Quartz movements are a type of watch mechanism that uses a battery to power a small quartz crystal. When electricity from the battery passes through the crystal, it vibrates at a precise frequency, which helps keep accurate time. This technology is known for its reliability and low maintenance needs compared to traditional mechanical movements. These movements are commonly found in both analog and digital watches. They are often more affordable than mechanical watches, making them popular among consumers. Brands like Seiko and Citizen are well-known for their high-quality quartz timepieces, offering a wide range of styles and features.
