TYPES OF WATCH MOVEMENTS

A watch movement (also known as a “calibre”) is the engine of a watch that acts as the powerhouse to make the watch and its functions work. This internal mechanism inside the timepiece moves the hands and powers any complications such as a chronograph, annual calendar or a dual time zone. Driving all of the timekeeping functions, the movement is the essential component in a watch and keeping accurate time; a watch would not function without it.

There are countless different movements that are created by watch manufactures utilizing proprietary innovations, but each of these movements will fall into one of two categories—quartz or mechanical.
 
An easy way to differentiate a quartz from a mechanical movement is by looking at the second hand. On a quartz watch, the second hand has the tick-tick motion that moves once per second while mechanical watches have a smooth, sweeping seconds motion.
