Abstract
Abstract A jointed electronic watch comprises a plurality of watch cases each capable of bearing a different type of display and an energy source. Between the back covers (4, 5, 6) and case bands of each case are sandwiched seals (9, 10, 11) which are coupled together by isthmuses (12) at the line of articulation of the back covers and which are formed as a single piece. Within the isthmuses are arranged electrical conductors adapted to couple together the various electronic components within the plurality of cases.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band and a seal located between the back cover and the case-band wherein the seals are coupled together at the line of articulation by an isthmus formed of the same material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, electrical conductors being located within the isthmus thereby to assure a sealed passage for electric connections between the watch-cases.
Claim 2
Dependent Claim
93 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band and a seal located between the back cover and the case-band wherein the seals are coupled together at the line of articulation by an isthmus formed of the same material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, electrical conductors being located within the isthmus thereby to assure a sealed passage for electric connections between the watch-cases.
Claim 3
Dependent Claim
29 words
A jointed electronic watch as set forth in claim 1 wherein a tunnel is arranged within the isthmus adapted to accomodate a flexible printed circuit bearing said electrical connections.
Claim 4
Dependent Claim
26 words
A jointed electronic watch as set forth in claim 1 wherein the electrical connections are held within the isthmus by overmolding of material constituting the seal.
Claim 5
Dependent Claim
59 words
A jointed electronic watch as set forth in claim 1 wherein three cases are provided each including a seal arranged between the back cover and case-band and two isthmuses coupling the respective lines of articulation, the central case bearing analog display means, a first lateral case bearing digital display means and the second lateral case bearing an energy source.
Claim 6
Dependent Claim
43 words
A method of manufacture of the watch as set forth in claim 1 comprising the step of molding in a single operation the seals and the isthmus joining them so as to form the moisture and dust blocking seal as a single piece.
Claim 7
Dependent Claim
86 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band, and a seal located between the back cover and the case-band wherein the seals are coupled together at the line of articulation by an isthmus formed of the same material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, said isthmus having a tunnel for receiving electrical conductors between the watch-cases.
Claim 8
Dependent Claim
86 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band, and a seal located between the back cover and the case-band wherein the seals are coupled together at the line of articulation by an isthmus formed of the same material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, said isthmus having a tunnel for receiving electrical conductors between the watch-cases.
Claim 9
Dependent Claim
28 words
A jointed electronic watch as set forth in claim 6 wherein said tunnel within said isthmus is adapted to accommodate a flexible printed circuit bearing said electrical conductors.
Claim 10
Dependent Claim
98 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band, and a seal located between the back cover and the case-band wherein the seals are nonconductive and are coupled together at the line of articulation by an isthmus formed of the same nonconductive material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, electrical conductors being located within the isthmus thereby to assure a sealed passage for electric connections between the watch cases.
Claim 11
Dependent Claim
98 words
A jointed electronic watch comprising at least two watch-cases coupled together by an articulation, each of said cases comprising a back cover, a case-band, and a seal located between the back cover and the case-band wherein the seals are nonconductive and are coupled together at the line of articulation by an isthmus formed of the same nonconductive material as the seals and being integrated therewith so as to form a moisture and dust blocking seal in one piece, electrical conductors being located within the isthmus thereby to assure a sealed passage for electric connections between the watch cases.
