I'm talking about the Prospex Save The Ocean (STO) series. First introduced in 2018, this line link of special edition watches is updated annually link with a new take on an older Seiko design, highlighting a variety of marine animals that one might encounter on an exotic dive trip. We've had Seiko Turtles with dials inspired by humpback whales, Seiko Monsters with dials that riff on penguin tracks, link and even Seiko Samurais that reflect Manta Rays onto their dial surface.
