Diving watches are specially designed timepieces that can withstand underwater conditions. They are built to be water-resistant, typically rated to depths of at least 100 meters. Features often include a unidirectional rotating bezel for tracking dive time, luminous hands and markers for visibility in low light, and a robust case to protect against pressure. These watches are popular among both professional divers and enthusiasts. Many brands, such as Rolex and Seiko, offer diving watches that meet international standards set by organizations like ISO for underwater use. Their durability and functionality make them suitable for various water activities beyond diving.
