Seiko Prospex King Turtle Diver's Watch 45mm- SRPF77

Reference Number: SRPF77

Prospex Sea Save the Ocean Special Edition

The Seiko Prospex King Turtle SRPF77 is a standout Save the Ocean special edition, honouring Seiko’s ongoing commitment to marine conservation. Its captivating blue dial is inspired by the underwater view seen by endangered manta rays at around five metres deep, with sunlit gradients and wave‑like textures symbolising the beauty of the ocean from below.

Seiko donates proceeds from Save the Ocean models to organisations dedicated to protecting marine life, making this timepiece meaningful as well as visually striking.

The iconic “Turtle” case shape—named by fans for its curved, shell‑like silhouette—offers exceptional comfort and has long been treasured by diving enthusiasts. Powered by the dependable 4R36 automatic movement with a 41‑hour reserve, this King Turtle includes upgraded features such as a sapphire crystal with magnifier, ceramic bezel insert, LumiBrite across dial and bezel markers, and a robust 200m water resistance. With its silicone strap, unidirectional bezel, and screw‑down crown, it reflects Seiko’s decades of innovation since creating Japan’s first diver’s watch in 1965.
