Fresh hands-on footage has surfaced for the Seiko 5 Sports SRPM09 HUF Limited Edition, offering the clearest real-world look yet at the watch’s standout feature: its “Time Sonar”-inspired translucent green dial. After an initial launch earlier in February, this new video provides a much more accurate sense of how the dial looks outside of polished promotional images—and it’s the kind of design that’s likely to turn heads, especially for collectors who want something different in the accessible Seiko 5 lineup.
What makes the SRPM09 HUF edition immediately distinctive is the layered, semi-transparent “HUF Green” acetate dial. In natural light, the green tones shift and glow, and the dial’s transparency reveals the day and date wheels underneath. That open, mechanical peek-through effect creates a dimensional, almost engineered look that’s uncommon at this price point. Adding to the layered feel, the black horizontal “Automatic” bar and the “huf” logo at 6 o’clock appear to sit above the green surface, giving the dial a floating, three-dimensional character.
The watch comes in a 39.4 mm stainless-steel case with a brushed finish often associated with field-style tool watches. It’s paired with a three-link, oyster-style bracelet for a classic sporty fit. The 48.1 mm lug-to-lug measurement is also shown from practical angles in the hands-on coverage, helping potential buyers judge how it might wear on the wrist even without extensive on-wrist photography.
For contrast, Seiko adds an orange-tipped seconds hand that pops sharply against the lime-green dial. It’s a small touch, but it brings a high-visibility element that makes the entire design feel more purposeful and easier to read at a glance—especially important on such a visually bold dial.
Inside, the SRPM09 is powered by Seiko’s Caliber 4R36 automatic movement, a familiar and proven workhorse in the brand’s affordable mechanical lineup. It beats at 21,600 vph and offers around 41 hours of power reserve. The movement can be viewed through an exhibition case back that’s tinted green and includes a custom San Francisco graphic, reinforcing the collaboration theme and giving the limited edition more personality than a standard production model.
Rarity is part of the appeal here. The Seiko 5 Sports SRPM09 HUF Limited Edition is limited to 7,000 pieces worldwide, with 1,000 units allocated to Japan under the reference SBSA323. Pricing is set around $450 USD (approximately EUR 410), and the watch is expected to release in March 2026.
For anyone searching for a Seiko 5 Sports limited edition that combines streetwear collaboration energy with a retro-futuristic “Time Sonar” dial concept, the SRPM09 HUF edition stands out as one of the more visually adventurous releases in the Seiko 5 range—while still keeping the practical sizing, reliable movement, and everyday-wear format the line is known for.
