Quartz and Mechanical Watch Movements Explained

[Harley Otto]

  Watch movements are the mechanism by which a watch measures and displays time. They may be either mechanical or quartz, with variations of each. The mechanical movement has been used by the watch-making industry for centuries while the quartz movement was first introduced in 1964 at the Tokyo Summer Olympics by Seiko. Both types of movements and the accuracy of each are discussed below.

  Mechanical Movements

  Traditional mechanical movement watches use the energy of a spiral wound spring, referred to as the mainspring, to measure time by highly regulating the release of energy by the spring with a series of gears, referred to as the wheel train, and an escapement mechanism to limit and control the winding and unwinding of the mainspring into a periodic and controlled release of energy.

  They also use a balance wheel in conjunction with a balance spring, referred to as a hair-spring, to control the motion of the gear system similar to the pendulum in clocks. A tourbillion, an op...       More information,please visit>>http://www.replicafire.com/corum/
