This watch has a rechargeable cell which is charged by
exposing the dial to light, such as direct sunlight or fluorescent
lamps (refer to pages
16
and
17
for charging guidelines).
After taking off the watch, put it in a location where the dial is
exposed to bright light, such as by a window.
For optimal performance, be sure to:
•
Expose it to direct sunlight for 5 or 6 hours at least once a
month.
•
Avoid leaving it in dark places for long periods of time.
CAUTION
• Donotchargethewatchathightemperature(about60°C(140°F)or higher).

When the watch reaches a low charge state (insufficient charge warning
function)
When the power reserve becomes low, the second hand
moves once every two seconds. This is the insufficient charge
warning function. Be sure to fully charge your watch as
outlined on pages
16
and
17
.
•When the watch is sufficiently charged, the second hand will
move normally.
•If you do not charge the watch for 4 days or longer after the
insufficient charge warning movement has begun, the watch will be depleted of
all power and stop.

About storing the maximum water depth
The maximum water depth hand indicates the maximum diving depth of each
measurement.
The maximum water depth is ready to be stored when either of the following
conditions is met and the stored record can be indicated after finishing
measurement:
•Water depth indication remains deeper than 1 m for 3 minutes or more in a
measurement.
•Water depth indication remains deeper than 8 m for 1 minutes or more in a
measurement.
About the record
•When a new record is stored, the previous record is overwritten.
•No maximum water depth is stored when measurement was interrupted because
of sudden change of depth (→ page
33
) or other reasons.

<Replacement of Rechargeable Cell>
•Thiswatchutilizesaspecialrechargeablecellthatdoesnotrequireperiodicalreplacement.
However power consumption may increase after using the watch for a number of years due
to wear of internal components and deterioration of oils. This may cause stored power to be
depleted at a faster rate. For optimal performance, we recommend having your watch inspected
every 2-3 years for proper operation and condition check.
WARNING
Handling of Rechargeable Cell
•Therechargeablecellshouldneverberemovedfromthewatch.
If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep out
of the reach of children to prevent accidental swallowing.
If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
•Donotdisposeoftherechargeablecellwithordinarygarbage.Pleasefollowtheinstructionsof
your municipality regarding collection of batteries to prevent the risk of fire or environmental
contamination.

WARNING
Use Only the Specified Battery
•Neveruseabatteryotherthantherechargeablecellspecifiedforuseinthiswatch.
Although the watch structure is designed so that it will not operate when another type of
battery is installed, if a conventional watch battery or other type of battery is installed in the
watch and the watch is recharged, there is the risk of overcharging which may cause the battery
to rupture.
This can cause damage to the watch and injury to the wearer.
When replacing the rechargeable cell, always make sure to use the designated rechargeable cell.
