Automatic vs. Quartz vs. Mechanical Watch Movements: A Quick Comparison
Automatic Watch Movements:
Automatic watch movements, also known as self-winding movements, utilize the natural motion of the wearer's wrist to power the watch. They contain a rotor that rotates with the movement of the wrist, winding the watch's mainspring. These movements are highly regarded for their craftsmanship and traditional watchmaking techniques. Automatic watches require regular wear or winding to keep them running accurately. They offer a smooth sweeping second hand motion, often considered more aesthetically pleasing than quartz movements.
Mechanical Watch Movements:
Mechanical watch movements rely on intricate mechanisms and springs to keep time. They can be further divided into manual winding and automatic (self-winding) variants. Manual winding movements require regular hand winding to keep the watch running. Mechanical movements offer a captivating appeal due to their complex craftsmanship and intricate design. They often have a smooth sweeping second hand motion, similar to automatic movements. Mechanical watches require periodic servicing to ensure optimal performance and longevity.
Quartz Watch Movements:
Quartz watch movements are powered by a battery that sends an electrical charge through a quartz crystal. The crystal oscillates at a precise frequency, generating a reliable timekeeping mechanism. Quartz watches are known for their accuracy and low maintenance requirements. They typically have a ticking second hand motion, moving once per second. Quartz movements are more affordable and widely available compared to automatic or mechanical movements.
