The older Hague clocks of the 17th century, of which only a few examples are known, contain a small rectangular movement, controlled by a short pendulum and verge escapement. The movement is attached to the brass-hinged dial front panel in a simple, rectangular case which could by hung on the wall from two hooks. On the dial panel, the front of which is covered with velvet, is mounted a pierced chapter ring. Beneath the chapter ring, suspended from two hooks, is a little signature plate covering an aperture through which it is possible to reach the pendulum. Both the chapter ring and the signature shield are in silver. In later examples the hour numerals are engraved, while the hinged shield disappears; the clock is also equipped with a striking mechanism. The case has little bun feet, and a domed top to hide the bell. The back panel of the Hague clock, unlike that of the French religieuse cannot be opened, and often has a star figure in rosewood inlaid inside. The movement and the striking mechanism were originally driven from the same spring barrel, but separate barrels were introduced c. 1685. Sometimes there is also an alarm, which was originally situated in the upper part of the case against the back panel, though in later examples it is next to the movement on the front plate. Hague clocks are now extremely rare and therefore valuable.
