The History of the Watch
Before learning about watches you should be familiar with some of the terminology. The word horology has two meanings; it is the study or science of measuring time or the art of making clocks,Patek Philippe Replica Watches, watches,MontBlanc Replica Watches, and devices for telling time.
Water clocks did not depend on the observation of the sky or the sun. The earliest water clock was found in the tomb of Amenhotep I who was buried around 1500 B.C. Greeks called them clepsydras; they were stone containers with sloped sides that allowed water to drip at an almost constant rate from a small hole in the bottom. Other clepsydras were cylinders or bowl shaped designed to slowly fill up with water coming in at a near constant pace. Markings on the inside of the bowl marked the passage of the hours. Though this was used primarily at night,Burberry Replica Watches, it is thought they were used in the day hours as well. A metal bowl with a hole the bottom was placed in a larger bowl filled with water. It would fill and then sink in a certain amount of time.
The development of quartz crystal clocks and timepieces depended on the crystal size, shape, and temperature to create a frequency. Quartz clocks and watches continue to be popular. They work well enough for the price and although they tend to be slightly ‘off’ the correct time most people can afford them.
Time measurement has been a goal of man from the beginning and a time line will help you understand how we got to where we are with watches. Watches have so many new functions. They have the date,Burberry Replica Watches, the time, times across time zones and some have stop watches. Most watches have some kind of an alarm in them. The possibilities are endless and I can really see a Dick Tracy type of watch being real.
Prior to 1600 – The main problem was the driving power the timepieces ran were balanced weights. This made it difficult to carry them around.
1548 – Other watches appeared and were probably French or German in origin.
1600 – 1675 – This was the age of decoration. Watches became more of a decoration and jewelry piece rather than being functional. The shape of cases changed from tambour cylinder with a lid, to a circular case with hinged, domed covers on the front and back. Champleve enamel and relieved case filled with colored enamel appeared.
1625 – Plain watches came about as the result of the Puritan movement.
1675 – The spiral balance spring is first used in watches. The accuracy now was measured in fractions of minutes as opposed to fractions of hours. This increased accuracy caused watchmakers to create a dial that had a minute hand and was divided by minutes.
1704 – Dullier and Debeaigre developed a method of using jewels as bearings.
1725 – It was common to find a large diamond endstone in the cock.
1761 – John Harrison made a clock that was so accurate it was used to measure longitude during sea voyages.
Purrelet began production of self-winding watches.
1800 – The pocket chronometer was a readily available and accurate watch.
1850 – The United States were the first to use mass production with mixed results
1952 – Battery powered watches became available.
Watches today use quartz crystals, batteries, and there are even atomic watches. Time tracking has never been more accurate and advances in the field of Horolgy are being made all the time.
