Abstract
Abstract An electric timepiece has a metallic grid cut from a sheet of metallic material with portions of the grid utilized for connecting the electronic circuit and other portions of the grid utilized for mechanical elements of the timepiece movement. Plastic material is overmoulded on the metallic grid to support the electronic circuit. An element of the frame of movement of the timepiece is formed by a second overmoulding of the overmoulded metallic grid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A method of manufacturing an electric timepiece having a frame of movement, mechanical elements and an electronic circuit comprising: forming a metallic grid by cutting out portions of said grid from a metallic sheet; forming at least one connection element for said electronic circuit from a first portion of said grid; forming at least one mechanical element for said timepiece from a second portion of said grid; and forming a support for said electronic circuit by overmoulding plastic material on said metallic grid portions, said support including at least one open portion.
Claim 2
Independent Claim
92 words
A method of manufacturing an electric timepiece having a frame of movement, mechanical elements and an electronic circuit comprising: forming a metallic grid by cutting out portions of said grid from a metallic sheet; forming at least one connection element for said electronic circuit from a first portion of said grid; forming at least one mechanical element for said timepiece from a second portion of said grid; and forming a support for said electronic circuit by overmoulding plastic material on said metallic grid portions, said support including at least one open portion.
Claim 3
Dependent Claim
37 words
A method as claimed in claim 1 further including: forming at least one element of said frame of movement by a second overmoulding of plastic material on said support including at least part of said open portion.
Claim 4
Dependent Claim
73 words
An electronic timepiece having a frame of movement, mechanical elements, a baseplate and an electronc circuit, comprising: a metallic grid, at least a first portion of said grid forming a connecting element of said electronic circuit, at least a second portion of said grid forming mechanical element of said timepiece; said grid being overmoulded by plastic material to form a support for said electronic circuit, said support including at least one open portion.
