Abstract
Abstract In a wrist watch comprising a pivotally mounted bracelet element housing an electric storage cell supplying a miniature bulb for illuminating the dial, the bulb is housed in a recess between two glass-retaining snap grooves in the watch case, said recess communicating with the exterior via a bore in a tubular projection on the watch case. A sheathed conducting lead connecting the bulb to the cell passes through and is constricted in said projection by ductile deformation of the metal thereof to form a watertight fit, and is likewise constricted in a similar projection on the cell casing. The bracelet element also includes contact means for closing and opening the electric circuit of the bulb.

Claim 1
Independent Claim
227 words
In a wrist watch with a dial illuminating device, comprising a watch case, a bracelet element pivotally mounted on the watch case, means in said bracelet element for housing at least one electrical storage cell, and a miniature electric bulb housed in a recess in the watch case, the combination of : said bulbreceiving recess being provided between two glass-receiving snap grooves in the watch case, said recess communicating with the exterior of the watch case through a bore of a first tubular projection of ductile metal on the watch case; a conducting lead in an insulating sheath passing through said bore of the first projection and being fluidtightly gripped therein by a deformed portion of the first projection; said bracelet element including a metallic casing for housing said at least one cell, said casing including a second tubular projection similar to said first tubular projection, said conducting lead and sheath also passing through and being gripped in the bore of the second projection by a deformed portion thereof with said conducting lead contacting a cell in said casing; and said bracelet element additionally comprising contact means for selectively closing and opening the electrical supply circuit for said bulb which includes a first grounded pole of the bulb and a second pole of the bulb connected to said conducting lead passing through said first and second projections.
Claim 2
Dependent Claim

In a wrist watch with a dial illuminating device, comprising a watch case, a bracelet element pivotally mounted on the watch case, means in said bracelet element for housing at least one electrical storage cell, and a miniature electric bulb housed in a recess in the watch case, the combination of : said bulbreceiving recess being provided between two glass-receiving snap grooves in the watch case, said recess communicating with the exterior of the watch case through a bore of a first tubular projection of ductile metal on the watch case; a conducting lead in an insulating sheath passing through said bore of the first projection and being fluidtightly gripped therein by a deformed portion of the first projection; said bracelet element including a metallic casing for housing said at least one cell, said casing including a second tubular projection similar to said first tubular projection, said conducting lead and sheath also passing through and being gripped in the bore of the second projection by a deformed portion thereof with said conducting lead contacting a cell in said casing; and said bracelet element additionally comprising contact means for selectively closing and opening the electrical supply circuit for said bulb which includes a first grounded pole of the bulb and a second pole of the bulb connected to said conducting lead passing through said first and second projections.
Claim 3
Dependent Claim
91 words
Wrist watch according to claim 1, comprising a non-magnetic metallic casing for said at least one cell, means for electrically insulating a cell in said casing from said casing, a spring blade fixed to said casing, a soft iron contact on said blade, said blade forming means for elastically urging said contact towards one pole of a cell in said casing to close said electric circuit of the bulb, and magnetic control means cooperating with said contact to selectively magnetically attract said contact away from said pole to open said circuit.
Claim 4
Dependent Claim
104 words
Wrist watch according to claim 2, in which said magnetic control means includes a central button provided with a permanent magnet normally exerting a magnetic attraction on said soft iron contact to open said bulb circuit, a push-piece surrounding said button, and an elastic return part disposed between the button and push-piece so that by pushing in the push-piece said elastic part slides on the central button and upon releasing said push-piece said elastic part returns the push-piece to its initial position driving with it the central button and thus cutting off the magnetic attraction on the soft iron contact which closes said circuit.
Claim 5
Dependent Claim
91 words
Wrist watch according to claim 1, in which said magnetic control means includes a push-piece slidably mounted on said bracelet element and a magnet disposed between the push-piece and said casing for the cell, said magnet being movable by the push-piece from a first position in which it attracts said soft iron contact thus opening said bulb circuit to a second position in which said magnetic attraction ceases and said soft iron contact is returned by the spring blade to contact said pole of said cell and close said bulb circuit.
Claim 6
Dependent Claim
68 words
Wrist watch according to claim 1, in which said contact means include a push-piece formed by a bottom cover of said casing, said bottom cover being slidable with a cell in said casing from a first position in which said cell is spaced apart from a contact fixed to said case to a second position in which said cell bears against said contact to close said bulb circuit.
