The Seiko 5 Sports SRPL05 is the black-dial half of Seiko’s Heritage Design Re-creation limited pair — a modern take on late-1960s / early-1970s Seiko 5 sports watches nicknamed for the “Kamen Rider” era look. You get a compact cushion case, a matte black dial with a red lollipop seconds hand, and the workhorse Caliber 4R36 automatic with day-date, hacking and hand-winding.
At 38.5mm across and only about 44.8mm lug-to-lug, the SRPL05 wears smaller than many current Seiko 5 Sports models while still reading as a proper sports watch thanks to the boxy cushion silhouette and external rotating bezel. 100m water resistance, Hardlex crystal and a single-link steel bracelet make it realistic for daily wear; an extra black leather strap is included when you want a softer look.
Why the SRPL05 stands out
- Black dial presence — matte black face with silver baton indices and LumiBrite on hands and markers for low-light readability.
- Wearable heritage size — 38.5mm diameter, ~12.4mm thick, short lugs that suit more wrists than oversized modern divers.
- Practical automatic — Caliber 4R36: 24 jewels, ~41-hour power reserve, manual wind, hacking seconds, day-date at 3 o’clock.
- Sports package — recessed crown at 4 o’clock, metallic bezel insert, screwed solid case back numbered as limited edition.
- Two straps in the box — brushed single-link steel bracelet (20mm lug width, three-fold clasp) plus a black leather strap for quick swaps.
- Limited run — 9,999 pieces for this colourway, case-back marked Limited Edition with serial numbering.
Who it suits
Choose the SRPL05 if you want a compact black Seiko 5 Sports automatic that nods to vintage Japanese sports watches without a 42mm+ footprint. It works as a daily beater, a travel piece, or a quieter alternative to busier dive-style Seiko 5 models. The silver-dial sibling is the SRPL03 if you prefer a brighter face.

SRPL05 vs SRPL03
Both share the same case, movement, crystal, water resistance and strap package. The main difference is the dial: SRPL05 is matte black; SRPL03 is brushed silver. Pick black for a stealthier everyday look, silver if you want more light play on the dial.
Frequently asked questions
What is the Seiko 5 Sports SRPL05?
It is a limited-edition Seiko 5 Sports automatic that recreates a classic late-1960s / early-1970s cushion-case sports design. The SRPL05 is the black-dial version; production is capped at 9,999 pieces for this colourway.
What movement does the SRPL05 use?
Seiko Caliber 4R36 — an automatic mechanical movement with 24 jewels, about 41 hours of power reserve, hand-winding and hacking seconds. It is not solar or quartz.
What is the case size of the SRPL05?
About 38.5mm in diameter, 12.4mm thick and 44.8mm lug-to-lug, with a 20mm lug width. It wears more compact than many modern Seiko 5 Sports references.
Is the SRPL05 a dive watch?
It is a sports watch with 100m water resistance and a rotating bezel. That is fine for swimming and daily splash; it is not an ISO 6425 professional diver. Rinse after salt water and avoid operating the crown underwater.
Does the SRPL05 come with two straps?
Yes — Seiko supplies a stainless steel bracelet and an additional black leather strap with this heritage re-creation pair, so you can change the look without buying aftermarket parts first.
