What is flying pendulum clock?

A flying pendulum clock, also known as a "gravity escapement clock", is a type of clock mechanism that has a pendulum that appears to float in mid-air or "fly" instead of being attached to the clock's mechanism. The concept was developed in the 17th century by Dutch mathematician Christiaan Huygens and was further refined by other clockmakers.

The flying pendulum clock uses a "gravity escapement" mechanism that allows the clock to keep accurate time by regulating the speed and movement of the pendulum. This is achieved by using a pair of curved arms or pallets to catch and release the pendulum's weight at regular intervals.

Unlike traditional pendulum clocks, the flying pendulum clock doesn't rely on friction or mechanical connections to the clock's gears, making it more accurate and reliable. However, these clocks can be quite intricate and complex to build, requiring a high level of precision and craftsmanship.

Flying pendulum clocks are considered a rare and valuable type of clock, and some antique examples can fetch high prices at auctions and collectors' markets.
