Seiko Unveils Bespoke Star Time Watch for Shohei Ohtani's Decade-Long Partnership

In a remarkable gesture to honor baseball icon Shohei Ohtani's enduring partnership, renowned watchmaker Seiko has introduced a custom-designed mechanical watch. This extraordinary timepiece, named the 'Star Time,' was conceived over three years, drawing inspiration from Ohtani's contemplative query about the span of his illustrious career. The watch is a testament to Seiko's horological innovation and its deep appreciation for its Japanese brand ambassador.

Seiko Dedicates Unique 'Star Time' Watch to Baseball Superstar Shohei Ohtani

In July 2026, a significant event unfolded in the world of horology and sports. Seiko, the distinguished Japanese watch manufacturer, presented a singular mechanical watch to baseball phenomenon Shohei Ohtani. This exclusive creation, dubbed the 'Star Time,' was meticulously developed over approximately three years, prompted by Ohtani's reflective question regarding the duration of his professional baseball journey. Unlike traditional timekeeping devices that measure seconds or feature standard complications, the 'Star Time' is engineered to track cumulative time across five distinct scales, capable of recording up to an astonishing one million hours—equivalent to more than 114 years. This innovative display mechanism, utilizing a system of five rotating discs, represents an unprecedented achievement in wristwatch design, according to Seiko. Shinji Hattori, Seiko's Chairman, CEO, and CCO, personally bestowed this exceptional watch upon Ohtani, solidifying its status as a one-of-a-kind piece that will not be available for public sale or mass production.

The 'Star Time' is encased in a robust 41.8mm High-Intensity Titanium frame, featuring a substantial 17.4mm profile, including its markedly domed crystal. Instead of conventional hands, time is indicated by a striking blue multi-layered display comprising five concentric rotating discs. These discs chronologically monitor periods of 24 hours, 1,000 hours, 10,000 hours, 100,000 hours, and finally, up to one million hours. The innermost disc also serves the practical purpose of displaying the current time in a 24-hour format. During the collaborative development phase, Ohtani and Seiko's engineering team made the thoughtful decision to embed a single diamond into each rotating disc, imparting a distinctive and luxurious aesthetic to the display. To accommodate these unusually thick display discs, Seiko innovated a specialized movement architecture and re-engineered both the movement layout and the assembly process. A box-shaped sapphire crystal, enhanced with an anti-reflective coating on its inner surface, protects the intricate display. The watch is complemented by a custom-fitted blue silicone strap, tailored to Ohtani's wrist, and boasts a 10-bar water resistance rating, ensuring its suitability for daily wear despite its highly experimental and unique nature.

The creation of the 'Star Time' stands as a powerful symbol of the synergy between precision engineering and the pursuit of excellence in sports. It challenges conventional notions of timekeeping, transforming a practical instrument into a philosophical artifact that reflects on the preciousness of time and the legacy of a career. For Ohtani, this watch is more than just a gift; it is a wearable metaphor for his dedication and the remarkable journey he has undertaken in baseball. For Seiko, it reinforces their commitment to innovation and their ability to craft bespoke masterpieces that resonate with profound personal significance. The decision to keep it a one-off piece further elevates its mystique and value, making it a truly unparalleled tribute.
