Power reserve refers to the amount of time a mechanical watch can continue running after it has been fully wound.

The exact duration depends on the movement used in the watch. Common power reserves range from approximately 38 to 42 hours.

When the stored energy is depleted, the watch will stop and must be wound again or worn to rebuild the power reserve.

Factors such as wearing habits, activity level, and movement design can influence how effectively the power reserve is maintained during daily use.

The power reserve specification for each model can be found on the product page or in the technical documentation.
