Mechanical movement: No battery required, automatic winding. However, correct manual winding is essential to effectively reduce time deviation. (Note: Mechanical watches are different from quartz watches. Insufficient mechanical kinetic energy will cause the watch to stop, please wind it in time.)
Business Watch: High-quality electroplated case, no fading. High-hardness mineral glass can effectively prevent wear and tear, and the durable all-steel case and strap provide you with a comfortable wearing experience.
Waterproof watch (30 meters): Hand wash, swimming, no problem! Note: Do not press any buttons in water or wear this watch for long-term underwater activities such as diving, etc.
