Why are watches categorized into mechanical, quartz, and smart watches? How can one properly maintain a watch and prolong its lifespan?

The classification of watches primarily relies on their driving mechanism and core structure. Pure mechanical watches rely on the power stored in the spring to drive the precision movement, eliminating the need for batteries. They are crafted with intricate techniques and a strong sense of heritage, but require regular manual winding or maintaining power through wear. Quartz watches are powered by batteries that drive the high-frequency vibration of quartz crystals, ensuring precise timekeeping and low maintenance costs, but necessitate regular battery replacement. Smartwatches, on the other hand, blend traditional watchmaking craftsmanship with digital technology, offering various functions such as activity monitoring, heart rate tracking, and information reminders. However, their battery life is relatively short and they rely on software updates and the electronic device ecosystem. Regardless of the type chosen, daily maintenance cannot be overlooked. Avoid exposing the watch to strong magnetic fields to prevent the movement from becoming magnetized, which can lead to inaccurate timekeeping. Keep it away from chemical cleaners, perfume, and prolonged exposure to sweat to prevent corrosion of the case and strap materials. Mechanical watches should undergo professional maintenance and movement cleaning regularly, generally recommended every three to five years. Leather straps should be avoided from water and direct sunlight, while metal straps can be wiped with a soft cloth dampened with a small amount of water and allowed to air dry naturally. Proper wearing habits and regular maintenance can keep your watch accurate in timekeeping and accompany you for a longer period of time.
