 As well as their exterior beauty, watches are also an incredible feat of engineering and craftsmanship. Several complicated parts must all work simultaneously in order to tell time. Today's watch however, performs a myriad of other functions. |

Watch Parts Here is an overview of the major parts of a watch, as well as an explanation of how watches operate.
Watches essentially tell time by the integration
of three main components: an energy source, a time regulating
mechanism and a display. The energy source can be electronic (as in
a battery) or mechanical (as in a wound spring).
A watch’s main timekeeping
mechanism is called its movement. Today’s watches fall into two
categories:
Mechanical movements and Quartz movements. Here’s a
breakdown of how each type of movement works:
Mechanical watches are made
up of about 130 parts that work together to tell time.
Automatic mechanical
movements mark the passage of time by a series of gear mechanisms,
and are wound by the movement of your wrist as you wear it. The gear
train then transmits the power to the escapement, which distributes
the impulses, turning the balance wheel. The balance wheel is the
time regulating organ of a mechanical watch, which vibrates on a
spiral hairspring. Lengthening or shortening the balance spring
makes the balance wheel go faster or slower to advance or retard the
watch. The travel of the balance wheel from one extreme to the other
and back again is called oscillation. A series of gears, called the
motion work, then turns the hands on the watch face, or dial.
