The main difference between a quartz watch and an automatic watch is their power source. While a quartz watch is battery powered, an automatic watch relies on the energy and movement of a wearer's hand to power it. While the battery in a quartz watch will last a long time it will eventually need replacing, while automatic watches can go for many years, as long as it is worn consistently. Automatic watches are celebrated for their craftsmanship and are an ideal choice for the stylish collector, prized for their complex mechanisms. The appearance of movement can also be fascinating, being able to see the inner workings of most automatic watches from the back of their cases. While quartz watches are renowned for their precision and minimal upkeep, requiring no manual adjustments. Quartz watches are also thinner, lightweight and durable, thanks to their simpler design and fewer moving parts, making them a great everyday timepiece. The best quartz watch or automatic watch all comes down to personal preference. When choosing your own, consider how it will fit with your lifestyle and needs, and pay close attention to its quality and design.
