Peter Hele, still a young man, fashions works which even the most learned mathematicians admire. His fame is based on a passage by Johann Cochläus in 1511, He was one of the first German craftsmen who made "clock-watches", ornamental timepieces worn as pendants, which were the first timepieces to be worn on the body. Nuremberg clockmaker Peter Henlein (or Henle or Hele) (1485-1542) is often credited as the inventor of the watch.
TIMEMAKER SMARTWATCH PORTABLE
Portable timepieces were made possible by the invention of the mainspring in the early 15th century. The first timepieces to be worn, made in the 16th century beginning in the German cities of Nuremberg and Augsburg, were transitional in size between clocks and watches. Ī pomander watch from 1530 once belonged to Philip Melanchthon and is now in the Walters Art Museum, Baltimore The Oxford English Dictionary records the word watch in association with a timepiece from at least as early as 1542. Another theory surmises that the term came from 17th-century sailors, who used the new mechanisms to time the length of their shipboard watches (duty shifts). One account of the origin of the word "watch" suggests that it came from the Old English word woecce which meant "watchman", because town watchmen used watches to keep track of their shifts. Although mechanical watches still sell in the watch market, the vast majority of watches as of 2020 have quartz movements. During the 1980s quartz watches took over the market from mechanical watches, a process referred to as the " quartz crisis". In the 1960s the invention of the quartz watch which ran on electricity and kept time with a vibrating quartz crystal, proved a radical departure for the watchmaking industry.
The watch was developed by inventors and engineers from the 16th century to the mid-20th century as a mechanical device, powered by winding a mainspring which turned gears and then moved the hands it kept time with a rotating balance wheel. The history of watches began in 16th-century Europe, where watches evolved from portable spring-driven clocks, which first appeared in the 15th century.
