For many thousands of years, nobody needed a clock. You got up at dawn to tend your fields, work at your tannery etc. The only alarm clocks were cocks crowing. Then you went home, and when it got dark, maybe after eating and an hour’s conversation around the fire, everyone went to sleep.

The first time-measuring device was the water clock, dating from Greece in the 5th.. century B.C. Water in a vessel was allowed to escape through a pinhole in the bottom, the amount of water and size of the hole determining how long it would take to empty.

Nobody asked “what time is it?” because nobody could measure the time of day and in any case there couldn’t be a universal time because there was no way of comparing with other people in their own village, far less in others. They could guess how far along the day was by the height of the sun, and approximately the passage of a month from the waxing and waning of the moon.

The next step was the candle clock, which appeared in various forms, beginning in China in about 500 A.D. One kind had a candle of known burning rate with hours marked off on the side, or on a sconce behind it:

The first mechanical clocks had a weight hanging from a pulley that turned a geared hand (only one, indicating hours and portions of an hour) but regulating the speed of the hand was rudimentary. Spring-wound clocks appeared in 15th-century Europe. Around 1400 A.D., coiled springs began to be used in locks, and many early clockmakers were also locksmiths.

Here’s something that you’ll find hard to believe. All significant mechanical clock and watch mechanism inventions were not Swiss, but British.

Navigators had always suffered great difficulty in finding their position in longitude (i.e. horizontally round the globe), the world annoyingly rotating instead of standing still. The only way would have been to use published astronomical tables in conjunction with sun or star sights by sextant, but for this you would need to know the time of day to the nearest minute at least, when the most accurate clocks couldn’t keep time to the nearest quarter of an hour on long voyages. And in any event, there was no “zero meridian” or point on the globe from which all time was measured.

Several unfortunate disasters at sea, caused by poor navigation, prompted the British government to create a Board of Longitude empowered to award the huge sum of £20,000 to the first man who developed a chronometer with which longitude could be calculated within half a degree after several days at sea.

John Harrison (born March 1693, in Yorkshire, Eng.—died March 24, 1776, London), the son of a carpenter who was a self-taught mechanic himself, became interested in constructing an accurate chronometer in 1728. He invented the first practical marine chronometer, which enabled navigators to compute accurately their longitude at sea.

Harrison completed his first chronometer in 1735 and submitted it for the prize. He then built three more instruments, each smaller and more accurate than its predecessor. In 1762 Harrison’s famous No. 4 marine chronometer was found to be in error by only five seconds (0.021 degrees of longitude - 1.4 miles) after a voyage from London to Jamaica.

Although his chronometers all met the standards set up by the Board of Longitude, he was not awarded any money until 1763, when he received £5,000, and not until 1773 was he paid in full. £20,000 in 1773 is the equivalent of about $2.5 million today.

The next step was to establish a defining point from which all longitudinal navigation would be based - it was no use saying “according to the log we may have sailed 29 miles last night” - unless there was some fixed point from where you could chart where you were on the face of the globe. Eventually, an international agreement decided where the “zero meridian” would be located. Since the chronometer was a British invention, the spot was established in the Royal Obsevatory, Greenwich, outside of London. You can visit and look at it in the floor; if you straddle it one foot is east and one is west of zero degrees. Incidentally, world time is also based in the zero meridian, known to navigators as Zulu Time. The French have never forgiven the Brits for not acceding to their demand that the zero meridian run through Paris which, as every Frenchman knows, is the center of the universe.

In 1755, an Englishman clockmaker, Thomas Mudge, invented one of the crucial and innovative devices in time measurement, the lever escapement,

a type of mechanism that precisely allows the main spring to very slowly run down while moving the hour, minute and second hands in precise fractions. It was and is still used in almost all mechanical watches, as well as small mechanical non-pendulum clocks, alarm clocks and kitchen timers.

Energy is converted from Mass and vice versa.
