http://www.watchessalebest.com ocket watch is a time measure item that managed to infuse itself into culture and development of our modern civilization for unusually long period of time. Ever since its development in 16th century to the time of World War one in 20th century, pocket watches represented not only the most popular type of portable clock design, but also an integral part of male fashion.History of pocket watches started in early late 1400s and early 1500s when mechanical engineering reached the state when simple spring devices could be made. By using the invention of mainspring, German inventor Peter Henlein was finally able to create watches that did not require falling weights as the source of their power. This invention gave birth to the first wave of small portable watches, which were in the beginning worn as a pendant on a chain around the neck.Bu 1524 Peter Henlein produced pocket watches regularly, enabling his innovative designs to spread across Europe during the reminder of 16th century. Early models of mainspring powered watches were round (often egg-shaped) and bulky, but the introduction of screws in 1550s enabled them to gain modern flatten shape that we know today. Another distinctive feature of those early designs was the lack of glass ¨C the only protection from the outside influences was bras lid.Between 1880 and 1900 saw the first attempts of standardizing time, not only for creation of time zones but also because of ever increasing need of precise time measurements in many scientific experiments and public transportation systems (famous Ohio train wreck of 1891 happened because of train engineer watches were 4 minutes out of sync).By the time of World War I, pocket watches went out of fashion after highly miniaturized wrist watches became famous.

In our previous episode, we traveled back in time to look at some of mankind¡¯s most ingenious inventions that made timekeeping possible. We began by examining 5,000 years old Egyptian sundials and water clocks, continued to the assembly of the first mechanical clock that was invented by Pope Sylvester II over a thousand years ago, and ended in 1865, with the invention of the world¡¯s first truly accurate timekeeping device, the pendulum clock. In today¡¯s episode, we¡¯ll take a step back in order to understand how the final stage in the evolution of timekeeping devices came about: how wrist watches were born.Around the year 1400, an unknown locksmith, probably from Nuremberg, invented something we call today ¡°the main spring¡± ¨C a coiled spring which he used to improve the functionality of his locks. Since many locksmiths at the time were also clockmakers, the spring soon found itself applied in clocks, as a device that could be wound to store energy, which could then be released over a long period of time.Timekeeping devices started appearing at the very dawn of modern human civilizations, and ever since then they received steady rate of upgrades and innovations that enabled us to create modern world that we live in today.
http://www.watchgetluxury.com According to the Guinness Book of Records, the first wrist watch was designed for the Countess Koscowicz of Hungary in 1868. It was simply an undersized pocketwatch embedded in a bracelet. But, the concept didn¡¯t really become popular until WWI. During the war, in order to improve synchronization between soldiers during maneuvers, the men were equipped with wrist watches (which at first consisted of nothing more than a relatively small pocket watch and a leather-strap it attached to). By the time the war ended, millions of men returned home wearing a wrist watch ¨C and the fashion soon caught on.Clocks have been with us since the dawn of ancient human civilizations, and ever since then we always strived to improve them, make them more portable, reliable and easier to produce. Here you can find everything that you need to know about history of this influential device.
