Mechanical Clocks facts

While investigating facts about Mechanical Clocks For Sale Uk and Mechanical Clocks Invented, I found out little known, but curios details like:

In the 18th century John Harrison claimed that he could build a clock to keep time to within a second over 100 days; it triggered widespread ridicule at his time. The clock had been built to his exact specifications in 2015; it was declared the "most accurate mechanical clock"

how mechanical clocks work?

The hourglass is only 700 years old, and came into use at almost exactly the same time as the first mechanical clocks.

What were mechanical clocks used for?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what are mechanical clocks. Here are 37 of the best facts about Mechanical Clocks In The Middle Ages and Mechanical Clocks History I managed to collect.

what are mechanical clocks made of?

The Atmos clock, a mechanical torsion pendulum clock which gets the energy it needs to run from temperature and air pressure changes in the environment, and can run for many years without human intervention. A temperature variation of only 1 degree is sufficient for two days operation.
The reason the snooze on a clock is 9 minutes is because in the 1950s, they had to make snooze gears fit onto the existing clock mechanics. Unable to use 10, they chose 9 minutes.
The Antikythera mechanism, an Ancient Greek analog computer used to predict astrological events such as orbits and eclipses. Its complexity wouldn't be matched until more than 1500 years later with astronomical clocks.
The reason we say "o clock" is from the period when mechanical clocks and their sundial predecessors overlapped. To clarify which type of time you were giving you'd say, for example, "10 on the clock" which became "10 o' clock"
"o'clock" is a contraction of "stroke of the clock" and comes from 15th century references to medieval mechanical clocks
the Clocks Turned "Clockwise" Because of Sundials; As The Sun Moves Across the Northern Hemisphere's Sky, The Shadow it Casts Moves Clockwise, and The First Mechanical Clocks Simply Kept Up This Tradition
A mechanical alarm clock was created by an American named Levi Hutchins in 1787. He made the device for himself and it only rang at 4 AM, in order to wake him for his job. The French inventor Antoine Redier was the first to patent an adjustable mechanical alarm clock, in 1847, 60 years later.
The 9 minute alarm clock "Snooze" is a holdover from when clocks had mechanical gears
The Luxor Obelisk was given to France by Ruler of Ottoman Egypt in exchange for a French mechanical clock. The clock turned out to be faulty and the worthless clock still exists to this day in a clocktower in Egypt.
Al-Jazari, a 12th-century Kurdish polymath, invented the crankshaft, piston engine, valve, cam, mechanical clock, combination lock, hydropower driven water supply system, and the first programmable humanoid robot. Leonardo Da Vinci was inspired by his work.

mechanical clocks facts — What type of spring is used in old mechanical clocks?

Why are mechanical clocks important?

You can easily fact check it by examining the linked well-known sources.

In 1900, an ancient bronze and wood device was discovered on a Roman era ship in the Aegean Sea. Dating to the 1st century, the clock-like device was called the Antikythera Mechanism. It was used to track dates and astronomical phenomena and is believed to be the world's first computer.

Abbasid Caliph Harun al-Rashid and Charlemagne sent eachother presents, including horses, clocks, dogs, chess sets, silks, an elephant, mechanical toys and perfume. - source

A Serbian monk named Lazar built the first mechanical clock in Russia in 1404, one of the first in Europe, at the request of Vasily I of Moscow. - source

There were flintlock alarm clocks. The flintlock mechanism would light a candle to assist in awakening the sleeper.

The legendary handgun in the anime “Trigun” is a realistic and manufacturable gun- fit for .45 long Colt ammunition, a “6 o’clock” barrel, and “breaktop” loading mechanism. - source

When were mechanical clocks invented?

The Strasbourg Astronomical Clock made by Jean-Baptiste Schwilgue. It can take into account the anomalies due to the Earth's tilt and orbit as well as the moon's elliptical path and computes the date for Easter based on complex Gregorian calculations, all in a mechanical manner.

How do mechanical clocks work?

Old pennies have kept the clock mechanism of London's Big Ben accurate for the last 150-years. Pennies are stacked on the pendulum, adding or taking away coins effects the pendulum's center of mass and the rate at which it swings (adding one penny = gain two-fifths of a second in 24 hours)

The length of an hour wasn't fixed and commonplace until ~the 14th century. Prior to the invention of mechanical clocks, many people used hours with seasonally varying lengths.

Escapement is the key invention that made all mechanical clocks possible

When were mechanical clocks first invented?

A 13th Century Arab, al-Jazari, invented many things such as the crankshaft, piston engine, valve, mechanical clock, combination lock, programmable and humanoid robot.

There is a plan to build a huge mechanically powered clock designed to last 10,000 years.

Turning a clock's hands counterclockwise while setting it is not necessarily harmful. It is only damaging when the timepiece contains a chiming mechanism.

The mechanical watch was invented to keep time at sea. A pendulum clock with the waves would of disrupted the pendulum therefore not keeping accurate track of the time.

How accurate are mechanical clocks?

There is a plan to build a huge mechanically powered clock designed to last 10,000 years.

The history of clocks. During the first invention, The Egyptians divided the day into two 12-hour periods, and used large obelisks to track the movement of the sun. Later, they used a water-powered escapement mechanism, which transferred rotational energy into intermittent motions.

Jeff Bezos (Richest man in the world) is building a giant 500ft mechanical clock inside of a mountain that is expected to run for 10,000 years

The clockwork mechanism belonging to Big Ben is adjusted using pennies. Adding or removing a penny on the pendulum changes the clock speed by 0.4 seconds per day.

A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than mechanical clocks.
