Abstract
Abstract A packing means for waterproofing a watch case having a non-conductive, flexible ring portion and a conductive yet flexible arm member is disclosed. The packing device is disposed in a watch case and allows for an electrical connection to be made between the watch and an external device. The ring member is made of a resilient, non-conductive, flexible material and is disposed in the watch case so as to be sandwiched between the top and bottom members thereof. At least one arm member also made of a resilient flexible material having first and second ends is coupled to the ring and extends into the center thereof. However, the arm member is conductive and electrically couples the watch (the internal components) with the external device. The arm member is coupled to the ring member such that the substantially watertight seal in the watch case is not destroyed. By the use of the instant packing means of the present invention, a substantially waterproof seal in the watch case is achieved while permitting an external device to be electrically and flexibly coupled to the watch without destruction of the waterproof seal.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
137 words
A packing means disposed in a watch for allowing an electrical connection to be made between said watch and an external device and for providing a substantially watertight seal in said watch, said packing means comprising: a first ring member made of a resilient, non-conductive flexible material, said ring member disposed in said watch so as to provide a substantially watertight seal therein; and at least one arm member made of a resilient, conductive flexible material having first and second ends, said first end coupled to said ring member within said watch, and said second end extending outwardly therefrom and coupled to electrically external device so as to electricaly couple said watch with said external device, said arm member coupled to said ring member such that said substantially watertight seal in said watch case is not destroyed.
Claim 2
Dependent Claim
137 words
A packing means disposed in a watch for allowing an electrical connection to be made between said watch and an external device and for providing a substantially watertight seal in said watch, said packing means comprising: a first ring member made of a resilient, non-conductive flexible material, said ring member disposed in said watch so as to provide a substantially watertight seal therein; and at least one arm member made of a resilient, conductive flexible material having first and second ends, said first end coupled to said ring member within said watch, and said second end extending outwardly therefrom and coupled to electrically external device so as to electricaly couple said watch with said external device, said arm member coupled to said ring member such that said substantially watertight seal in said watch case is not destroyed.

Claim 12
Dependent Claim
26 words
The packing means as defined in claim 1 wherein each said arm member has a resilient non-conductive material disposed on each side along the length thereof.
Claim 13
Dependent Claim
38 words
The packing means as defined in claim 11 wherein each said arm member has a resilient non-conductive material disposed on the top and bottom along the length thereof so as to completely encase each said arm member therein.
Claim 14
Dependent Claim
35 words
