About waterproof function

Water resistance is effective for watches with a pressure of less than 5 atm in daily life, but the packing that plays the role of water resistance requires caution against excessive use of detergents. A watch with a water resistance of 10 to 20 bar or less is suitable for water sports, but for leisure such as scuba diving, we recommend a watch with a water resistance of 100 m. Models manufactured before 2000, such as antiques, may not maintain their waterproof function due to various reasons such as deterioration over time. Even if it is a waterproof watch for 200m, please be careful when using it in a wet place.

Email settings

It may be classified as a junk mail folder, so please check it once. Please contact your mobile phone company for reception rejection settings and filter cancellation.
