The 18th-century horologist John Harrison claimed that he could make the world's most accurate pendulum clock, but his methods were scorned for hundreds of years—until someone proved him right.

It may be I just didn’t spend enough time adjusting the pendulum length–I hate to stop the pendulum and turn that little nut. I agree that at least the nicer of my two clock is very stable.

“Every clock needs two components: first, a time base generator—such as a pendulum in a pendulum clock, or even a quantum oscillation,” Marcus Huber, the senior author of the study from TU Wien, said ...

John Harrison, one of the world’s greatest clockmakers, claimed to have designed the perfect pendulum clock in the mid-18th century. Instead of being celebrated, Harrison’s plans were ...

When a pendulum clock is running properly, you should hear a rhythmic and even "TICK-TOCK." If you're hearing "tick-TOCK, tick-TOCK," your clock is not going to be running for long.

Designed 300 years ago but completed only now, this chronometer officially became “the most accurate mechanical clock with a pendulum swinging in free air”, certified by Guinness World Records.

While the clock's face might be challenging to read, and some components needed adjustments along the way, the final product is impressive and offers a fantastic prototype for future exploration.

The iconic clock tower has been running up to six seconds late. ... Errors are normally fixed by adding and removing old coins in the pendulum to adjust the rate at which it swings.
