Seiko partners with streetwear pioneer HUF on a limited-edition 5 Sports Field watch featuring transparent green dials, San Francisco-inspired caseback art, and skate-culture heritage.

Seiko's latest collaboration bridges horology and street culture with the SRPM09 Limited Edition, developed alongside iconic skate brand HUF. Limited to just 7,000 units globally (with 1,000 reserved for Japan as SBSA323), this March 2026 release reimagines Seiko's rugged Field watch lineage through the lens of urban fashion.
Design & Specifications

The 39.4mm stainless steel case maintains the 5 Sports' utilitarian proportions (11.6mm thick, 48.1mm lug-to-lug) but introduces HUF's signature "Green" aesthetic. The semi-transparent dial reveals the day/date wheels beneath, creating a layered visual effect unseen in standard Field models like the SRPG series. An orange-tipped seconds hand provides contrast against the green backdrop, while the 6 o'clock position features subtle "huf" branding.
Protection comes from Seiko's Hardlex crystal and 100m water resistance (10 bar), matching the durability of the base Field watches. The exhibition caseback
undergoes a thematic transformation: tinted green to match the dial and etched with San Francisco skyline graphics, honoring HUF's 2002 origins in the city.
Movement & Performance
Powering the SRPM09 is Seiko's workhorse Caliber 4R36 automatic movement - the same engine driving the standard 5 Sports lineup. This facilitates direct comparisons: both share the 41-hour power reserve, manual winding capability, and hacking seconds function. No performance upgrades differentiate it mechanically from the $250-$350 Field models, positioning the collaboration as primarily an aesthetic evolution.
Streetwear Heritage & Target Audience
Founded by pro skater Keith Hufnagel, HUF evolved from a boutique shop to a global streetwear authority. This collab targets collectors at the intersection of horology and urban culture - those who value the narrative behind limited editions. The included HUF-branded tin case and cleaning cloth enhance the collectible appeal beyond Seiko's standard packaging.
Compared to previous streetwatch collaborations like Timex's Todd Snyder editions, Seiko leverages its robust tool-watch credibility while HUF contributes subculture authenticity. At an anticipated $400-$500 price point (based on prior limited 5 Sports models), it commands a premium over standard Field watches but remains accessible next to luxury streetwear collabs from brands like Tag Heuer.
Verdict
This isn't a tool-watch revolution, but a thoughtful design exercise merging Seiko's engineering with HUF's aesthetic legacy. For streetwear enthusiasts, the transparent dial and SF-themed caseback offer unique storytelling. Traditional Field watch buyers might prefer standard models for value, but collectors seeking limited-run pieces with cultural resonance will find the SRPM09 compelling. Just 7,000 units ensures exclusivity, though availability constraints may challenge eager buyers come March 2026.
