When evaluating watch quality, focus on the Movement Type, Case Material, and Water Resistance. For high-end markets, prioritize Swiss or Japanese automatic movements (e.g., Miyota, Seiko NH series) for reliability. The case should ideally be made of 316L Stainless Steel for its anti-corrosive properties. Ensure the Water Resistance rating (ATM) matches the intended use: 3ATM for daily wear, 5ATM for swimming, and 10ATM+ for diving watches. Additionally, specify Sapphire Crystal glass over mineral glass to ensure superior scratch resistance.
