Regarding：

water resistance: Water resistance is effective for watches exposed to pressures below 5 atmospheres in daily life, but care should be taken not to overuse cleaning agents on the waterproof packaging. Watches water-resistant to 10-20 bar are suitable for water sports, but for recreational activities such as scuba diving, we recommend watches water-resistant to 100 meters. Models manufactured before 2000, such as antiques, may lose their water resistance due to aging and other factors. Even watches with 200m water resistance should be handled with care in damp environments.
