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.
