*1：The average rate is estimated in a condition when the watch is worn on your wrist within a temperature range between 5ºC and 35ºC.

*2：Under a low-temperature condition (below 0ºC), always keep at least one-sixth of the watch power shown by the power reserve indicator.

*3：When the power reserve indicator shows the power supplied by the mainspring is full, the continuous operating time may become shorter depending on the condition of use.
