Hacking seconds, also known as "hack seconds," is a feature that allows the seconds hand to be stopped or "hacked" when the crown is pulled out to set the time. When the crown is in the time-setting position, the hacking seconds mechanism is engaged, causing the seconds hand to stop moving. .....................................................................................................................

This feature enables precise time synchronization and facilitates accurate watch adjustment. Once the time is set, pushing the crown back in activates the movement, and the seconds hand starts moving again from the exact position where it was stopped. The hacking seconds function is commonly found in mechanical watches.
