*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.
