This watch is an automatic winding type (with manual winding function).
When the watch is worn on the wrist, the motion of the wearer’s arm winds the mainspring to operate the watch.
You can also manually wind the mainspring by turning the crown.
Guide for winding state of the mainspring
Automatic winding:
The mainspring of the watch becomes fully wound when the watch is worn for twelve hours per day for three to five consecutive days.
Manual winding:
Five full rotations of the crown will provide the power to run the watch for approximately ten hours.
Observe the power reserve indicator to check the level of the remaining power.
Power reserve indicator
Under a low-temperature condition (below 0 °C), always keep at least one-sixth of the watch power shown by the power reserve indicator.
The watch may stop.
How to manually wind the mainspring
-
Turn the crown at the normal position clockwise (12 o’clock direction) slowly.
-
Wind the mainspring until the power reserve indicator shows a fully wound state.
-
Make sure that the seconds hand is moving.
(If the watch is equipped with the screw down crown, unscrew the crown before pulling it out.)
(If the crown of your watch is a screw lock type, lock the crown.)
The crown can be turned further when the mainspring is fully wound.
Turning the crown after the mainspring is fully wound will not damage the watch, however, please refrain from excessive operation because the mainspring cannot be wound any further.
