If you are noticing a lot of clocks and watches you might be worried about the time. You are either in a rush or you are waiting for something to happen.
Warren Marrison, who invented the first quartz clock in 1927.
12 hour clocks were invented in 1781 by a group of concerned citizen who could not tell time in digits
The first clocks ever used were actually invented by the Egyptians. These clocks were sun dials that used the shadows to tell time.
Clocks were not discovered they were invented.
Quartz is used in timepieces such as watches or clocks.
yes, quartz is used in watches and the quartz watches are known as best watches in the world
A quartz clock is a clock that uses an electronic oscillator that is regulated by aquartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Quartz timekeepers are the world's most widely-used timekeeping technology, used in most clocks and watches, as well as computers and other appliances that keep time.Source: http://en.wikipedia.org/wiki/Quartz_clock

the collective term for watches timers or clocks is either chronometer
They get their power from a battery, and then usually a quartz piece measures the time. Check www.referenciarelojera.com, you can ask any question there, its in spanish though cheers!
Pocket watches, chimney clocks, sun dials, church clocks. Only wrist watches are from a later date.
Quartz watches actually use quartz crystals to keep time. Quartz is related to the time keeping mechanism. Quartz watches can also have digital display.The word 'digital' refers only to the display and not mechanism type.

Yes all quartz watches need a battery to work.
