When the watch is worn on the wrist, the motion of your arm automatically winds the mainspring of the watch. Observe the power reserve indicator to check the amount of the remaining power. "POWER RESERVE INDICATOR" page 68 When first using the stopped watch, it is recommended that you manually wind the mainspring by turning the crown. How to manually wind the mainspring by turning the crown Unlock the crown. "Screw lock type crown" page 61 66 Guide for winding state of the mainspring Self-windingThe mainspring of the watch is designed to be fully wound when it is worn for twelve hours per day for three to five consecutive days. Manual windingFive full rotations of the crown will provide the power to run the watch for approximately ten hours. CAUTION The watch employs a device to prevent overwinding of the mainspring. Once the mainspring is fully wound, the mainspring slips inside, disengaging the winding mechanism. When this happens, you can still turn the crown without damaging the watch, however, please refrain from excessive operation of the mainspring. Slowly turn the crown clockwiseupwardto wind the mainspring with extra care not to press it in. Wind the mainspring until the power reserve indicator shows a full-wound state. 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. Reference data on the luminance Environment Sunlight Indoor Fine weather Fine weather Rainy weather 1m 3m 4m 78 Indication of brightnessluminance 100, 000 lux more than 3, 000 lux less than 1, 000 lux 1, 000 lux 500 luxaverage room luminance 250 lux Cloudy weather 10, 000 lux Cloudy weather 1, 000 to 3, 000 lux 79 Caliber Number The number to identify the type of your watch Magnetic resistance Refer to pages 80 and 81.

Magnetic resistanceaffect of magnetic field Grand Seiko Diver's watches conform to the Magnetic Resistance Standard of JIS Class 1. The watch has magnetic resistance to maintain performance in most cases even where it is brought close toat least 5cm spaced fromequipment generating a magnetic field in normal life. However, the movement parts are magnetized when they encounter a strong magnetic field, thereby accuracy may go out of order. Pay attention so as not to bring the watch close to equipments generating a strong magnetic field within 5cm. Magnetized items that may affect watches Examples of common items that generate a magnetic field 80 Classification of JIS antimagnetic watches Class 1 Certified level of magnetic resistance 4800A/m Indication of antimagnetism on the case back Antimagnetic quality The watch has magnetic resistance to maintain performance in most cases where it is brought close toat least 5cm spaced fromequipment generating a magnetic field in normal life. Magnetic clips Magnetic accessories Speaker of audio instruments, radios, earphones, or mobile phone etc. 81 If the accuracy exceeds the accuracy target range ± 15 seconds/monthduring normal usage due to magnetization, removal of magnetism and accuracy readjustment works are charged regardless of the guarantee period. Caution Keep the watch more than 5 cm away from magnetized products. Magnetic health equipments such as magnetic Magnetic door seal of plasters, magnetic pillows, magnetic back belts etc. refrigerator or furniture Magnetic buckle of handbags or purses Band The band touches the skin directly and becomes dirty with 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. Polyurethane band A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity. Especially a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears or discoloration. [. . . ] We recommend that you have your watch inspected and adjusted by disassembly and cleaning overhaul regularly once every 3 to 4 years.
