(1) Battery life
The miniature battery which powers your watch should last approximately 2 years, if a new normal battery SB-T51
(CR2032) is installed.
● If the built-in illuminating light is turned on more than three times a day, the battery life may be less than the
specifi ed period.
(2) Monitor battery
The battery in your watch may run down in less than 2 years after the date of purchase, as it is a monitor battery
which is inserted at the factory to check the function and performance of the watch.
(3) Battery change
1. For battery replacement, be sure to have the battery replaced with a new one at the retailer from whom
the watch was purchased or an SEIKO DEALER, and request the battery for exclusive use with the SEIKO
watches.
2. If the old battery is left in the watch for a long time, a malfunction may be caused due to battery leakage,
etc. Have it replaced with a new one as soon as possible.
3. Battery replacement is charged even if it runs down within the guarantee period.
4. Once the case back is opened for battery replacement or other purposes, the original water resistant qual-
ity designed for the watch may deteriorate when it is closed. When you have the battery replaced with a
new one, also request the water resistance test pertaining to the water resistant quality of your watch.
