To ensure product longevity and market competitiveness, focus on the Movement Type (Japanese Quartz like Miyota or Seiko for reliability, or Swiss movements for luxury positioning). The Case Material should ideally be 316L Stainless Steel for its anti-corrosive properties, while the Crystal should be Sapphire Glass for scratch resistance in premium models, or Hardened Mineral Glass for budget-friendly best-sellers. Additionally, verify the Water Resistance (ATM) rating; a minimum of 3ATM (30 meters) is standard for daily wear, while 10ATM is required for sports or diving watches.
