Watch movements, also known as calibers, are the mechanisms that power timepieces. They are responsible for keeping time and driving the watch's hands. There are primarily two types of movements: Mechanical and Quartz. Mechanical movements are further divided into manual and automatic, while quartz movements rely on a battery and a quartz crystal to maintain accuracy. The choice of movement affects not only the watch's performance but also its craftsmanship and value. High-end watches often feature intricate mechanical movements, showcasing the artistry of watchmaking. In contrast, quartz movements are known for their precision and affordability, making them popular among everyday consumers.
