How to Wind the Mainspring
Manual Winding
Turn the crown to wind up the mainspring.
Slowly turn the crown clockwise in its normal position (0 click).
TIP
- The crown spins freely if it is turned in the opposite direction.
CAUTION
The crown will no longer rotate when the mainspring is fully wound up.
Forcibly turning the crown may break the mainspring or damage other parts.
Use the scale marks on the power reserve indicator as a guide when winding.
