The mechanism to produce the cuckoo call has been in use since the middle of the 18th century and has remained almost without variation until the present.It is unknown who invented it and where the first one was made.Uniquely, quartz cuckoo clocks often include a sensor, so that when the lights are turned off at night they automatically silence the hourly chime.Other quartz cuckoo clocks are pre-programmed not to strike between a set of pre-determined hours.During the call the double doors open and the cuckoo emerges as usual, but only on the full hour, and they do not have a gong wire chime.The movement of the cuckoo in such clocks is regulated by an electromagnet that pulses on and off, attracting a weight, that acts as a fulcrum, connected to the tail of the plastic cuckoo bird, thus moving the bird up and down in his enclosure.
On the other hand, in 1669 Domenico Martinelli, in his handbook on elementary clocks Horologi Elementari, suggests using the call of the cuckoo to indicate the hours.
Starting at that time the mechanism of the cuckoo clock was known.
Any mechanic or clockmaker, who could read Latin or Italian, knew after reading the books that it was feasible to have the cuckoo announce the hours.
It is thought that much of its development and evolution was made in the Black Forest area in southwestern Germany (State of Baden-Württemberg), the region where the cuckoo clock was popularized.
The cuckoo clocks were exported to the rest of the world from the mid 1850s on. Most are made in the "traditional style" (also known as "carved") or "chalet" to hang on a wall.
