The average rate is estimated in a condition when the watch is worn on your wrist within a temperature range between 5°C and 35°C.
Under a low-temperature condition (below 0°C), always keep at least one-fifth of the watch power shown by the power reserve indicator.
When the power reserve indicator shows the power supplied by the mainspring is full, continuous operating time may be shortened depending on the how the product is used.
The specifications are subject to change without prior notice due to product improvement.
