When evaluating wristwatch quality, focus on the movement type, case material, and crystal quality. For high-end markets, prioritize Japanese (Miyota/Seiko) or Swiss movements for reliability. The case should ideally be made of 316L Stainless Steel for corrosion resistance. For the watch face, Sapphire Crystal is the industry standard for scratch resistance, while Mineral Glass serves as a cost-effective alternative for budget lines. Additionally, verify the Water Resistance (ATM) rating; a minimum of 3 ATM (30 meters) is required for daily use, while 10 ATM or higher is necessary for sports or diver watches.
