Seiko Launched Limited-Edition One Piece Shinkansen Watch: Price, Features and Release Details

Seiko has launched a limited-edition chronograph inspired by Japan’s One Piece-themed Shinkansen bullet train. Officially named the Setouchi Blue Model, the watch celebrates the 50th anniversary of the Sanyo Shinkansen line connecting Shin-Osaka and Hakata .

Orders are open through Premico at ¥76,780 (including consumption tax, roughly $482/£390), with shipping expected to begin in mid-January 2027 . Only 5,000 units will be produced, making this a highly sought-after piece for both anime enthusiasts and watch collectors .

Seiko Launches Limited-Edition One Piece Shinkansen Watch

Seiko launched a limited edition that brings together three iconic Japanese cultural elements: the legendary watchmaker, the world’s first high-speed railway, and the beloved One Piece anime franchise .

The watch draws inspiration from the “Setouchi Blue” train—one of three One Piece-themed bullet trains launched by JR West in April 2025 to celebrate the Sanyo Shinkansen’s 50th anniversary . The other two trains feature designs based on characters Luffy and Chopper .

This is an official collaboration between Seiko and the One Piece franchise, celebrating both the anime’s enduring popularity and Japan’s railway heritage.

Seiko One Piece Shinkansen Watch Design

Rather than simply printing character images on the dial, Seiko has integrated numerous subtle details from both the anime and the train itself .

Dial and Shinkansen Inspirations:

• Blue Gradient Dial: The dial’s blue gradient mirrors the exterior artwork of the Setouchi Blue train
• Wave Pattern: A wave pattern from the side of the Shinkansen appears across the two upper sub-dials
• Luminous Hands: The hour and minute hands are coated with Seiko’s LumiBrite luminous material. Four glowing details beneath the Seiko logo are designed to mimic the headlights of a Shinkansen

One Piece References:

• Straw Hat: A tiny version of Monkey D. Luffy’s straw hat is visible on the index at the 1 o’clock position
• Jolly Roger: The Straw Hat Pirates’ flag is prominently displayed inside the small-seconds sub-dial
• Chronograph Seconds Hand: The chronograph seconds hand is shaped to reference Luffy and an anchor
• Anniversary Marker: A gold-coloured marker at the 50-minute position nods to the Sanyo Shinkansen’s 50th anniversary

Case and Caseback:

• Material: Stainless steel
• Size: Approximately 47 × 39.8 × 12.8 mm
• Caseback: Engraved with the One Piece Shinkansen logo and an individual edition number (out of 5,000)

• Water resistance: 10 bar

Why Is It Called the Shinkansen Edition?

The “Shinkansen” name refers to Japan’s famous bullet train network. The watch is specifically inspired by the Sanyo Shinkansen line, which runs between Shin-Osaka and Hakata .

The Shinkansen itself is the world’s first high-speed railway system, earning its “bullet train” nickname from its sleek, aerodynamic, bullet-like shape and speed . The Sanyo Shinkansen celebrated its 50th anniversary in 2025, which prompted the One Piece × Sanyo Shinkansen collaboration featuring three specially decorated trains .

The “Setouchi Blue” train—which inspired this watch—has been running between Shin-Osaka and Hakata since April 2025 . The watch’s blue gradient dial directly echoes this train’s exterior artwork .

One Piece Connection

The watch incorporates numerous references to Eiichiro Oda’s beloved One Piece series .

Confirmed references:

• Straw Hat Pirates Flag (Jolly Roger): Featured inside the small-seconds sub-dial
• Monkey D. Luffy’s Straw Hat: Visible on the index at 1 o’clock
• Chronograph Seconds Hand: Shaped to reference Luffy and an anchor

These elements are integrated into the watch’s design rather than simply printed onto the dial, creating a sophisticated and collectible timepiece .
