Ever since its first diver’s watch in 1965, Seiko has developed new technologies, features and designs that have made the Seiko Prospex diver’s watch collection a favorite among professional and recreational divers the world over. Through more than a half-century of innovation, Seiko has continuously pushed back the boundaries of where sports watches, and diver’s watches in particular, can go and how they can be used.Â
