The Seiko 5 Sports Skeleton Style SRPJ47K pays tribute to Seiko’s rich design archives, drawing inspiration from the iconic 1970s “Time Sonar” while retaining the beloved SKX case shape known from the 1990s Seiko 5 Sports era.

This modern interpretation showcases the original Time Sonar’s standout features—a translucent dial revealing the rotating day/date discs and a striking red‑orange seconds hand—now refreshed with contemporary materials and engineering.

Built on more than fifty years of Seiko 5 Sports heritage, the SRPJ47K embodies the core principles that define the collection: automatic movement, day‑date functionality, water resistance, a recessed crown, and a durable case‑and‑bracelet construction. With its Hardlex crystal, 10‑bar water resistance, LumiBrite-enhanced visibility, and robust 4R36 automatic calibre offering a 41‑hour power reserve, this watch delivers the reliability and performance Seiko is celebrated for.

What we love about the SRPJ47K. The SRPJ47K perfectly blends retro charm with modern durability. The translucent orange dial is visually captivating, the SKX‑inspired shape feels instantly familiar on the wrist, and the nod to Seiko’s Time Sonar history makes this piece a standout for collectors and everyday wearers alike. It’s a bold, unique Seiko design—full of character, heritage, and unmistakable vintage appeal.
