The Seiko Prospex Save the Ocean King Samurai SRPF79K showcases Seiko’s long‑standing commitment to precision craftsmanship, adventure‑ready durability, and meaningful environmental initiatives. Part of the acclaimed Save the Ocean collection, this special‑edition timepiece draws inspiration from the underwater world through the eyes of the endangered manta ray. Its stunning blue gradient dial mirrors the shifting light and wave patterns seen from 5 metres beneath the surface, making the SRPF79K not only visually captivating but also deeply symbolic.

Seiko proudly supports marine conservation by donating a portion of proceeds from all Save the Ocean models, reinforcing the brand’s heritage of innovation with purpose.

 Powered by the reliable 4R35 automatic movement with a 41‑hour power reserve, the Prospex diver SRPF79K features a robust 43.8 mm stainless‑steel case with ceramic bezel, sapphire crystal with magnifier, and a comfortable silicone strap built for real‑world exploration. With 200 m water resistance, LumiBrite visibility, a screw‑down crown, and unidirectional bezel, the SRPF79K is engineered to uphold Seiko’s legendary dive‑watch standards—first set in 1965 and continuously evolving ever since. Loved by collectors, its angular case earns the nickname “Samurai,” echoing the sharp, deliberate lines reminiscent of a traditional Japanese sword strike. Presented in a special Save the Ocean box, this model perfectly blends heritage, performance, and purpose‑driven design.

What we love about the Seiko Prospex Save the Ocean King Samurai SRPF79K: The dial is truly the star—its manta‑ray‑inspired blue gradient brings the ocean to your wrist in a way only Seiko can achieve. Combined with the iconic Samurai case and Prospex‑level reliability, the SRPF79K stands out as a meaningful, rugged, and beautifully executed diver that feels special every time you wear it.
