Cura de la resistència a l'aigua

While your G-Shock is water resistant to 200 meters, it is important to rinse the watch with fresh water after exposure to saltwater or chlorine to prevent corrosion. Do not operate buttons while the watch is submerged in water or wet, as this can compromise the water resistance seals.
