Seiko’s Save The Ocean series reimagines some of the brand’s most famous dive watch designs to create special edition timepieces that help raise awareness and generate funds to support a variety of different marine conservation efforts around the world. First launched in 2018, the collection is updated annually, and the latest additions to the series takes two of the brand’s most iconic divers of all time and uses their classic case silhouettes to serve as the foundation for striking ocean renditions that draw their aesthetic inspiration from the Arctic waters and glacial structures experienced by ice divers and polar explorers.

The Seiko SRPH77 takes the Tuna aestheic we love and adds this rich antarctic blue dial with penguins swimming near 9 o'clock. The overall image feels like you're looking up from the depths of the ocean at these beautiful creatures.That same dial is used on the SRPH75 "Monster", which offers a more compact wear.

Despite their differences, both of these Seiko Prospex Save The Ocean watches feature cases that are crafted from stainless steel, hardlex crystals protecting their dials, and screw-down winding crowns with solid casebacks to help provide them with an ISO-certified 200 meters of water resistance.

Seiko will be donating a portion of the proceeds from the Seiko Prospex Save the Ocean collection to give back to the diver's community that is removing and reporting marine debris in aquatic environments.
