Collectors adore these highly decorated clocks, and it is possible to get them made and repaired using the original schematics.ġ821- The stopwatch was invented in France by Nicolas Mathieu Rieussec. These early pocket watches are highly collectible.ġ775- The first cuckoo clock was crafted in what is now modern-day Germany. This invention allowed for smaller pocket watches to evolve from the larger, pendant-style watches. By 1876 a song called “ My Grandfather’s Clock” was popular.ġ675- The spiral watch spring is invented. ![]() Late 1600s- Longcase clocks (which are now called grandfather clocks) enter the market. Clocks were still set, however, using sundials. Dutch astronomer Christiaan Huygens’s invention of the pendulum in 1657 increased their reliability. ![]() His watches were ornamental and meant to be worn as pendants or attached to clothing.ġ657- One issue with early clocks is that they were not very reliable. During the 16th century, some very wealthy people had clocks at home, but they were costly and scarce.ġ510- The invention of the watch. The clock was taken down in the 19th century but restored in the 20th century using careful repair techniques and historical engineering methods.ġ450- The coiled spring was invented, and made portable clocks possible. Like most clocks of its age, it doesn’t have a face. The oldest working clock in the world is located at Salisbury Cathedral. The melting of the candles acted as a counterweight that caused the clock hands to move.ġ309- The first mechanical clock is recorded. The candle clock is more of a timer than a clock in modern understanding.ġ206- Ismail al-Jazari, a Turkish inventor, designed a more sophisticated candle clock that actually displayed time instead of merely measuring it. Each candle took four hours to burn, and each marking represents 20 minutes of burning time. Six candles, each 12 inches high and of the same thickness divided into 12 sections each. Inflow clocks work by filling up a marked container conversely, outflow clocks work by water flowing out of the original container and showing marks measuring the progression of time.ĥ20- Candle clocks were first mentioned in a Chinese poem written in 520 AD. There are two kinds of water clocks: inflow and outflow. Although it is believed that water clocks were used all the way back in Babylon, the first known example is from the tomb of Pharaoh Amenhotep I. They were used as far back as ancient Iran and ancient Egypt and were in everyday use until the 19th century.Ģ000 BC- The Sumerians invent the sexagesimal system of time measurement still in use today.ġ500 BC- The Egyptians invented the water clock. Pre-2000 BC- The sundial is one of the earliest man-made ways to tell time. Modern mechanical clocks all work similarly–with gears, mainsprings, pendulums, and weights. ![]() During the Industrial Revolution, clocks began to resemble their modern counterparts and the way we perceived time was changed forever. The 1700s saw a marked increase in clock-related technology. Important time-telling inventions like the sundial and hour-glasses have contributed to the sophisticated and high tech clocks and watches we enjoy today. From inventors in ancient Greece to those in medieval Europe, many have toyed with new ways of tracking the seconds, minutes, hours, days and telling time. Humans have always been fascinated by time.
