Hints for water-resistance: frequent contact with water, especially corrosive or high temperature water like in a hot bathtub, will cause the waterproof gasket to deteriorate pre-maturely, leading to loss of water-resistance even if it is a diving watch. The manufacturer or distributors are not liable for any damage caused by improper use, such as failure to screw the crown tightly before submerging into water. So please make sure the crown is screwed very tightly before jumping into the water.
