When evaluating wrist watches, you must prioritize the Movement Type, which is the heart of the watch. Japanese (Miyota/Seiko) or Swiss (ETA/Sellita) movements are preferred for reliability. Additionally, check the Water Resistance rating (ATM); for daily wear, 3 ATM is standard, while professional divers require 20 ATM or higher. The Case Material should ideally be 316L Stainless Steel for its anti-corrosive properties, and the Crystal should be Sapphire Glass for premium scratch resistance or Mineral Glass for budget-friendly durability.
