The Seiko 7T32 is a an alarm chronograph watch. It has a battery life indicator that provides notification when the battery is nearing its end. When the small second hand begins to move in 2-second intervals instead of the usual 1-second interval, this is an indication that the battery needs to be replaced. Though it is recommended that an authorised Seiko dealer be used to replace batteries for Seiko watches, with the right tools, a novice can successfully replace the Seiko 7T32 battery. Use the SR927W Seiko battery, which can be obtained at any authorised Seiko watch repair store. The SR927W Seiko battery can also be ordered online from reputable watch parts distributors such as Apex Battery. Though not recommended, non-Seiko brand batteries can be purchased at any electronics store.
