[. . . ] FUNCTIONS OF SOLAR POWERED WATCH These functions are only found in the solar power watch. If the watch becomes insufficiently charged, a warning comes into operation and the display changes, as below. 4. SETTING THE TIME AND CALENDAR Quick Start Feature The watch will stop if it is completely discharged. (However, the time it takes to start may vary according to the brightness of the light. ) Please note that if the light is blocked the watch might stop again as a result of being insufficiently recharged. [. . . ] (eg) Charging the watch near a light source that easily becomes hot, such as an incandescent lamp or a halogen lamp. When you charge the watch by an incandescent lamp, take a distance about 50cm from the light source to prevent extremely high temperature. TIME REQUIRED FOR CHARGE Time required for recharge may vary according to the design (colour of the dial, etc. ) and operating environment. *The recharging time is the time when the watch is continuously exposed to radiation. 10. USING FOR DIVER'S WATCHES Using the register ring Elapsed time measurement Adjust the triangle mark ( ) to the current minute indication when you start diving. You can easily read the elapsed time on the scale of the register ring while diving. Example The figure shows 10 minutes have elapsed after the dive began. Calculating the remaining time Align the register ring zero mark ( ) with the target time and use the ring's calibrations to calculate the remaining time. Screw locked crown This product is equipped with a screw lock crown to avoid water penetration and damage to the mechanism of the watch. Confirm that the crown is tightly locked for daily use and for diving. Check points at the diving site Before the dive · If the crown is tightly locked. · If there are any scratches or cracks on the wrist band or on the glass. (Normally it is possible to rotate it only in a counter clockwise direction) · If the time and date settings are correct. Recharge the secondary battery if the second hand does not advance in 1 second interval movement. · Be careful not to hit a rock or hard material with the watch. After the dive · Wash the watch with fresh water with the crown tightly locked. · Do not allow chemicals to touch the water. Full recharging time. . . . The time from when watch (Empty to full) stopped to when it is fully recharged. One day usage. . . . . . . . . . The recharging time required for the watch to run for one day. No decompression limits No decompression limits When a diver has completed a dive, and is ascending to the surface, the speed at which a diver can ascend to a surface, without stopping for decompression, is decided according to the diving depth and diving time. These limits are marked as no decompression limits which are on the watchband, are based on the U. S. (These are some models on which this is not printed. ) How to read no decompression limits DEPTH m N. D.

[. . . ] Metal watch bands should be washed periodically to keep them looking beautiful at all times. Metal watchbands are usually washed with a brush in mild, soapy water and well wiped with a soft, absorbent cloth to make sure all water is removed. Pay attention to prevent any water from getting inside your watch when the band is washed. 7. Periodic inspection Getting your watch checked once in two or three years is recommended to ensure long use and trouble-free operation. [. . . ]
