Power reserve indicator

The power reserve indicator lets you know the winding state of the mainspring.

Before removing the watch from your wrist, observe the power reserve indicator to check if the watch has stored enough power to keep running until the next time you wear it. If necessary, wind the mainspring.
(To prevent the watch from stopping, wind the mainspring to store the excess power that will allow the watch to run for extra time.)

The orientation and design of the display may vary depending on the model.

How to read the power reserve indicator

Power reserve indicator
Winding state of the mainspring	Fully wound	Half wound	Unwound
Number of hours the watch can run	Approximately 84 hours (3.5 days)	Approximately 48 hours (2 days)	The watch either stops or is running down.

This watch is configured so that the spring cannot be over-wound.

When the mainspring is wound 50 times and becomes fully wound, the crown cannot be turned further to prevent overwinding of the mainspring. Do not try to forcefully turn the crown as this may damage the watch.

To wind 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.
