+60°C -10°C NS s TEMPERATURES Your watch works with stable accuracy between a temperature range of 5°C and 35°C (41°F and 95°F). Temperatures over 60°C (140°F) may cause battery leakage or shorten the battery life. Do not leave your watch in very low temperatures below - 10°C (+14°F) for a long time since the cold may cause a slight time loss or gain. However, the above conditions will be corrected when the watch returns to normal temperature. s SHOCKS & VIBRATION Light activities will not affect your watch, but be careful not to drop your watch or hit it against hard surfaces, as this may cause damage. s MAGNETISM Your watch will be adversely affected by strong magnetism. Keep it away from close contact with magnetic objects. s CHEMICALS Be careful not to expose the watch to solvents (e.g., alcohol and gasoline), mercury (i.e., from a broken thermometer), cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged. s CARE OF CASE AND BRACELET To prevent possible rusting of the case and bracelet caused by dust, moisture and perspiration, wipe them periodically with a soft dry cloth. s PRECAUTION REGARDING CASE BACK PROTECTIVE FILM If your watch has a protective film and/or a sticker on the case back, be sure to peel them off before using your watch.
