Case #152 — Seiko Prospex “Save the Ocean” Ref. SRPD11

Status: Active Investigation
Condition: Excellent Pre-Owned
Scope: Full Kit (Box, Papers, Tags, Rare Matching Bracelet)

🔎 Case Notes

The Seiko Prospex SRPD11 “Save the Ocean” is one of the most visually striking modern Prospex releases — a diver that blends rugged reliability with an ocean-inspired design language that has become a favorite among enthusiasts.

The first thing that pulls you in is the deep blue, texture-rich dial — a layered wave motif designed to mimic the surface of Antarctic waters. The gradient ranges from near-black at the top to glacial blue at the bottom, creating a sense of depth and motion that feels alive on the wrist.

Adding to its collectibility, this example includes the rare OEM matching bracelet, which was produced in limited numbers compared to the standard strap options. It completes the watch with a more elevated, integrated feel while maintaining the classic Seiko diver character.

This SRPD11 comes as a full kit and is in excellent pre-owned condition, with crisp case lines, a clean dial, and a bright bezel. Light, natural wear is present only on close inspection, consistent with a watch that has been carefully enjoyed, not overused.

🌊 The Save the Ocean Legacy

The Save the Ocean collection is one of Seiko’s most meaningful and widely celebrated programs. Created in partnership with oceanographer Fabien Cousteau (grandson of Jacques Cousteau), each release is designed to raise awareness and support marine conservation efforts across the globe.

The SRPD11’s design reflects this mission:

• Wave-pattern dial inspired by the Antarctic Ocean.

• Gradient coloration representing the descent from light surface waters to deeper, darker currents.

• Blue-and-black bezel echoing the shadows and light that shift through the sea.

A portion of the proceeds from each “Save the Ocean” model directly supports marine protection projects, giving the watch a purpose beyond aesthetics and mechanics.

Over time, collectors have embraced Save the Ocean references as some of Seiko’s most emotionally resonant and visually compelling modern divers — and the SRPD11 sits high on that list.

🌟 Collector Provenance

The SRPD11 is highly regarded for its dial, limited bracelet availability, and connection to a global environmental initiative. Full-kit examples — especially with the rare OEM bracelet — remain the most sought-after and best-preserved representations of the reference.

🌟 Celebrity Provenance

The Save the Ocean series has been featured across numerous conservation events and worn by environmental advocates, scuba professionals, documentary hosts, and marine researchers linked to ocean-protection organizations. While not tied to a single celebrity, the line has earned a strong following among those passionate about marine preservation.
