What’s new in Seiko’s 145th-anniversary divers?

Seiko marked its 145th anniversary with new Prospex divers

Seiko celebrated 145 years with new additions to its Prospex lineup, including limited-edition models pulled from the brand’s watchmaking past. The key theme across these anniversary launches is a return to classic dive-watch cues—updated for today while staying recognizable to long-time Seiko fans.

Two anniversaries, two diver stories

The anniversary coverage includes two related announcements:

• A pair of blue-bezel Prospex divers presented as pulled “straight from the archives,” positioned as part of the 145th celebration.
• A separate 145th-anniversary limited-edition Prospex “Samurai” diver that features a “Silverstone” dial with “Seiko Blue” accents and a 200-meter water-resistance rating.

Limited availability and what it signals

The “Shiro-neri” Presage story is separate, but the divers underscore Seiko’s approach to its milestone: limited production runs that appeal to collectors and enthusiasts who track archive-inspired colorways and references.

In practical terms, buyers looking for the most distinctive anniversary models will need to move quickly when these releases land, especially because anniversary pieces are typically treated as finite offerings.

Why anniversary divers matter to buyers

Dive watches are one of Seiko’s signature categories. Anniversary editions matter because they often combine strong brand identity (design language, water-resistance credibility, and tool-watch heritage) with collectible scarcity. For people shopping for a “next” daily-wear watch, these Prospex releases are also a way to buy into Seiko’s historical design vocabulary without settling for a basic reissue.

Overall, Seiko’s 145th anniversary positioning makes the Prospex divers feel like both celebration and collector-ready product—particularly for fans drawn to blue accents and archival inspiration.
