Product Usage Instructions

Length Adjustment for Metallic Bands

If your metallic band requires length adjustment, you can visit
the retailer from whom you purchased the watch for assistance. If
you received the watch as a gift or are unable to visit the
retailer, please contact SEIKO CUSTOMER SERVICE CENTER. Some
retailers may charge for this service.

Removing Protective Film

If your watch has a protective film to prevent scratches, make
sure to peel it off before using the watch. Using the watch with
the film on may cause dirt, sweat, dust, or moisture to be trapped
and could lead to rust.

Overhaul and Inspection

We recommend requesting an overhaul for inspection and
adjustment of your diver’s watch approximately once every three to
four years. The use environment of the watch can affect not only
the case or band but also the internal mechanism. Contact SEIKO
CUSTOMER SERVICE CENTER or the retailer from whom you purchased the
watch to arrange for an overhaul.

Handling Cautions

WARNING: Please strictly observe the following safety
regulations to avoid serious consequences.

1. Corrosion or Damage: Immediately stop wearing the watch
   if the watch body or band becomes corroded or damaged. Consult the
   retailer from whom you purchased the watch or SEIKO CUSTOMER
   SERVICE CENTER for assistance.

2. Keep Out of Reach: Keep the watch and accessories out of
   the reach of babies and children to prevent accidental swallowing.
   If a baby or child swallows the battery or accessories, immediately
   consult a doctor.

3. Secondary Battery: Do not remove the secondary battery
   from the watch. Replacement of the secondary battery requires
   professional knowledge and skill. Consult the retailer from whom
   you purchased the watch for battery replacement. Using an ordinary
   silver oxide battery can cause bursting and ignition.

For more detailed instructions on using specific features of the
watch, please refer to the relevant sections in the user
manual.

Please note that there is a risk of minor injury or material damage if the following safety regulations are not strictly observed.

HOW TO USE

Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch. * If the inner surface of the glass is clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER.

Do not leave moisture, sweat and dirt on the watch for a long time.
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 wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch.

[One-Way rotating bezel] As the evaluation of the remaining air in your cylinder is based on the information of the elapsed time of the dive,

the rotating bezel for a diver’s watch is designed to rotate only counterclockwise, so that the watch is prevented

from displaying the elapsed time shorter than it actually is.

Power Source
The battery used in this watch is a special secondary battery, which is different from ordinary batteries. Unlike an ordinary silver oxide battery, the secondary battery does not require periodic replacement.
The capacity or charging efficiency may gradually lower due to long-term use or operating environment. In addition, long-term use may shorten the charge duration due to wear, contamination, lubricant deterioration of mechanical parts, etc. Request repair when the performance lowers.
b WARNING

Notes on replacing the secondary battery
· Do not remove the secondary battery from the watch. Replacement of the secondary battery requires professional knowledge and skill. Please ask the retailer from whom the watch was purchased for replacement of the secondary battery.
· Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition.

• Overcharge prevention function
  When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging. There is no need to worry about damage caused by overcharging no matter how much the secondary battery is charged in excess of the “time required for fully charging the watch.” * For the required time to fully charge the battery, see “Guide to charging times” P.38.

Notes on charging the watch

· When charging the watch, do not place the watch in close proximity to an intense light

source such as lighting equipment for photography, spotlights or incandescent lights,

as the watch may be excessively heated resulting in damage to its internal parts.

Lumibrite

If your watch has Lumibrite

Lumibrite is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses in a short

time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for

approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite

emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the

emitted light may also differ slightly depending on such factors as the brightness of the place where the

watch is exposed to light and the distance from the light source to the watch.

• In general, when coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt

to the darkness making it difficult to see objects initially. (Dark adaptation)

• Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment,

containing no toxic materials such as radioactive substances.
