For watch manufacturers, adventure sports represent the greatest challenge of all. Since Seiko made its first diving watch in 1965, the venerable Japanese manufacturer has been exceeding the expectations of those whose sports require watches with truly professional specifications, whether in land, in sea, or in sky.

The Seiko Prospex King Samurai adheres to this purpose-built ethos, while this reference SRPG21 pays tribute to the Professional Association of Diving Instructors (PADI) – the world's foremost a recreational diving training organization, founded in 1966. In addition to adding in a suite of premium upgrades over the standard fan-favorite Samurai, like a ceramic bezel insert and a sapphire crystal, this reference bears the PADI badge at 6:00, and features the signature PADI globe embossed into the dial.
