Watches are categorized into mechanical and quartz types. The lifespan of each type depends on various factors like quality, maintenance, and usage.
Quartz Watches:
- Generally last around 10 years under normal use.
- Short-term lifespan issues: Battery depletion, coil short circuits, quartz oscillator leaks, and CMOS circuit damage. These can be fixed with replacements.
- Long-term lifespan: Mainly concerns the wear of main and small plate holes. Quartz watches with plastic plates and gears may face aging issues.
Mechanical Watches:
- Low-end: Prone to wear due to inferior materials.
- Mid to high-end: Better materials, hence more durable. Regular maintenance, such as oiling every 4-5 years, is crucial. If not maintained, the lack of lubrication leads to axle wear, reducing the watch's lifespan.
Note: Timely battery replacement for quartz watches and regular winding for mechanical watches are essential for longevity.
