How to wind the mainspring
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 normally worn on the wrist. In addition, it can be wound by turning the crown.
A stopped watch can be started by arm movement when it is worn on the wrist, however, before wearing the watch, wind the mainspring sufficiently and set the time. When winding 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.
The mainspring is sufficiently wound when the crown is turned approximately 60 times. When the mainspring is in the full-winding state, it is designed so that the mainspring slips if it is overwound. Therefore, it is not necessary to worry about breaking the mainspring, however, please refrain from excessive operation.
It is recommended that you wear the watch on your wrist more than 10 hours a day to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may lose or gain time. If you use the watch without wearing on your wrist, wind the mainspring up sufficiently by turning the crown by hand every day at a fixed time.
CAUTION
For models with a screw down crown, remember to screw the crown in.
Due to its gear train mechanism, for setting the time of the mechanical watch correctly, the hands should be set back once slightly and then set forward to the correct time.
How to set the time
-
Pull out the crown when the seconds hand is at the 12 o’clock position. (The seconds hand stops.)
-
Push the crown back in to the normal position in accordance with a time signal. The watch starts operating.
Turn the crown to set the hour and minute hands to the desired time.
