ONE PIECE Shinkansen Watch Seto Inland Sea Blue Train Model Limited Edition Wristwatch

The ONE PIECE Shinkansen Watch — Seto Inland Sea Blue Train Model is an officially licensed collaboration timepiece produced by Premico in partnership with Seiko, themed around the "ONE PIECE Shinkansen" — the real-world San'yo Shinkansen train that has been running since April 2025, wrapping a 500-series bullet train in the visual world of ONE PIECE. The Seto Inland Sea Blue model takes its colour from the "せとうちブルー号" — the blue-themed train set that travels the San'yo route between Shin-Osaka and Hakata, running alongside the blue waters of the Seto Inland Sea. The dial translates that journey into watchmaking: the deep Seto Blue across the face, the movement of the train expressed through the chronograph sub-dials, and ONE PIECE characters and motifs woven into the design at every level of detail. The watch arrives in a special box designed to evoke an adventure treasure chest — a direct reference to the treasure-chest imagery at the heart of the ONE PIECE world. Produced by Premico and Seiko, made in Japan. Ships from mid-January 2027.

*Pre-Order's before August 24th: Estimated shipment from mid-January 2027.*

Key Features:

• Seto Inland Sea Blue Dial — "せとうちブルー号" Train Colour: The dial colour is drawn directly from the Seto Inland Sea Blue train — the blue-coloured wrap of the 500-series Shinkansen that runs the San'yo route alongside the Seto Inland Sea. The blue evokes both the train's livery and the sea it runs beside — the same Seto Blue that frames the route between Osaka and Fukuoka and gives the train its name.
• ONE PIECE Shinkansen — Running Since April 2025: The ONE PIECE Shinkansen is a real, operational collaboration between West Japan Railway Company (JR西日本) and the ONE PIECE franchise — a 500-series bullet train wrapped in ONE PIECE character artwork, serving the San'yo Shinkansen line since April 2025. The "せとうちブルー号" is one of the train sets in that collaboration and the direct inspiration for this watch.
• Adventure Treasure Chest Special Box: The watch is delivered in a special box designed to evoke an adventure treasure chest — the central symbol of ONE PIECE's world, the object that Luffy and the Straw Hat Pirates have always been chasing. Display-worthy packaging in keeping with the treasure-hunting spirit of the series.
