This watch is a self-winding watch equipped with a manual winding mechanism.
When the watch is worn on the wrist, the motion of the wearer’s arm winds the mainspring of the watch.
When first using a stopped watch, it is recommended that you manually wind the mainspring by turning the crown.
How to manually wind the mainspring by turning the crown
-
The crown is a screw down crown. Turn the crown counterclockwise to unlock the screw. (When the screw is completely unlocked, the crown is projected outward from its original position.)
-
After unlocking the screw, slowly turn the crown clockwise to wind the main-spring. Take care not to press down the crown.
-
Wind the mainspring until the power reserve indicator shows a full-wound state. Immediately, the seconds hand starts moving.
-
Gently turn the crown clockwise while pressing it, until it is screwed all the way in and locked.
As for manual winding, if you give the crown five full rotations, it provides the power to run the watch for approximately ten hours.
If the crown is turned counterclockwise, the mainspring of the watch will not be wound.
To check the winding state of the mainspring, refer to How to read the power reserve indicator.
There is no need to turn the crown further when the mainspring is fully wound. The crown can be turned without damaging the watch mechanism; it only winds the mainspring free.
While screwing the crown in, the watch clicks as the mainspring is wound. This should not cause any concern since this is caused by movement of the mainspring.
