SEIKO PROSPEX SRPG57K1 ANTARCTICA MONSTER SPECIAL EDITION MEN WATCH

Seiko Prospex SRPG57K1 — Antarctica Monster Save the Ocean Special Edition

The Seiko Prospex SRPG57K1 is a Save the Ocean Special Edition built on the Monster case — the wide, distinctive dive watch silhouette that earned its collector nickname from the bezel design said to resemble an open monster's mouth. The Antarctica theme connects this edition to the world's largest marine sanctuary: the light blue dial references the glacial landscape of the Southern Ocean, and a portion of proceeds supports Seiko Prospex's marine conservation commitments. At 42.4mm on a silver stainless steel bracelet, this is the most accessible Save the Ocean Monster in the Prospex lineup, combining the distinctive Monster case character with a design narrative that connects the watch to the environment it is built to protect.

Powered by the in-house 4R36 automatic calibre with hand-winding capability and a 41-hour power reserve, the SRPG57K1 delivers the full Prospex diver's specification — Diver's 200M water resistance, unidirectional rotating bezel, and screw-down crown. The Hardlex crystal protects the light 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. Presented with a Save the Ocean special edition box.

Why You'll Love It

The SRPG57K1 is the Save the Ocean for the buyer who wants the Monster case shape with a purpose behind the colour. The Monster has a character that no other Prospex diver shares — the bezel design is genuinely distinctive and the wide 42.4mm case wears with a visual authority that the Turtle and Samurai case shapes approach differently. The Antarctica light blue dial gives it an environmental narrative that is specific and meaningful: the Southern Ocean, the glacial ice systems, and the marine ecosystem that depends on them are exactly what Seiko's Save the Ocean initiative exists to address. The 4R36 calibre is proven and reliable, the Diver's 200M rating is fully professional-spec, and the day-date display makes it genuinely functional for all-day daily wear.

About the Monster

The "Monster" nickname — given by Seiko collectors rather than Seiko itself — refers to the distinctive unidirectional rotating bezel design whose serrated inner edge is said to resemble the teeth of an open monster's mouth. The case shape has built a devoted following for its combination of bold visual character, substantial wrist presence at 42.4mm, and exceptional daily wearability. The SRPG57K1 brings that Monster character to a Save the Ocean context, pairing the distinctive case with a light blue dial that connects to the Antarctic marine environment the edition supports.

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 SRPG57K1 carries that legacy forward with a commitment that extends beyond the watch itself.
