○  When setting the time, make sure that the mainspring is sufficiently 

wound. 

①  Make sure that the mainspring is sufficiently wound and the watch is 

working.

○  This  watch  is  an  automatic  winding  type  (with  manual  winding 

function).

○  The  mainspring  can  be  sufficiently  wound  automatically  by  natural 

movement  of  the  arm  while  it  is  worn  on  the  wrist.  In  addition,  the 

mainspring can be wound by turning the crown. Please see the power 

reserve indicator to check the level of the remaining power.

○  When starting to use a stopped watch, it is recommended that you turn 

the crown to wind the mainspring. To wind the mainspring, turn the 

crown at the normal position clockwise (12 o'clock direction) slowly. If 

you turn the crown counterclockwise (6 o'clock direction), it will turn 

free. Five full rotations of the crown will provide the power to run the 

watch for approximately ten hours.

○  If you wear the watch for twelve hours per day consecutively for 3 to 5 

days, the watch will be fully wound.

※  Under a low-temperature condition (below 0ºC), always keep at least one-sixth 

of the watch power shown by the power reserve indicator.
