The heart of the movement, receiving the energy to run from the escapement.

A watchmaker can make the balance wheel oscillate faster or slower, which in turn makes the watch run faster or slower.

Another series of gears that transmit the regulated, equally metered energy from the balance wheel to the hands of the watch, making them move.

Even though battery watches are inherently more accurate, almost all collectors and connoisseurs prefer manual or automatic as these movements represent the accumulation of almost 600 years of refinement, expertise, and craftsmanship.

Manual Movement Automatic Movement Quartz Movement A manual movement, frequently called a hand-wound movement, is the oldest type of watch movement made, dating back to the 16th century. Manual movements are the most traditional movements and are usually found in very conservative, expensive, and collectable watches. The kinetic energy from winding the crown is transferred to the coil-shaped mainspring, which stores the energy by getting tighter and tighter.

A movement is what makes a watch “go.” Most watch companies purchase either the entire movement or parts of the movement from other companies.

There are a handful of companies that are ‘vertically integrated’ and make their own movements without using any supplies from subcontractors.

A half circle-shaped metal weight attached to the movement that can swing freely in 360 degrees as the wrist moves. A quartz movement uses a battery for its power source and does not need winding like a mechanical watch.

The rotor is connected by a series of gears to the mainspring and as it turns, it winds the mainspring, giving the watch energy. The gear train transfers the energy to the escapement. The escapement meters out the energy into regulated parts. The balance wheel uses this regulated energy to beat back and forth at a constant rate. Every certain number of beats, the dial train transfers the energy to the hands of the watch. It is the most accurate type of movement currently being produced.

It is important to replace the battery as quickly as possible once it has died as there is a possibility of it leaking acid and damaging the movement.

This ‘carries’ the electrical charge between the various parts of the quartz movement.

Functions just like the dial train found on a mechanical movement. Electricity is carried from the battery to the quartz crystal via the integrated circuit. The electricity makes the quartz crystal vibrate at a rate of 32,768 per second. These electrical pulses are sent via the integrated circuit to the stepping motor. The stepping motor sends every 32,768th electrical pulse to the dial train.
