6R15_E.indd 4 WATCH & If the watch is completely stopped, manually turn the crown approximately 20 times to wind up the mainspring to Start the watch. & While loss/gain of a quartz watch is indicated by a monthly or annual rate, ac- curacy of a mechanical watch is normally indicated by a daily rate (loss/gain per day). # Normal usage accuracy of a mechanical watch varies according to conditions of use (time period that the watch is worn on the wrist, temperature environment, hand movement, and winding state of the mainspring). & When the watch is affected by strong magnetism, it temporarily gains or loses time. If the watch encounters a strong magnetic field, the parts of the watch may be magnetized. In this case, repairs such as removal of magnetism are required.

The crown of your watch is the screw lock type. The crown turns. Turn the crown clockwise. || The crown does not turn. Unserew the erown by turning it counterclockwise. Go to “HOW TO USE"

If your watch has a screw-lock crown, the crown will screw into the watch case for added protection. After completing all settings of the watch, screw the crown in again by turn- ing it clockwise while pressing If the crown turns out to be too stiff to be screwed in, turn the crown coun- terclockwise once and then give another try. Do not screw it in by force as it may damage the slots of the crown.

This watch is an automatic watch equipped with a manual winding mechanism. œ + When the watch is worn on the wrist, the motion of the wearer's arm winds the € mainspring of the 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. Slowly turn the crown clockwise (in the

12 o'ciock direction) to wind the main- spring.

• Tuming the crown counterclockwise (the 6 o'clock direction) does not wind the mainspring.

2. Continue to turn the crown until the main-

spring is sufficiently wound. The second hand will start moving.

3. Set the time and date before putting the

watch on your wrist.

6R15_E.indd 8 English There is no need to turn the crown further when the mainspring is fully wound. But the crown can be turned without damaging the watch mechanism. Once the watch is wound up full, it operates for about 50 hours. If the watch is used without being wound up fully, gain or loss of the watch may result. To avoid this, wear the watch for more than 10 hours à day. lf the watch is used without wearing on the wrist (if it is used on the desk like à clock, for exam- ple), be sure to wind it up fully every day at a fixed time. If the watch has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. This is because the main- spring torque (force) is low at the beginning of its winding due to the characteristics of mechanical watches. The second hand starts to move when à certain degree of strong torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to foraibly turn the balance can start the watch sooner.

6R15_E.indd 9 HOW TO SET THE TIME AND DATE Check that the watch is operating, and then set the time and date. + The watch is provided with a date function and is so designed that the date changes once every 24 hours. The date changes around 12 o'clock midnight. If AM/PM is not properly set, the date will change around 12 o‘clock noon. st click.

2. The date can be set by tuning the crown counterclock-

wise. Turn it until the previous days date appears. Ex.) Iftoday is the 6th of the month, first set the date to "5" by turning the crown counterclockwise. + Do not set the date between 10:00 p.m. and 1:00 a.m. If you do, the date may not change properly / it may cause a malfunction: Us1fBu3

3. Pull out the crown to the second click when the second hand is at the 12 o'clock

position. (The second hand stops on the spot.) Turn the crown to advance the hands until the date changes to the next. The time is now set for the a.m. period. Advance the hands to set the correct time.

4. Push the crown back in to the normal posi

The case and band touch the skin directly. Keep the case and band clean at all times. This will help to extend the life of the watch and will reduce the risk of sl ations. When you take the watch off, wipe off moisture, sweat or soil with a soft dry cloth as soon as possible. This will help to extend the life of the case, band and gasket. English <Leather strap> + Gently blot up the moisture using a soft dry cloth. Do not rub the leather, as this may cause abrasions or discoloration. <Metal bracelet> To keep the bracelet clean, use a soft toothbrush dipped in clean or soapy water. Be careful not to get water on the case. 6R15_E.indd 12 07.8.22 1:04:46 PI

Adjust the band to allow a little clearance around your wrist to ensure proper airflow. Prolonged and/or repeated contact with the band may cause skin irrita- tion_or dermatitis for those susceptible. Possible causes of dermatitis + Allergic reaction to metals or leathers + Rust, contamination or perspiration accumulated on the watch case or band. If you should develop any allergie symptoms or skin i ately stop wearing the watch and seek medical attention. WATER RESISTANCE # Non-water resistance I "WATER RESISTANT” is not inscribed on the case back, your watch is not water resistant, and care should be taken not to get it wet as water may damage the movement.

We recommend that you wear a SEIKO Divers watch wh scuba diving. Before using a water resistant 5, 10, 15 or 20 bar watch in water, make sure the crown is pushed in completely. Do not operate the crown when the watch is wet or in water. If used in sea water, rinse the watch in fresh water and dry it completely.

6R15_E.indd 15 + When taking a shower while wearing a water resistant 5 bar watch, or tak- ing a bath while wearing a water resistant 10, 15 or 20 bar watch, make sure to observe the following: + Do not operate the crown when the watch is wet with soapy water or shampoo. + Ifthe watch is left in warm water, a slight time loss or gain may be caused. This condition, however, will be corrected when the watch re- turns to normal temperature. NOTE: Pressure in bar is a test pressure and should not be considered as corre- sponding to an actual diving depth since swimming movements tend to in- crease the pressure at a given depth. Care should also be taken when diving with the watch into water.

PRECAUTIONS ON WEARING YOUR WATCH

+ Exercise care when you hold an infant or small child while wearing the watch on your wrist, as the infant or child may be injured or develop an allergic reaction caused by direct contact with the watch. + Avoid undue shocks such as dropping or scratching against hard surfaces or playing active sports, which may cause temporary malfunctions. + There is a possibility of injury caused by wearing the watch on your wrist especially if you fall down or bump into other people or objects.

ACCURACY OF MECHANICAL WATCHES

& The accuracy of mechanical watches is indicated by the daily rates of one week or so. & The accuracy of mechanical watches may not fall within the specified range of time accuracy because of loss/gain changes due to the conditions of use, such as the length of time during which the watch is worn on the wrist, arm movement, whether the mainspring is wound up fully or not, etc. & 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. & In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed of the gears. The driving force of the mainspring that powers mechanical watches varies between when it is fully wound and im- mediately before it is unwound. As the mainspring unwinds, the force weakens. Relatively steady accuracy can be obtained by wearing the watch on the wrist fre- quently for the self-winding type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up mechanical type. & When affected by external strong magnetism, a mechanical watch may loss/gain time temporarily. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair, including demagnetizing. Us1fBu3
