To Preserve the Quality of Your Watch ・Power source The battery used in this watch is a special secondary battery, which is different from ordinary batteries. Unlike an ordinary silver oxide battery, the secondary battery does not require periodic replacement. H owever, if the secondary battery is charged or discharged repeatedly over an extended period of time, its life may shorten（. This condition changes depending upon usage condition and storage environment.） The secondary battery is an environmentally friendly, clean energy storage device. NOTICE ・W hen replacing the secondary battery, make sure that the exclusive secondary battery for this watch is used. Installation of an ordinary silver oxide battery can generate heat that can cause bursting or ignition. ・E ven when a silver oxide battery is substituted, electrical continuity cannot be obtained. 131
