If the watch is left in direct sunlight for a long time, the display may become black, but this condition will be corrected when the watch returns to normal temperature. Do not leave your watch in very low temperatures below -10°C (+14°F) for a long time since the cold may cause: a. a slight time loss or gain. b. the change of digits to become slow. c. the alarm sound to become faint. d. the display light to dim. However, the above conditions will be corrected when the watch returns to normal temperature. I 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.

Keep your watch away from close contact with magnetic objects.
