What are "hack" seconds?

Hack Seconds

Many watches today have a "hack seconds" feature. When the crown is pulled out to adjust the time, the seconds will stop. This allows accurate synchronization with another clock. On most hack movements, when the crown is pulled out, a lever is moved which contacts the rim of the balance, which causes the movement to stop.
