Its dial takes cues from Masked Rider 1’s helmet, while the strap lining and caseback carry further character references. Seiko Malaysia’s regional listing identifies the watch as SRPJ91K1 and supplies the detailed dimensions and specifications below.
What is the Seiko SRPJ91 Masked Rider watch?
Seiko describes the SRPJ91 as a Seiko 5 Sports 55th-anniversary Masked Rider Limited Edition. It is an updated take on the watch associated with Takeshi Hongo in the manufacturer’s collaboration story, which places the original Masked Rider television program’s first broadcast in 1971. Seiko’s character summary also names Hongo and Hayato Ichimonji. Seiko’s official collaboration page

What does the Masked Rider design refer to?
Helmet-inspired dial
Seiko says the dial’s color and pattern were inspired by Masked Rider 1’s helmet. This is the most prominent character reference on the watch itself. Seiko Watch Corporation

Scarf-inspired strap lining
The lining of the calf-leather strap evokes the character’s red scarf, adding a reference that is less visible when the watch is worn.
Tachibana Racing caseback
The see-through glass caseback displays a Tachibana Racing logo, along with the limited-edition marking and an individual serial number. The caseback is therefore both a view of the movement and a location for the collaboration and edition details.
Seiko SRPJ91 specifications
The following figures come from the Seiko Malaysia-operated boutique’s SRPJ91K1 listing. They are regional listing specifications, rather than a specification table reproduced from Seiko’s global collaboration page. Seiko Malaysia boutique
| Specification | SRPJ91K1 listing |
|---|---|
| Movement | Caliber 4R36; automatic with manual winding |
| Jewels | 24 |
| Power reserve | Approximately 41 hours |
| Case material | Stainless steel |
| Crystal | Curved Hardlex |
| Strap | Calf leather |
| Display | Day and date |
| Water resistance | 10 bar |
| Case diameter | 42.5 mm |
| Case thickness | 13.4 mm |
| Lug-to-lug | 46 mm |
| Weight | 94.0 g |
The 10 bar water-resistance rating is the listed specification; it does not, by itself, establish that the watch is a certified dive watch. The listing does not state a lug width, so strap compatibility should be confirmed rather than inferred from the case dimensions.
Is the Seiko SRPJ91 still available?
Availability depends on market, seller, and date. When accessed, the Seiko Malaysia boutique page showed RM2,200 and “Out of stock.” That is a snapshot of one Malaysia listing, not current worldwide inventory, a resale-value estimate, or evidence of Amazon stock. Seiko Malaysia boutique listing
Because SRPJ91 is a limited 2023 release, a listing search for “Seiko SRPJ91K1 Masked Rider Limited Edition” may be more useful than expecting routine new stock. Before buying, check the seller and authenticity, the watch’s condition, the price, and whether the special box and papers are included. The available sources do not establish a fair secondary-market price or verify a particular current listing.
What makes it different from a regular Seiko 5 Sports?
The distinction established by Seiko is primarily the collaboration treatment and limited production: helmet-inspired dial detailing, scarf-referencing strap lining, Tachibana Racing caseback artwork, and a 4,000-piece edition. The listed movement and core technical specifications are the 4R36-based configuration shown above; limited-edition status is not evidence of superior performance. Seiko Malaysia lists a calf-leather strap and the case dimensions, but no specific strap width.
