What do the different movement types mean?
Automatic Movement (Automatic Winding or Self-Winding): Powered by the motion of the wearer’s arm rather than by turning the winding stem. In response to this motion, a rotor turns and winds the watch’s mainspring so that it keeps accurate time. Most automatic watches have up to 36 hours of power reserve. If an automatic watch is not worn for a day or two, it will need to be wound by hand to restart again. Mechanical Movement: A watch’s mechanical movement is based on a mainspring which slowly unwinds in a steady motion to provide accurate timekeeping. As opposed to a manual mechanical watch, which needs to be wound on a consistent basis, an automatic mechanical watch requires no winding because its rotor winds the mainspring when the wearer moves their wrist. Read the section on automatic watch maintenance for more details. Quartz: Quartz is a caliber that uses the vibrations of a tiny crystal to maintain timing accuracy. The power comes from a battery that must be replaced about ever
