Watch Performance and Specifications

The operating temperature range is shown below. -10℃～40℃

Do not leave the watch for long periods on the dashboard of a car, near a heater, or in any other hot location, or in a cold location. Doing so creates the risk of malfunction. Also, note that the LCD panel may be damaged if exposed to temperatures of 60°C or higher for long periods. Figures on the LCD may become difficult to see at temperatures of 0°C or lower, or +40°C or higher.

Even if ambient temperature is with the range described above, the availability of some functions may become limited if the watch's internal temperature rises due to operating conditions.
