How to wind the mainspring
This watch is a manual winding type.
In order to wind it up completely, please refer to the following table;

About 54 turns of the crown will wind up the watch fully. |

Please see the power reserve indicator to check the level of the remaining power.
Power reserve indicator (9SA4)
From the state of the mainspring being sufficiently wound, it continuously operates for approximately 80 hours or more.
If the mainspring is not wound up sufficiently, the watch may lose or gain time. To attain a high accuracy, we suggest that the mainspring is wound so that the power reserve indicator shows a fully wound state once a day at a fixed time.
This watch is configured so that when the crown is turned and the mainspring becomes fully wound, the mainspring cannot be wound further. Refrain from forcefully winding the mainspring as this may damage the watch.
When the watch is used from a state in which the mainspring is unwound to a stop, it does not move initially even after the mainspring is wound with the winding crown. This is because of the mechanical watch’s feature that the mainspring torque (force) is weak at the beginning of mainspring winding. The seconds hand starts moving when the mainspring is wound to reach a certain degree of torque strength, while the watch can be made to move quickly by shaking it to rotate the balance wheel forcibly.
Do not pull out the crown.
Slowly turn the crown clockwise (12 o’clock direction) to wind the mainspring.
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.
