SEIKO PROSPEX SRPF79K1 SAVE THE OCEAN ‘KING SAMURAI’ DIVERS AUTOMATIC MEN WATCH

Seiko Prospex SRPF79K1 — Save the Ocean Automatic Diver's Watch

The Seiko Prospex SRPF79K1 is a Save the Ocean Special Edition — part of Seiko Prospex's ongoing commitment to marine conservation, with a portion of proceeds supporting ocean protection efforts. The watch is built on the Samurai case, with the angular, blade-like design that the Samurai name references, and the blue dial and matching blue silicone strap connect it directly to the ocean environment it is designed to protect. Save the Ocean editions carry the same professional Prospex diver's specification as the standard lineup — Diver's 200M water resistance, ceramic unidirectional rotating bezel, and screw-down crown — with a design narrative that reinforces the purpose behind the purchase.

Powered by the in-house 4R35 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPF79K1 is mechanically dependable and practically complete. The sapphire crystal protects the blue dial, Lumibrite on the hands and hour markers delivers legibility at depth and in low light, and the screw-down crown reinforces the Diver's 200M water seal. At 43.8mm and an exceptionally slim 12.8mm profile, it is one of the most comfortable-wearing Diver's 200M automatics in the Prospex Save the Ocean lineup — and the blue silicone strap keeps it ocean-ready from dial to clasp.

Why You'll Love It

The SRPF79K1 is the Seiko Prospex diver for those who want the Samurai case shape with a purpose behind the colour. The Save the Ocean designation connects the watch to Seiko's marine conservation commitments — this is not a colour scheme, it is a statement of intent. The Samurai's angular design gives it a distinctive wrist presence that stands apart from the Turtle and Sumo, and the 12.8mm slim profile makes it more comfortable to wear all day than the 43.8mm diameter suggests. The ceramic bezel is virtually unscratchable through daily use, the sapphire crystal keeps the dial pristine, and the blue silicone strap creates a dial-to-strap coherence that reinforces the ocean narrative with every glance.

About Seiko Save the Ocean

Seiko's Save the Ocean initiative reflects the Prospex brand's commitment to the marine environment that its dive watches are built to perform in. Save the Ocean Special Editions carry a design brief that references the ocean directly — in the dial colour, the strap choice, and the conservation partnerships that the initiative supports. The SRPF79K1 is one expression of that brief: a professional diver's watch with an ocean-connected aesthetic and a clear statement of purpose behind the purchase.

The Seiko Prospex Story

Prospex is a combination of the words "Professional" and "Specifications." Seiko Prospex timepieces are designed to be practical, reliable, and durable — built to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. Since 1965, when Seiko created Japan's first diver's watch, the Prospex dive line has stood for underwater precision and reliability. The SRPF79K1 carries that sixty-year legacy forward with a commitment that extends beyond the watch itself.
