The Seiko 5 Sports Heritage “Kamen Rider” SRPL03 and SRPL05

Recreating one of the most emblematic Seiko 5 models of the late 1960s.

When relaunched in 2019, the accessible Seiko 5 Sports collection was focused on bringing back the flair of the beloved SKX series, with a diving-oriented look. Since then, the collection has massively expanded, with field models, more compact watches and even GMT versions. We’ve also witnessed the return of historic designs, including that of the very first Seiko 5 Sports from 1968 or a watch taking cues from the Kamen Rider. But today, things go deeper than just a mere inspiration as Seiko brings back the look of the late-1960s 5126-8090 Kamen Rider with two Heritage models, the SRPL03 and SRPL05.

While the brand has already recreated the look of the original 1968 Seiko 5 Sports with the limited edition SRPK17, it had yet to bring back one of the most emblematic models in this collection in a faithful way. Sure, we’ve seen the “Kamen Rider” already used a source of inspiration for a limited edition model – the SRPJ91 – but it was mostly a classic SKX series with a different dial and bezel insert. Today, Seiko goes the extra mile and brings a duo of models with identical cases, dials and bracelets.

With the SRPL03 and SRPL05, Seiko releases a new design with a case that mimics the look of the original Seiko 5 Sports 5126-8090 Kamen Rider. The old model strongly inspired the shape, yet updated to modern proportions and materials. That being said, these two new watches have a compact case of 38.5mm in diameter, with a short lug-to-lug measurement of 44.8mm. The rest is classic 5 Sports series, with a crown (barely visible) at 4 o’clock, a Hardlex mineral glass on top, a rotating bezel with a silver-toned (like the original) metallic insert and a screwed back. Water-resistance is comfortable, as rated at 100m (compared to 70m in the past). The boxy shape certainly brings a 1960s-1970s vibe that will please fans of the brand.

The dial is, once again, strongly inspired by the original watches. The SRPL03 has a silver brushed dial while the SRPL05 relies on a matte black surface. Like the original, there’s a graphic minute track with blocks and baton markers with lume insert, straight hands and a red lollipop seconds hands. References to the past are strong everywhere, with an oddly shaped day-date window and a Sports mention in light blue. Even the original Seiko 5 logo has been recreated for the occasion.

The heritage inspiration doesn’t stop there, as Seiko also brings back the single-link stainless steel bracelet to this duo of models. Fully brushed on the top, its look certainly participates in the overall appeal. It’s closed by a folding clasp with push button release. Also included in the box is a retro rally-styled black leather strap.

No surprises under the dial, as the Seiko 5 Sports SRPL03 and SRPL05 are powered by the trusted Calibre 4R36. This automatic movement runs at a 3Hz frequency, stores about 41 hours of power reserve and includes a hacking function. It’s hidden under a solid back with dedicated engravings.

Released in a limited run of 9,999 pieces per colourway, the Kamen Rider-inspired Seiko 5 Sports Heritage SRPL03 and SRPL05 will be available in July 2024 and priced at EUR 460 or GPB 400. For more details, please visit

  1. what is seiko trying to do…bring back affordable watches that people want to buy for a change? i’m impressed with this offering, something i can’t say about most of the misshapen half-attempts at ‘interpretations’ of 1960s/70s classics of theirs from the days they knew how to make watches without a half-dozen misalignments in each one. dare i cheer them on to become a valued watch maker again?
