the maker and the first sand clock is unknown
1787 in New Hampshire.
He got the idea from the war. He also invented the day light savings time!!!!!=)
In the 1920's the first Quartz were invented. This works by applying a certain voltage and pressure inside the clock. This will vibrate or oscillate the Quartz at a constant rate. This vibration moves the hands on the clock in a very precise manner, making them very cheap and very accurate. These are the clocks are used everyday in our houses, offices and schools and in many cases wrists. There are other types of clocks, such as atomic clocks, but these are not widely used and are not yet perfected.
The first atomic clock was invented in 1948 by the US Bureau of Standards.The first practical atomic clock was invented by English physicist Louis Essen in the 1955.Atomic clocks use the energy changes that take place in atoms to keep track of time. Atomic clocks are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.The most accurate, modern-day atomic clocks will neither lose nor gain a second in 168 million years.
In 1927 Warren Morrison developed a very large and accurate clock by testing the vibrations of a quartz crystal from an electrical circuit. In 1504 Peter Heinlein Nuremberg created the very first wrist watch in Germany.
no body is sure in which year the sun clock was invented but we think it was invented by the greeks or roman or egyptians
digital clocks were made in 1956 the digital clock was invented in 1956, it is the opposite to analogue.
He invented clocks and watch-glasses
I wouldn't say the inventor, had a reason for calling clocks clocks, the person in which invented clocks came up with the name himself
1962
the ancient egyptians.
1956 AD
cuckoo clocks were invented in Germany around 1730
