As a lifelong admirer of Seiko’s dive watches, a few announcements have stirred my enthusiasm, like the unveiling of the Seiko Prospex 60th Anniversary Limited Editions in 2025. This is more than just another release—it celebrates six decades of innovation, adventure, and unshakable Japanese craftsmanship.
To understand why these three new limited-edition timepieces matter, you must step back to a humble but pivotal moment in Seiko’s history.
A Legacy Born From the Depths – The Origin of Prospex
In 1965, Seiko received a letter from a professional Japanese diver who revealed a pressing issue: the watches he wore during deep-sea dives failed under pressure. It was a call to action that Seiko didn’t ignore.
The result? The creation of Japan’s first-ever diver’s watch—the now-iconic Seiko 62MAS. Its automatic movement and 150-meter water resistance marked the birth of a legacy that would shape the world of professional dive watches for decades.
Fast-forward 60 years, and Seiko commemorates this journey with three masterfully crafted timepieces that nod to its past while pushing the boundaries of modern horology.
Let’s dive into the 2025 Seiko Prospex 60th Anniversary collection.
1. Seiko Prospex 1965 Heritage Diver’s Watch – Seiko Diver’s Watch 60th Anniversary Limited Edition
- Price: Approx. £1,600
- Limited to: 6,000 pieces
- Movement: In-house Calibre 6R55 (72-hour power reserve)
- Water Resistance: 300 meters
- Design Note: “The Great Wave off Kanagawa” textured dial
- May 2025 Release
This model directly homages the 1965 62MAS, the original diver that started it all. But this isn’t a mere reissue—it’s a modern reimagination that brings vintage charm into the 21st century.
The dial is where this piece truly sings. Inspired by Hokusai’s ‘The Great Wave’, the crisp white texture resembles swirling sea foam, offering a poetic nod to Seiko’s marine heritage and Japan’s artistic soul.
With a robust 300m water resistance and Seiko’s newly enhanced 6R55 movement, this diver is built for both the deep and the everyday. The new short-pitch bracelet with a micro-adjustable clasp ensures comfort, even over a wetsuit.

Watch Blogger Take:
This isn’t just a reissue—it’s a love letter to Seiko purists. For anyone who’s always admired the 62MAS but wanted modern specs, this is a dream come true.
2. Seiko Prospex 1968 Heritage Diver’s GMT – Dual-Time Depths
- Price: Approx. £1,600
- Limited to: 6,000 pieces
- Movement: In-house Calibre 6R54 (GMT function)
- Water Resistance: 200 meters
- Dial: Deep ocean blue with ‘Great Wave’ motif
- Jun 2025 Release
The second tribute pays homage to the 1968 Hi-Beat Diver, a groundbreaking model in Seiko’s evolution that introduced a monobloc case and 300-meter water resistance. While this 2025 model includes a practical GMT complication for globetrotters, its styling still echoes the diver’s tool-watch roots.

The dial’s deep blue wave pattern adds a sense of layered motion, like looking into an ocean abyss. Combined with the GMT hand, this piece feels like it’s been built for modern adventurers who cross time zones as often as currents.
Like its 1965 sibling, the GMT edition also features the micro-adjustable bracelet, a first for the Prospex line, and a welcome touch for comfort and wearability.
Watch Blogger Take:For collectors torn between nostalgia and practicality, this GMT bridges both worlds. It’s perfect for those who dive—or dream—across time zones.
3. Seiko Prospex Marinemaster Professional
Seiko Diver’s Watch 60th Anniversary Limited Edition
- Price: Approx. £4,130
- Limited to: 600 pieces
- Movement: In-house 8L35 (Three-day power reserve)
- Water Resistance: 600 meters
- Material: Titanium case with diamond-like carbon coating
- Release: Available in July 2025
Now we come to the apex predator of the deep—the Marinemaster’ Shinkai’, the most technologically advanced Prospex model to date. This watch is a technical marvel crafted at the prestigious Shizukuishi Watch Studio, home of Seiko’s finest mechanical calibers.
“Shinkai,” which translates to deep sea, is more than a name. It evokes Japan’s enduring fascination with the mysterious, unreachable depths. The dial’s layered, semi-transparent blue design simulates the darkness and pressure of the ocean trench, pulling you into the abyss every time you glance at your wrist.
Model: Seiko Prospex Marinemaster Professional Seiko Diver’s Watch 60th Anniversary Limited Edition SLA081
With a massive 600-meter water resistance, lightweight titanium case, and a diamond-like carbon (DLC) coating for extreme scratch resistance, this isn’t just a collector’s piece—it’s a tool built for serious professionals.
📌 Watch Blogger Take:
The Shinkai is the crown jewel of this anniversary release. It’s bold, technical, and emotionally resonant. This is the one for those who crave something rare, robust, and deeply symbolic.
Which Seiko 60th Anniversary Model Is Right For You?

If you love vintage reissues, the 1965 diver hits all the right notes.
Need modern functionality for travel? The 1968 GMT is your go-to.
Craving a collector’s grail with technical chops? Shinkai, without a doubt.
Design Depth: The “Great Wave” Motif
The recurring theme of Hokusai’s Great Wave is perhaps this collection’s most emotionally resonant aspect. By invoking this iconic Japanese artwork, Seiko merges art with engineering, making each piece not just a tool but a wearable story.
This wave motif connects all three watches—white on the 1965 model, deep blue on 1968, and abstract on the Shinkai—like currents of a single ocean, flowing from one generation to the next.
The Collector’s Perspective
From a collector’s standpoint, these models aren’t just timekeepers—they’re time capsules. The limited production numbers, in-house movements, and heritage-driven design virtually guarantee that these pieces will retain, if not grow, value over time.
For those who missed out on previous anniversaries, like the 55th Anniversary SLA037, this 60th set offers another shot at securing a landmark Prospex piece.
Final Thoughts – Wearing a Piece of Seiko History
As someone who’s followed Prospex’s evolution from the 62MAS to today’s Marinemaster, this collection feels like the perfect synthesis of legacy and innovation.
Whether you’re a deep-sea diver, a desk diver, or simply someone who appreciates mechanical mastery and Japanese artistry, the Seiko Prospex 60th Anniversary models offer something profound. They’re not just watches. They’re stories, milestones, and testaments to the enduring spirit of exploration.
