The Seiko Quartz Stopwatch Cal. S064 is a stopwatch with a solar charging
function, featuring the NFC data communications function.
This watch can store up to 300 lap records. If the number of records is 300 or
less, they can be divided and stored.
The NFC data communications function enables lap records in the watch to be
transferred to a PC as data via the NFC reader (dedicated application is required).

purchased…or…SEIKO…CUSTMER…SERVICE…CENTER.
Be…aware…of…a…risk…that…a…water…resistant…watch…may…lessen…its…water…
resistant…performance…because…of…deterioration…of…the…adhesive…on…
the…glass…or…gasket,…or…the…development…of…rust…on…stainless…steel.
Do not leave moisture, sweat and dirt on the watch
for a long time.
Do not wear the watch while taking a bath or a sauna.
Steam,…soap…or…some…components…of…a…hot…spring…may…accelerate…

diving,…use…special…watches…for…diving.
Do not pour running water directly from
faucet onto the watch.
The…water…pressure…of…tap…water…from…a…faucet…is…high…

Power source
The battery used in this watch is a special secondary battery, which is totally
di󱐯erent from ordinary silver oxide batteries.
Unlike other disposable batteries such as dry-cell batteries or button cells, this
secondary battery can be used over and over again by repeating the cycles of
discharging and recharging.
However, for various reasons such as long-term use or usage conditions, the
capacity or recharging e󱐰ciency of the secondary battery may gradually deteriorate.
If the e󱐰ciency of the secondary battery decreases, have the watch repaired.
■ Remarks on replacing the secondary battery
・Do…not…remove…the…secondary…battery…yourself.
……Replacement…of…the…secondary…battery…requires…professional…
knowledge…and…skill.…Please…ask…the…retailer…from…whom…the…watch…
was…purchased…for…repair.
・…Installation…of…an…ordinary…silver…oxide…battery…can…generate…heat…that…
