The case back shows the caliber and performance of your watch Water resistant performance Refer to "Water resistance". page 20 9F83 Caliber Number The number to identify the type of your watch ※ The above figures are examples. Both of them may be different from the figure on the case back of your watch. Water resistance Refer to the table below for the description of each degree of water resistant performance of your watch before using. Indication on the case back No indication WATER RESISTANT WATER RESISTANT 5 BAR WATER RESISTANT 10 (20) BAR Water resistant performance Conditions of Use Non-water resistance Water resistance for everyday life Avoid drops of water or sweat The watch withstands accidental contact with water in everyday life WARNING Not suitable for swimming Water resistance for everyday life at 5 barometric pressures The watch is suitable for swimming. Water resistance for everyday life at 10 (20) barometric pressures The watch is suitable for diving not using an air cylinder. 20 English 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 40000A/m MAGNETIC RESISTANT 80000A/m The watch can maintain its performance in most cases where it is brought close to (at least 1cm spaced from) magnetic products not only in normal daily life circumstances but also in a special work environment. 40,000A/m 80,000A/m A/m (ampere meter) is the International unit (SI unit) for indicating the magnetic field. Examples of common magnetic products that may affect watches Cellular phone (speaker) AC adapter Bag AC-powered shaver (with magnet buckle) Magnetic cooking Portable radio device (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 to suppress the turn of the motor. 21
