WATCH
Portable timepiece designed to be worn on the wrist or carried in the pocket. The first watches appeared shortly after 1500, when the mainspring was invented as a replacement for weights in driving clocks. The progressive miniaturization of electronic components in recent decades has made possible the development of all-electronic watches, in which the necessary transistors, resistors, capacitors, and other elements are all on one or several miniature integrated circuits, or chips. Such circuitry enables them to perform several timekeeping functions and also makes possible digital readouts of the time.
There are several parts of the wrist watch. Some of them are described below.
MOVEMENT:
A movement in watch making is the instrument that measures the passage of time and shows the present time (and other information including date, month and day). Movements could be entirely mechanical, entirely electronic (potentially with no moving parts), or an intermingle of these both.
Mechanical movements use an escapement mechanism to organize and bound the unwinding of the spring, changing what would otherwise be a uncomplicated unwinding, into a controlled and episodic energy release. Mechanical movements also use a balance wheel jointly with the balance spring (it is also known as a hairspring) to control movement of the gear system of the watch in a manner analogous to the pendulum of a pendulum clock.
Electronic movements have little or no moving parts, as they use the piezoelectric effect in a tiny quartz crystal to endow with a stable time base for a majorly electronic movement. The crystal forms quartz oscillators which reverberate at a specific and extremely stable frequency, and that could be used to accurately pace a timekeeping mechanism.
SOURCES OF POWER:
Traditional mechanical watch movements use a spiral spring called a mainspring as a source of power.
Electronic watches need electricity as a source of power. Some mechanical actions and hybrid electronic-mechanical movements also need electricity. Generally the electricity is provided by a replaceable battery. Watch batteries are especially designed for their purpose. They are very minute and provide tiny amounts of power constantly for very extended periods.
DISPLAY
ANALOG:
Conventionally, watches display the time in analog form, with a numbered dial on which are joined at least a rotating hour hand and a longer, rotating minute hand. Most of the watches also slot in a third hand that shows the current second of the current minute.
DIGITAL:
Digital displays are mostly used in the sports watches most of them are used in water sports and racing games. LED is used mainly in these kinds of watches.
