Power reserve

  • Ben 

Power reserve refers to the duration for which a mechanical timepiece can operate autonomously after being fully wound. It indicates the amount of stored energy within the watch’s mainspring or power source. Expressed in hours or days, the power reserve serves as a crucial indicator of the watch’s functionality and reliability.

A longer power reserve signifies a timepiece that can continue to keep accurate time without requiring frequent winding or manual intervention. Luxury watches often feature power reserve indicators, typically displayed on the dial or through a subdial, allowing wearers to monitor the remaining energy and ensure timely winding or usage. By offering an extended power reserve, watchmakers demonstrate their commitment to precision and convenience, enabling enthusiasts to enjoy the uninterrupted beauty and accuracy of their cherished timepiece.
