SEIKO PROSPEX SRPH75K1 ANTARCTICA SAVE THE OCEAN SPECIAL EDITION MEN WATCH

Seiko Prospex SRPH75K1 — Antarctica Save the Ocean Special Edition

The Seiko Prospex SRPH75K1 is a Save the Ocean Special Edition inspired by Antarctica — the frozen continent whose ice shelves and ecosystems are among the most directly affected by the ocean warming that Seiko Prospex's Save the Ocean initiative exists to address. The blue dial carries the design language of the Antarctic ocean environment, and the Special Edition designation connects every purchase to Seiko Prospex's marine conservation commitments. At 42.4mm on a silver stainless steel bracelet, this is the most accessible Save the Ocean edition in the Prospex lineup at this price point, with the full Diver's 200M specification and a day-date display that makes it a practical everyday watch as well as a purposeful collector's piece.

Powered by the in-house 4R36 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPH75K1 delivers the full Prospex diver's specification — Diver's 200M water resistance, unidirectional rotating bezel, and screw-down crown. The Hardlex crystal protects the blue dial through active daily use, and Lumibrite on the hands and hour markers ensures readability at depth and in low light. The day-date display adds everyday practicality for a watch designed to be worn beyond the dive. Presented with a special edition box.

Why You'll Love It

The SRPH75K1 is the Save the Ocean for the buyer who wants the conservation narrative and the Prospex diver specification at the most accessible price point in the Save the Ocean lineup. The Antarctica theme gives it a specific and compelling environmental reference — the Southern Ocean and its ice systems are the focal point of much of what is at stake in marine conservation, and wearing a watch that connects to that narrative is a statement of intent that does not require a premium price. The 4R36 calibre is one of Seiko's most proven automatic movements, the Diver's 200M rating means it handles the water, and the day-date display makes it genuinely functional for daily wear. A Save the Ocean Special Edition that earns its purpose at a price that opens the initiative to a wider audience.

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 conservation partnerships, and the environmental message behind the purchase. The SRPH75K1 Antarctica edition connects that brief to the frozen ocean systems at the southern extremes of the world — the region most acutely affected by the conditions Save the Ocean aims to address.

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 SRPH75K1 carries that legacy forward with a commitment that extends beyond the watch itself.
