CAUTIONS ON WATER RESISTANCE

CAUTIONS

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 that watch was purchased or Grang Saks International service network mentioned on CERTIFICATE OF GUARANTEE or our website.

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 water.

If water-resistant level of your watch is defined as "WATER RESISTANT"

WARNING

Do not use the watch in scuba diving or saturation diving.

NCTIONS OF DIVER'S MODEL

Unidirectional rotating bezel

By using the rotating bezel, you can measure the elapsed time since the start of an event or an activity such as diving.

The watch has a unidirectional melting bed. As the evaluation of the remaining sk in your cylinder is based on the information of the elapsed time of the olive, the rotating bevels for a diver's watch is designed to rotate only counterlockwise, so that the watch is presented from displaying the elapsed time shorter than it actually is.

CAUTION

Make sure that you check the correct remaining amount of an in your cylinder before diving. Use the display of the elapsed time by the rotating buzel only as a guide during diving.

How to use the rotating bezel

① At the start of the activity, for which you want to measure the elapsed time (for example, when you start diving), rotate the bezel so that the Ⓦ mark on the bezel is aligned with the minute hand.
② Head the graduation on the rotating bezel to which the minute hand is pointing.

[Ex.] When you start diving at 10:10.

Start of the dive Align the mark with the minute hand After 15 minutes has elapsed Rotating direction of the bazeal Read the graduation on the rotating bazeal to which the minute hand is painting.

Slide adjuster

If your watch has a metal bracelet equipped with a slide adjuster mechanism, you can easily adjust the bracelet length by yourself. This is very useful when you wear the watch over a wetsuit or a heavy winter clothing.

How to use the slide adjuster

① Lift up the flap approximately 90^ and press it down further approximately 20^ , and hold it there.
※ You may feel slight resistance, but doing this requires only a light force. Please do not push the gap down forcibly.
② Lightly pull the bracelet on the 6 o'clock side of the watch along the curved line of the bracelet.

Daily care

The watch requires good daily care

☐ Do not wash the watch when its crown is at the extended position.
☐ Wipe away moisture, sweat or dirt with a soft cloth.
After soaking the watch in seswater, be sure to wash the watch in clean pure water and wipe it dry carefully.
※ if your watch is rated as "non-water resistant" or "water resistant for daily use", do not wash the watch.
→ *CHECK THE CALIBER NUMBER AND WATER-RESISTANT LEVEL* page 3

Turn the crown from time to time

○ In order to prevent corrosion of the crown, turn the crown from time to time.

○ The same practice should be applied to a screw down crown.

⇒ "Crown" page 10.

Band

The band touches the skin directly and becomes dirty from sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage.

Metallic band

○ Moisture, sweat or soil will cause rust over on a stainless steel band if they are eff for a long time.
- Lack of care may cause a yellower or grid stain on the lower sleeve edge of shirts. - Wipe off moisture, sweat or soft with a soft cloth as soon as possible.
To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush (Protect the watch body from water splashes by wrapping it up in plastic wrap etc).
(1) Because some titanium bracelets use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts.
- If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the grasp may not open.
○ If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.

Leather band

☐ A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.

○ Wipe off moisture and sweet as soon as possible by gently plating him up with a dry bath. ○ Do not expose the watch to direct sunlight for a long time.
☐ Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
☐ Retain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when working with water even if the watch itself is water-resistant enforced for daily use.

Silicone band

As for material characteristics, the band is easily dried, and may be stained and discolored. Wipe off dirt with a wet cloth or cleaning tissue.

☐ Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool.

Notes on skin irritation and allergy

Skin irritation caused by a band has various reasons such as allergy to metals or leathers, or skin reactions against friction on dust or the band itself.

Notes on the length of the band

Adjust the band to allow a little clearance with your wrist to ensure proper airflow. When wearing the waton, leave enough room to insert a finger between the band and your wrist.

Magnetic resistance (Magnetic influence)

Affected by nearby magnetism, a watch may temporarily gain or lose time or stop operating.

Indication on the case back	Condition of use	Certified level
	Keep the watch more than 5 cm away from magnetic products.	4,800A/m
	Keep the watch more than 1 cm away from magnetic products.	16,000A/m
MAGNETIC RESISTANT 70000A/m	The watch can maintain its performance in most cases where it is brought close to tall least 100 seconds from magnetic products not only in normal daily life circumstances but also in special work environment.	40,000A/m
MAGNETIC RESISTANT 80000A/m		80,000A/m

A/m (ampere motor) is the International unit (S unit) for indicating the magnetic field.

Examples of common magnetic products that may affect watches

Cellular phone (speaker)	AC adaptor	Bag (with magnet buckle)	AC powerce shaver
Magnetic cooking device	Portable radio (speaker)	Magnetic necklace	Magnetic health pillow

If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, the watch may need to be demagnetized. In this case, you will be charged for demagnetization and accuracy readjustment even if it happens within the guarantee period.

The reason why analogue quartz watch is affected by magnetism

It is because the built-in motor of the watch, which, harnesses magnetic power and external strong magnetism, affect each other to stop the motor or suppresses the turn of the motor.

Lumibrite

If your watch has Lumibrite

Lumibrite is a luminous paint that is completely harmless to human beings and the natural environment; containing no noxious manetals such as radioactive substance. Lumibrite is a newly-developed luminous paint that absorbs light energy of the sunlight and lighting apparatus in a short time and stores it not enable 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 2 to 5 hours. Please note, however, Lumibrite ensures 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 of the light. The light worth is exposed to light and the distance from the light source to the watch.

* In general, when you enter a dark place from a bright environment, your eye cannot adapt to the change in light levels quickly. At first, you can hardly see anything, but as time passes, your vision gradually improves. (Dark adaptation of the human eye)

Reference data on the luminance

EAP SECOND

Normally there are 86,400 seconds in a day. Due to a slight change in the earth's rotation, an extra second may be added to one day during the year. This is called the leap second. Every year the decision is made whether such an adjustment is needed. When the adjustment, lakaz place, the standard time should be corrected by delaying the standard time one second. To keep your Grand Selko watch accurate with the world standard time, adjust your watch to a time signal whenever such adjustment is made. According to the information from the observations all over the world, the standard time is delivered one second as well as the World Royal Observatory. In the Great window, Mean Time, an extra second will be added to the one minute between 1:50 p.m. and 0:00 a.m., either on December 31st or on June 30th. However, the adjustment may not be made in some years. Please check a new supersup, etc. whether such an adjustment will be made or not.
