Seiko Prospex Save The Ocean 'King Turtle' Limited Edition Blue Dial Men 45mm SRPF77K1

Seiko Prospex SRPF77K1 — 'King Turtle' Save the Ocean Limited Edition

The Seiko Prospex SRPF77K1 is part of Seiko's Save the Ocean collection, a series where proceeds support marine conservation organisations. The dial design draws from the view of the ocean as seen through the eyes of the Manta Ray, an endangered species — its colour gradations echo the way sunlight refracts underwater, while the surface pattern evokes waves seen from beneath the sea.

The case shape has earned this model an affectionate nickname among Seiko collectors: the 'Turtle'. Its silhouette, side profile, and rounded caseback resemble a sea turtle's curved shell — a design cue that's become iconic within the Prospex diver lineup. To divers, sea turtles are traditionally seen as symbols of good fortune, and the Turtle case has become one of the most recognisable and well-loved shapes among diving enthusiasts.

Built at 45mm in stainless steel with a sapphire crystal, the SRPF77K1 is rated to 200m water resistance — a genuine diver's tool watch, not just a diver-styled daily piece. The blue silicone strap keeps it comfortable for both underwater use and everyday wear.

At Zimson, the SRPF77K1 comes with full Seiko manufacturer warranty, authentic packaging, and an invoice — as an authorized Seiko retailer in India since 1948.
