Regarding

water resistance: In daily life, water resistance is suitable for watches with water pressure below 5 atmospheres, but their waterproof coating should be cleaned with caution. Watches with a water resistance depth of 10 to 20 bar or less are suitable for water sports, but for recreational activities such as diving, we recommend choosing a watch with a water resistance depth of 100 meters. Watches manufactured before 2000, such as antique watches, may have lost their water resistance due to age. Even watches with a water resistance depth of 200 meters should be used with care in humid environments.
