When evaluating quartz watches, the movement is the most critical component; prioritize reputable manufacturers like Japanese Miyota or Seiko (Hattori), or Swiss Ronda for higher-end positioning. Ensure the battery life spans at least 2 to 3 years. For the casing, 316L Stainless Steel is the industry standard for durability and corrosion resistance, while Sapphire Crystal glass is preferred over mineral glass for its superior scratch resistance. Additionally, verify the Water Resistance (WR) rating, typically 3ATM for dress watches and 10ATM or higher for sports models.
