    The first mechanical clocks were invented in Europe around the start of the 14th century and were the standard timekeeping device until the pendulum clock was invented in 1656. Many components came together over time to give us the modern-day timekeeping pieces of today. Take a look at the evolution of those components and the cultures that helped ...

    Ancient Egyptian obelisks, constructed about 3,500 B.C., are among the earliest shadow clocks. The oldest known sundial is also from Egypt; it dates back to around 1,500 B.C. Sundials have their origin in shadow clocks, which were the first devices used for measuring the parts of a day.

    The Greeks inventedan early prototype of the alarm clock in around 250 BC. They built a water clock, called a clepsydra, where the rising waters would keep time and eventually hit a mechanical bird that triggered an alarming whistle. Clepsydras were more useful than sundials—they could be used indoors, during the night, and also when the sky was cl...

    The earliest mention of candle clocks comes from a Chinese poem, written in 520 A.D. According to the poem, the graduated candle, with a measured rate of burn, was a means of determining the time at night. Similar candles were used in Japan until the early 10th century.

    Hourglasses were the first dependable, reusable, reasonably accurate, and easily constructed time-measurement devices. From the 15th century onwards, hourglasses were used primarily to tell time while at sea. An hourglass comprises two glass bulbs connected vertically by a narrow neck that allows a regulated trickle of material, usually sand, from ...

    Church life and specifically monks calling others to prayer made timekeeping devices a necessity in daily life. The earliest medieval European clockmakers were Christian monks. The first recorded clock was built by the future Pope Sylvester II around the year 996. Much more sophisticated clocks and church clock towers were built by later monks. Pet...

    In 1504, the first portable timepiece was invented in Nuremberg, Germany by Peter Henlein. It was not very accurate. The first reported person to actually wear a watch on the wrist was the French mathematician and philosopher, Blaise Pascal(1623-1662). With a piece of string, he attached his pocket watch to his wrist.

    In 1577, Jost Burgi invented the minute hand. Burgi's invention was part of a clock made for Tycho Brahe, an astronomer who needed an accurate clock for stargazing.

    The first mechanical alarm clock was invented by American Levi Hutchins of Concord, New Hampshire, in 1787. However, the ringing bell alarm on his clock could ring only at 4 a.m. In 1876, a mechanical wind-up alarm clock that could be set for any time was patented (No. 183,725) by Seth E. Thomas.

    Sir Sanford Fleminginvented standard time in 1878. Standard time is the synchronization of clocks within a geographical area to a single time standard. It developed out of a need to aid weather forecasting and train travel. In the 20th century, the geographical areas were evenly spaced into time zones.

  3. 1577 - Jost Burgi invented the minute hand, even though 16th century clocks were very inaccurate. 1581 – Italian astronomer and physicist Galileo discovered the properties of pendulum. 1587 – Geneva became home to the thriving watchmaking industry.

  4. Feb 25, 2021 · Clock tower building slowed down in the twentieth century. Watches became more affordable, and smaller wristwatches became fashionable. It is not uncommon to see public clocks now telling the wrong time, as those who serviced them have moved on with tighter budgets, and less need.
