Notes on the battery
Battery life
This watch keeps operating for approximately 3 years if a new normal battery is inserted in it.
However, since the battery life is based on the following conditions: light on once for 2 seconds a day, stopwatch measurement for 1 hour a day, and alarm usage for 20 seconds a day, the battery capacity may run out before the above period if the watch functions are used more than this.
Monitor battery
The battery in your watch is a monitor battery which is inserted at the factory to check the function and performance of the watch.
Its actual life once in your possession may be less than the specified period.
Battery replacement
For battery replacement, be sure to have the battery replaced with a new one at the retailer from whom the watch was purchased, specifying a genuine SEIKO battery.
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.
Battery replacement is made at cost even if it runs down within the guarantee period.
Once the case back is opened for battery replacement or other purposes, the original water resistant quality 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.
If your watch has 10-bar or higher water resistant quality, be sure to have such test performed on the watch every time the battery is replaced.
Please note that it takes several days to check the water resistant quality of your watch. When requesting the checking, therefore, please confirm the period required for it.
Battery life indicator
The watch is equipped with a battery life indicator that enables you to know when the battery needs to be replaced.
When the battery end of life warning icon lights up, the watch may stop within 2 to 3 days. Please ask the retailer from whom the watch was purchased to replace the battery as soon as possible.
