A diving watch was initially a particular instrument only for professional divers. Today choosing a diving watch even if you don’t scuba dive for a living is a smart choice. Their functions and water resistance make them both enduring and functional. Diving watches must be water-resistant to at least 200 m (20 bar, 656 feet). They feature luminescent hands and indices that can be read underwater and a unidirectional bezel with minute and five-minute markers. The most famous diving watch is the Rolex Submariner, but many brands such as Delma manufacture great dive watches such as the Blue Shark III with a water resistance of 4000 m!
