Inside a minute repeater, a rare horological complication

This invention was born at the end of the 17th century in England, where the watchmaker Daniel Quare was the first to manufacture and patent this system in a pocket watch. Unlike other complications, it originally served a real purpose: to tell the time at night, at a time when electricity did not exist. The function of a minute repeater is to strike the hours, quarters and minutes on demand by pressing a pusher.
