Mechanical watches are seen as art. They are complex and sophisticated, and do not require a battery. There are two types of mechanical watches, manual and automatic. Automatic uses a rotor, which is a device that transfers energy from movement, that in turn - powers the watch. The manual does not have a rotor, and is hand wound. The difference? Purely being preference.
The quartz movement requires a battery as its primary power source. This battery sends an electric-current through a small quartz crystal which creates dial vibrations. These vibrations are what makes the dial move and drives the motor. The difference between quartz and mechanical movement is that quartz watch offers individual second 'ticks' versus the sweeping motion of the mechanical watch.
The watches case diameter is the entire diameter of the dial of the watch. This is also known as the 'face'.
This is the thickness or depth of the watch face. The thickness is also dependent on the diameter & style of the piece. If the watch is 40mm in diameter, generally the thickness would sit around 8mm.
