![]() ![]() Swiss John Harwood invented the self-winding watch in 1923. On Octoa mechanical wind-up alarm clock that could be set for any time was patented (#183,725) by Seth E Thomas. However, the ringing bell alarm on his clock could ring only at 4 am. The first mechanical alarm clock was invented by Levi Hutchins of Concord, New Hampshire, in 1787. The Greeks built a water clock where the raising waters would both keep time and eventually hit a mechanical bird that triggered an alarming whistle.

The Latin for bell is glocio, the Saxon is clugga and the German is glocke. The word 'clock' comes from the French word "cloche" meaning bell. Building on earlier work in piezoelectricity, he developed a very large, highly accurate clock based on the regular vibrations of a quartz crystal in an electrical circuit" - the first quartz clock. With a piece of string, he attached his pocket watch to his wrist.Īccording to the Smithsonian "In 1927, Canadian-born Warren Marrison, a telecommunications engineer, was searching for reliable frequency standards at Bell Telephone Laboratories. The first reported person to actually wear a watch on the wrist was the French mathematician and philosopher, Blaise Pascal (1623-1662). In 1504, the first portable (but not very accurate) timepiece was invented in Nuremberg, Germany by Peter Henlein. In 1656, the pendulum was invented by Christian Huygens, making clocks more accurate. Burgi's invention was part of a clock made for Tycho Brahe, an astronomer who needed an accurate clock for his stargazing. In 1577, Jost Burgi invented the minute hand.
