PRECAUTIONS ON USING THE WATCH FOR DIVING

Before diving, make sure that the watch operates normally and be sure to observe the precautions described below.

BEFORE DIVING

● Do not use the watch for saturation diving using helium gas

- Check that:

• the crown is locked tightly in place.

- there are no visible cracks in the crystal or the watch band.

- the strap or bracelet is securely fastened to the watch case.

- the buckle keeps the strap or bracelet firmly secured to the wrist.

- the rotating bezel turns counterclockwise smoothly (the rotation must not be too loose or

too tight and the " " mark aligns with the minute hand.

- the time and calendar are appropriately set.

- the second hand is operating normally (if not, swing the watch for more than 30 seconds

to wind the mainspring sufficiently).

If there are any malfunctions, we recommend that you contact an AUTHORIZED SEIKO SERVICE CENTER.

WHILE DIVING

• Do not operate the crown when the watch is wet or in water.
  ● Take care not to hit the watch against hard objects such as rocks.
• Bezel rotation may become slightly stiffer underwater. This is not a malfunction.

AFTER DIVING

● Rinse the watch in fresh water after diving and wash out all seawater, soil, sand, etc.
● Wise the watch thoroughly dry to prevent possible rust on the case after cleaning the watch in fresh water.

SECOND HAND HALT MECHANISM (4R35/4R36)

HOW TO START THE WATCH(4R15/4R16/7S26/7S35/7S36)

This is an automatic mechanical watch.

To initially start your watch:

Swing it from side to side in a horizontal arc for about 30 seconds.

* If the watch is worn on the wrist, the mainspring will be wound automatically through normal wrist movement.

* If the watch is used without being wound up sufficiently, gain or loss of the watch may result. To avoid this, wear the watch for more than 8 hours a day.

HOW TO START THE WATCH(4R35/4R36)

This watch is an automatic watch equipped with a manual winding mechanism.

To initially start your watch:

If your watch is completely stopped, it is recommended that you manually wind the mainspring by turning the crown.

● How to manually wind the mainspring by turning the crown

1. Unlock the crown by turning it counterclockwise.
2. Slowly turn the crown clockwise to wind the mainspring.
3. Continue to turn the crown until the mainspring is sufficiently wound. The second hand will start moving.
4. Lock the crown by turning it clockwise while pressing it.

* When setting the hands, first set them to a time a few minutes earlier than the correct time, and then advance them to the exact time.
* It is necessary to adjust the date on the first day after a month that has less than 31 days.

ROTATING BEZEL

The rotating bezel can show up to 60 minutes of elapsed time.

Elapsed time

1 Turn the rotating bezel to align the "▼" mark to the minute hand.

2 When time has elapsed, read the number on the rotating bezel.

Example: Starting time : 10:10 Finishing time : 10:40 Elapsed time : 30 minutes

For safety's sake, the rotating bezel rotates only counterclockwise, so that the time measured is never shorter than the actual elapsed time.

TO PRESERVE THE QUALITY OF YOUR WATCH

■ TEMPERATURES

The key components in mechanical watches are made of metals, which expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical watches tend to lose time at high temperatures while they tend to gain time at low temperatures.

MAGNETISM

Your watch will be adversely affected by strongmagnetism. Keep it away from close contact with magnetic objects.

CHEMICALS

Be careful not to expose the watch to solvents, mercury, cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged.

■ PERIODIC CHECK

It is recommended that the watch be checked once every 2 to 3 years by an AUTHORIZED SEIKO DEALER or SER VICE CENTER to ensure that the case, crown, gasket and crystal seal remain intact.

■ CARE OF CASE AND BRACELET

To prevent possible rusting of the case and bracelet, wipe them periodically with a soft dry cloth.

Be careful not to drop your watch or hit it against hard surfaces.

■ PRECAUTION REGARDING CASE BACK PROTECTIVE FILM

If your watch has a protective film and/or a sticker on the case back, peel them off before using your watch.

LUMIBRITE™

LumiBrite is a newly developed luminous paint that is completely harmless to human beings and the natural environment, containing no noxious materials such as radioactive substances. LumiBrite absorbs the energy of sunlight or artificial light 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 5 to 8 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.

When you make a dive in dark water, LumiBrite may not emit light unless it has absorbed and stored light sufficiently.

Before diving, therefore, be sure to expose the watch to light under the conditions specified above, so that it fully absorbs and stores light energy. Otherwise, use the watch together with an underwater flashlight.
