Cuckoo clock
typically pendulum-regulated clock that strikes the hours with a sound like a common cuckoo's call

A cuckoo clock is a type of clock, typically weight driven and pendulum regulated, that strikes the hours with a sound like a common cuckoo call and has an automated cuckoo bird that moves with each note. Some move their wings and open and close their beaks while leaning forwards, whereas others have only the bird's body leaning forward. The mechanism to produce the cuckoo call has been in use since the middle of the 18th century and has remained almost without variation.
It is unknown who invented the cuckoo clock and where the first one was made. It is thought that much of its development and evolution was made in the Black Forest area in southwestern Germany (in the modern state of Baden-Württemberg), the region where the cuckoo clock was popularized and from where it was exported to the rest of the world, becoming world-famous from the mid-1850s on. Today, the cuckoo clock is one of the favourite souvenirs of travellers in Germany, Switzerland, Austria and eastern France. It has become a cultural icon of Germany.
Characteristics
The design of a cuckoo clock is now conventional. Many are made in the "traditional style", which are made to hang on a wall. The classical or traditional type includes two subgroups; the carved ones, whose wooden cases are decorated with leaves, animals, etc., and a second one with cases in the shape of a chalet.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Cuckoo clock”, the useful work is to connect “typically pendulum-regulated clock that strikes the hours with a sound like a common cuckoo's call” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q155518. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
