Electronic watch with conductor tracks formed on the watch glass

Details

Inventors: Muller, Jacques; Mock, Elmar;
Assignee: ETA, S.A., Fabriques d'Ebauches (CH)
Primary Examiner: Roskoski; Bernard

Attorney, Agent or Firm: Allegretti, Newitt, Witcoff & McAndrews Ltd.

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.

DETAILED DESCRIPTION In order to overcome these disadvantages, the present invention concerns an analog or digital electronic watch in which the conductor tracks connecting the different components of the watch are formed on the inside face of the glass of the watch, the glass thus serving as an insulating carrier.
In addition, some of the components may be directly fixed on the inside face of the glass.
