From SKX Roots To Street Style: Seiko SRPL77 & SRPL79 Announced
Seiko has just unveiled two exciting new additions to its Seiko 5 Sports collection, continuing the legacy of its legendary SKX dive watch from the 1990s. The new references — SRPL77 and SRPL79 — combine the iconic SKX design with a fresh twist inspired by street fashion and denim style, making them perfect for modern, everyday wear.

Compact SKX-Style Case for Enhanced Wearability
The new Seiko SRPL77 and SRPL79 both feature the instantly recognizable SKX-style case, now reimagined in a more compact and wearable form. Measuring 38 mm in diameter, 12.10 mm thick, and 44.20 mm lug-to-lug, these models offer a balanced wrist presence, ideal for a wide range of wrist sizes.

The stainless steel case alternates between polished and brushed finishes for a dynamic look, and comes equipped with a unidirectional rotating bezel featuring an aluminum insert and diving scale. Both models use Seiko’s proprietary Hardlex crystal, a screw-down see-through caseback, and offer a 100-meter water resistance, making them versatile companions for daily adventures.
Denim-Inspired Dials with Sunray Finish
In line with their urban fashion inspiration, the SRPL77 sports a deep blue dial and bezel reminiscent of classic blue denim, while the SRPL79 features a dark grey palette evoking stonewashed black denim.

Both dials exhibit a beautiful sunray effect, with applied hour markers and sword-style hands finished in silver (SRPL77) or gold (SRPL79) tones. All elements are coated with Seiko’s Lumibrite for exceptional visibility in low-light conditions. A prominent lollipop-style seconds hand, a day-date window at 3 o’clock, and branding elements placed at 12 and 6 o’clock complete the classic Seiko 5 layout.
Reliable Calibre 4R36 Movement
Powering these new models is the tried-and-true Calibre 4R36 automatic movement, a 24-jewel engine operating at 21,600 vibrations per hour (3 Hz). It offers manual winding, hacking seconds, and delivers a 41-hour power reserve — a trusted movement known for reliability and ease of service.
Stainless Steel Bracelet & Availability
Both the Seiko SRPL77 and SRPL79 come fitted with a 3-link stainless steel bracelet, complete with a signed folding clasp for secure wear. These watches are scheduled for release in August 2025 with an attractive retail price of GBP 290.

Final Thoughts
With the SRPL77 and SRPL79, Seiko continues to honor the spirit of the SKX line while adapting it for today’s style-savvy watch enthusiasts. These denim-inspired designs, wearable dimensions, and dependable specs make them standout choices for those looking for a blend of nostalgia, fashion, and everyday reliability.
