Seiko · Family: 5 Sports
The Seiko 5 Sports SRPD55K1 is an entry-level stainless steel automatic with a sunburst blue dial, day/date function, and a fixed coin-edge bezel. It runs the Calibre 4R36, with hacking seconds and manual winding, roughly 41 hours of power reserve. Cazador has zero verified price observations today. Its differential: a genuinely complete mechanical movement — including manual winding, unusual at this price point — inside the Seiko 5 Sports line, globally relaunched in 2019.

In 2019, Seiko globally relaunched its entry-level Seiko 5 line, splitting it into style-driven sub-collections: 5 Sports, 5 Suits, and 5 Street, among others. The SRPD55K1 belongs to the 5 Sports sub-collection, which borrows part of the visual language of Seiko's dive watches — rotating or fixed coin-edge bezels, vivid dial colors — without necessarily carrying the professional dive certification of other Seiko lines.
The mechanical core of this reference is the Calibre 4R36, an evolution of the historic 7S26 found in models like the Seiko SKX007. The main technical difference is that the 4R36 adds hacking seconds (the seconds hand stops when the crown is pulled to set the time) and manual winding, two functions absent from the 7S26. The result is roughly 41 hours of power reserve.
The case, in stainless steel and roughly 42.5mm in diameter, carries a fixed coin-edge bezel with no dive scale — a trait that sets this variant apart from more dive-oriented models within the Seiko 5 Sports range itself. The sunburst blue dial carries a day/date window at 3 o'clock, with the day language varying by market — a detail we don't pin down precisely in this fiche.
The crystal is Hardlex, Seiko's own hardened mineral glass, more impact-resistant than sapphire though more prone to scratching. The factory bracelet is stainless steel, with a fold-over clasp and safety lock.
Rated to 100 meters of water resistance, the SRPD55K1 covers daily wear and splashes, without the technical dive mandate of higher-water-resistance Seiko references. Per the catalog data used for this fiche, the reference remains in active production, within one of the highest-volume lines across the entire brand thanks to its entry-level price paired with a genuinely complete mechanical movement.
Cazador has no verified PricePoint observations for this reference, so we cannot publish a reliable market range.
Yes. Unlike the 7S26 caliber found in earlier Seiko generations, the 4R36 caliber in this reference supports manual winding in addition to automatic winding via the rotor.
Yes. The seconds hand stops when the crown is pulled to set the time, allowing the watch to be synchronized precisely to the second.
It's rated to 100 meters with a fixed coin-edge bezel and no dive scale, so it covers daily wear and splashes but isn't built as a technical dive watch.
No. It's fitted with Hardlex, Seiko's proprietary hardened mineral crystal — more impact-resistant than sapphire but more prone to scratching.
The Calibre 4R36 delivers roughly 41 hours of power reserve on a full wind.
It belongs to the global 2019 relaunch of the Seiko 5 Sports line and remains in active production today.
