Seiko has revealed a wristwatch unlike anything else in its catalog. Called the Seiko Star Time, this one-of-a-kind mechanical watch was built specifically for baseball star Shohei Ohtani and can display accumulated time across a span of roughly 114 years, or one million hours. The piece marks Ohtani’s tenth year as Seiko’s brand ambassador in Japan and was handed to him in person on July 3, 2026 by Seiko Chairman, CEO, and CCO Shinji Hattori.
Unlike a typical limited edition Seiko watch, the Star Time will never go into production. It is a single piece, made for a single wrist, and there is no price tag attached because it was never meant to be sold.
What Is the Seiko Star Time
The Seiko Star Time began three years ago after Ohtani reportedly asked Seiko’s development team a simple but weighty question about how much longer his baseball career could realistically continue. Seiko’s engineers took that question literally and set out to build a mechanical movement capable of counting far beyond what any standard watch complication allows.
The result counts hours, not just the time of day. Seiko says it is currently the only wristwatch in the world that can display accumulated time up to one million hours using a system of layered rotating discs.
How the Five Rotating Discs Work
The dial is built around five stacked rotating discs, each responsible for a different scale of accumulated time. A diamond marker is set into each disc to indicate when it completes a full rotation, and a single diamond sits at the center of the display, representing the North Star as a fixed point of reference.
| Disc | What It Tracks |
|---|---|
| Innermost disc | Current time in 24-hour format |
| Disc 2 | Up to 1,000 hours |
| Disc 3 | Up to 10,000 hours |
| Disc 4 | Up to 100,000 hours |
| Outermost disc | Up to 1,000,000 hours |
Because the discs move so slowly, their motion is nearly impossible to see with the naked eye, similar to watching stars shift across the night sky. This is where the Star Time name comes from.
Design and Case Details
Building five nested disc mechanisms into a wearable case required Seiko to develop a new movement architecture from scratch. Here is how the case and materials break down.
| Specification | Detail |
|---|---|
| Case material | High-Intensity Titanium |
| Case width | 41.8mm |
| Case thickness | 17.4mm |
| Crystal | Box-shaped sapphire with inner anti-reflective coating |
| Crown detail | Blue sapphire set into the crown top |
| Water resistance | 10 bar |
| Strap | Blue silicone, custom-cut to Ohtani’s wrist |
| Case sides | Etched with lines evoking the trajectory of stars |
| Production | One-off, not for sale |
The titanium case keeps weight manageable despite the added thickness needed for the disc stack, and the silicone strap was sized specifically for Ohtani rather than offered in standard lengths.
Why Seiko Built a Watch That Tracks One Million Hours
Seiko has worked with Ohtani as a brand ambassador in Japan for a decade now, and the Star Time was designed as a tribute to the steady, daily effort behind his career rather than as a product launch. The number itself, one million hours, works out to just over 114 years, framing the watch as a symbol of a goal far larger than any single season or contract.
The design language leans into that idea. The North Star diamond at the center never moves, while the surrounding discs turn at wildly different speeds around it, a visual echo of consistent effort building toward a distant, unmoving goal.
Is the Seiko Star Time Available for Purchase
No. The Seiko Star Time is not for sale and Seiko has confirmed there are no plans to put it into production. It exists as a single piece, presented directly to Ohtani, and will not appear in Seiko boutiques or on Seiko’s website as a purchasable model.
Readers looking to buy a Seiko watch in India right now will need to look at Seiko’s existing retail lineup instead, since this particular piece will not be one of them.
