a dial and a watch movement in a watch, said elements having terminals on the inner surface of said dial, a watch movement including electrical circuitry, said circuitry having terminals disposed proximate to and opposed to said elements terminals and biasing means between the outer surface of said dial and said frame establishing firm, removable contact between said elements terminals and said circuitry terminals.
Claim 3
Dependent Claim
16 words
The improved watch structure as defined in claim 1 wherein said biasing means is an elastomer.
Claim 4
Dependent Claim
17 words
The improved watch structure as defined in claim 1 wherein said biasing means is a wave plate.
Claim 5
Dependent Claim
67 words
The improved watch structure as defined in claim 1 wherein said elements are a plurality of solar cells, separate metallic films on the inner surface of said dial so disposed as to make contact with the electrodes of each cell and to connect said cells in series, two of said films constituting terminals suitably disposed for establishing firm, removable contact with said terminals of said electrical circuitry.
Claim 6
Dependent Claim
119 words
An improved watch structure having removable electrical connections between electrical elements on a non-conductive dial and a watch movement in a watch, a plurality of separate metallic films on the inner surface of said watch dial, each connected to an element terminal on the outer surface of said dial, a base plate opposed to and proximate said inner surface of said dial, two electrical circuitry terminals mounted on the surface of said base plate, said circuitry terminals being insulated from each other, and two flexible contact members making firm, removable contact between each of said element terminals and a corresponding circuitry terminal be reason of a pressure exerted by biasing means between the said plate and the said dial.
Claim 7
Dependent Claim
119 words
An improved watch structure having removable electrical connections between electrical elements on a non-conductive dial and a watch movement in a watch, a plurality of separate metallic films on the inner surface of said watch dial, each connected to an element terminal on the outer surface of said dial, a base plate opposed to and proximate said inner surface of said dial, two electrical circuitry terminals mounted on the surface of said base plate, said circuitry terminals being insulated from each other, and two flexible contact members making firm, removable contact between each of said element terminals and a corresponding circuitry terminal be reason of a pressure exerted by biasing means between the said plate and the said dial.
