An automatic is similar to a mechanical watch, but it winds up on its own. Inside is a small rotor, which responds to your movements throughout the day and keeps the mainspring tight.
These days, the most popular type of watch uses quartz movement. The quartz piece is subjected to a small electric current from a battery, which causes the quartz to vibrate 32,768 times per second. This vibration is measured and turned into a pulse, which moves the second hand round the face.
Modern watch brands, such as Fossil, use the quartz movement and design a range of sleek, contemporary watches.
