Abstract
Abstract An electronic watch in which the inside face of the glass 6 of the watch comprises, on its periphery, conductor deposits (10, 16, 22, 32) forming the conductor tracks of a printed circuit, the insulating substrate of which is formed by capacitor 14, the resonator 20 or the integrated circuit 18 are fixed directly on the glass. Electrical contact means (12, 28, 30, 46) form the connections between the conductor tracks and other components which are housed in the watch casing. A deposit (8) forming a masking means on the outside face of the glass hides the printed circuit and the components.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
An electronic watch comprising a casing, said casing having an electronic watch circuit positioned therewithin, the components of said circuit including at least a battery, a display system, a resonator and an integrated circuit, said casing having a glass mounted thereon, said glass having an outside face and an inside face, with the peripheral edge of said inside face serving as a mechanical support for at least one of said components, and a plurality of electrically conductive tracks formed on at least said peripheral edge for making electrical connections between said components.
Claim 2
Dependent Claim
92 words
An electronic watch comprising a casing, said casing having an electronic watch circuit positioned therewithin, the components of said circuit including at least a battery, a display system, a resonator and an integrated circuit, said casing having a glass mounted thereon, said glass having an outside face and an inside face, with the peripheral edge of said inside face serving as a mechanical support for at least one of said components, and a plurality of electrically conductive tracks formed on at least said peripheral edge for making electrical connections between said components.
Claim 3
Dependent Claim
22 words
A watch according to claim 1 further comprising on one of its faces a deposit serving to mask said electrically conductive tracks.
Claim 4
Dependent Claim
18 words
A watch according to claim 2 wherein said deposit is disposed on the outside face of the glass.
Claim 5
Dependent Claim
36 words
A watch according to claim 2 wherein said deposit is disposed on the inside face of the glass, said watch further comprising an insulating layer which is interposed between said deposit and said electrically conductive tracks.
Claim 6
Dependent Claim
25 words
A watch according to either one of claims 3 and 4 wherein said integrated circuit is also disposed on the inside face of the glass.
Claim 7
Dependent Claim
55 words
A watch according to either one of claims 3 and 4 and further comprising at least one resilient conductor pad member of which a first end is fixed to said inside face in line with the electrically conductive tracks, while the other end forms an electrical contact with one of the components of the watch.
Claim 8
Dependent Claim
49 words
A watch according to either one of claims 3 and 4 and further comprising a conducting clamp bar on which one end is fixed to said inside face in line with the electrically conductive tracks, while the other end provides an electrical contact with a component of the watch.
