Mechanical vs. Quartz: Understanding Core Differences
cnJoya spreadsheet contributors emphasize that movement type significantly impacts a watch's character and maintenance needs:
- Mechanical Watches: Powered by intricate gear systems, these exemplify traditional craftsmanship. Automatic variants harness kinetic energy from wrist movement, while manual versions require regular winding.
- Quartz Watches: Battery-operated with superior accuracy (+/- 15 seconds monthly) and lower maintenance. Ideal for buyers prioritizing precision and convenience.
The guides suggest mechanical pieces for collectors valuing horological artistry, while quartz models better suit daily practicality.
