• Never leave your watch on the dashboard of a car, near a heater, or in any other location that is subject to very high temperatures. Do not leave your watch where it will be exposed to very low temperatures. Temperature extremes can cause your watch to lose or gain time, to stop, or otherwise malfunction.

• Leaving your watch in an area hotter than +60°C for long periods can lead to problems with its LCD. The LCD may become difficult to read at temperatures lower than 0°C and greater than +40°C.
