Seiko 5 Sports 38mm SRPK31K

The Seiko 5 Sports SKX Series SRPK31K Men’s Watch is a modern revival of one of Seiko’s most loved designs, deeply rooted in the brand’s unmatched heritage of reliability, durability, and mechanical excellence. First introduced in the 1990s, the original SKX Seiko 5 Sports watches refined the classic Seiko tool watches of the 1960s by improving water resistance, strengthening crystals, and enhancing legibility with luminous hands and hour markers.

Those same practical, everyday values remain central to today’s Seiko 5 Sports collection. Responding to strong demand from Seiko enthusiasts, the SRPK31K reintroduces the popular mid‑sized SKX format, honouring decades of design evolution while delivering modern comfort and wearability.

This contemporary reinterpretation draws its colour inspiration from mid‑sized Seiko 5 Sports quartz divers released in the 1980s, giving the watch a distinctive vintage‑inspired character. The ivory dial, paired with a unidirectional rotating bezel, delivers standout personality while maintaining excellent legibility thanks to LumiBrite‑coated hands and indexes. True to the original SKX design, the case measures 38mm in diameter, now refined with a slimmer profile for enhanced everyday wear. A redesigned three‑row stainless steel bracelet improves comfort and balance, reinforcing the watch’s suitability for active, daily use while retaining its rugged sports‑watch DNA.

Powering the SRPK31K is Seiko’s trusted in‑house Calibre 4R36 automatic movement, offering a 41‑hour power reserve, day‑date display, and stop‑seconds functionality for precise time setting. With 10‑bar water resistance, a see‑through case back, and Seiko’s durable Hardlex crystal, this watch is built to withstand real‑world wear—just as the original Seiko 5 was intended. As with every Seiko 5 Sports model, it proudly embodies the five defining principles of the collection: automatic movement, day‑date functionality, water resistance, a recessed crown, and a durable case and bracelet—values that have earned Seiko global trust for more than fifty years.

What we love about the Seiko 5 Sports SRPK31K is its perfect balance of heritage and modern practicality. The return to the highly wearable 38mm SKX case, combined with the unique ivory colourway and proven Seiko automatic movement, makes this watch feel both nostalgic and refreshingly current. Robust, comfortable, and unmistakably Seiko, it’s a timepiece designed to be worn every day and relied upon for years to come.
