Seiko Prospex SRPH57 King Turtle Shell Special Edition Oceanic Society Green

Introducing three Special Edition Prospex timepieces emphasizing Seiko's ongoing efforts to promote ocean exploration and conservation. In addition to an official partnership with PADI, the world's leading scuba diver training operation, and sponsorship of PADI Project Aware and the Scuba Diving magazine Sea Hero Awards, Seiko has announced its official sponsorship of Oceanic Society, America's first ocean conservation non-profit, and its global work to study and protect endangered sea turtles.

For over 50 years, the Oceanic Society has worked to foster an appreciation for the world's oceans, dedicated to forging a connection between the people of the globe and its waterways. With this sponsorship, Seiko is helping with expanding its efforts to promote ocean exploration and conservation. A portion of the proceeds will go directly toward the Oceanic Society's work.
