Seiko 5 Sports SRPL77K1 — SKX Series Automatic Men's Watch

The Seiko 5 Sports SRPL77K1 is a new addition to the New Colour Collection — a modern reinterpretation of the fan-favourite SKX style first made popular in 1996, with a design DNA that stretches over five decades of Seiko 5 Sports heritage. The colour scheme is designed specifically to complement modern street fashion: the blue dial and matching deep blue bezel are inspired by the tones of stonewashed indigo denim — one of the most enduring and versatile materials in contemporary menswear. The result is a watch that feels at home with the casual tailoring, layered streetwear, and relaxed-smart dressing that define urban everyday style.

At a compact 38mm this is the more approachable, wrist-friendly expression of the SKX design — a size that moves naturally with the body, fits under a cuff without bulk, and wears comfortably all day. Powered by the in-house 4R36 automatic calibre with hand-winding capability, see-through caseback, and a 41-hour power reserve, the SRPL77K1 delivers the complete Seiko 5 Sports specification — automatic, day-date, 100M water resistance, recessed crown, durable case and bracelet — in a package built for daily urban wear.

Why You'll Love It

The SRPL77K1 is the Seiko 5 Sports for the man who wants a sports watch that leads with colour — the stonewashed indigo blue palette is the most wearable of the SKX New Colour Collection variants, as natural with a pair of jeans as it is with a casual jacket or a weekend outfit. The all-blue execution — dial and bezel in matching deep indigo — gives it a visual cohesion that sets it apart from standard blue-dial dive watches, and the SKX silhouette has earned its reputation over nearly three decades as one of the most recognisable and wearable Seiko 5 Sports designs. The 38mm compact case makes this the most accessible size in the range — neat enough for a formal occasion, relaxed enough for everyday wear, and precisely the right size for those who find larger dive-style watches overwhelming. The see-through caseback adds mechanical depth, the 41-hour power reserve handles any long weekend, and all five Seiko 5 Sports credentials are firmly in place. A well-considered, colour-led everyday automatic.

SRPL77K1 vs SRPL79K1 — Blue or Black Denim?

Both models share identical specifications — the same 4R36 calibre, 38mm case, 12.1mm depth, Hardlex crystal, see-through caseback, day-date display, Lumibrite, 100M water resistance, and 41-hour power reserve. The difference is entirely in the dial and bezel colour. The SRPL79K1 has a black denim-inspired dial with gold accent hands — darker, more urban, and the bolder street-style statement. The SRPL77K1 has a blue denim-inspired dial with a matching deep blue bezel — more versatile, more classic, and the natural everyday choice for blue dial enthusiasts. Same SKX character, two completely different moods.

The Seiko 5 Sports Story

Seiko 5 Sports represents over fifty years of reliability, durability, performance, and value. The "5" stands for the five key features present in every Seiko 5 since its introduction: automatic movement, day-date display, water resistance, recessed crown, and a durable case and bracelet. The SKX series, first introduced in 1996, became one of the most beloved Seiko 5 Sports designs in the brand's history — a silhouette that combines sports credentials with everyday wearability. The SRPL77K1 brings that heritage into the New Colour Collection with a dial inspired by the most iconic fabric in modern fashion.
