The Seiko Prospex King Turtle SRPE33K is a captivating Special Edition diver’s watch from Seiko’s renowned Save the Ocean collection, combining the brand’s rich dive‑watch heritage with meaningful ocean‑conservation purpose. Its mesmerising blue dial is inspired by the underwater world as seen through the eyes of the endangered manta ray at a depth of five metres. The subtle wave patterns and luminous gradients echo sunlight refracting through the sea, creating a dial that is both artistic and deeply symbolic.

This model is built to Seiko’s professional diving standards, featuring a black ceramic bezel, sapphire crystal with magnifier, stainless‑steel construction, and LumiBrite across the hands, indexes, and bezel for exceptional legibility.

Powered by the dependable 4R35 automatic movement with a 41‑hour power reserve, the SRPE33K delivers robust performance with a 43.8 mm case, 200 m water resistance, screw‑down crown, secure‑lock clasp, and anti‑reflective coating. Seiko continues its long‑standing commitment to marine preservation by donating a portion of proceeds from Save the Ocean models to conservation organisations worldwide. Although part of the King Turtle lineage, this model is often lovingly nicknamed by enthusiasts as part of the “Samurai” design family thanks to its angular, sword‑like case lines—an aesthetic deeply rooted in Japanese craftsmanship.

What we love about the Seiko Prospex King Samurai SRPE33K: The manta‑ray‑inspired dial is truly breathtaking, offering a unique depth and texture that feels alive on the wrist. Paired with the upgraded materials, ceramic bezel, and trusted Prospex engineering, this King Turtle stands out as one of Seiko’s most visually compelling and meaningful diver’s watches—a perfect blend of heritage, purpose, and everyday durability.
