I need some help here. Read this line from the sales description of a Seiko watch. Water-resistant to 30 meters, this watch can handle splashes of water or rain, but it should not be worn while swimming or diving. It has a battery life of five years.
Water resistant to 30m (100 ft) but I can't go swimming with it? I hope I am never in a 30m splash of water.
