In a powerful tribute to athletic performance and Japanese legacy, Seiko introduces the Prospex Speedtimer Solar Chronograph Limited Edition (SSC955) to mark the World Athletics Championships Tokyo 2025. With Tokyo hosting the prestigious event for the first time in over three decades, Seiko’s latest offering goes beyond watchmaking—it’s a celebration of time, history, and the pursuit of greatness.

The Legacy Of Seiko In Sports Timing

Seiko’s relationship with sports timing spans over half a century, dating back to innovations in the 1960s that changed the way the world measured time. From introducing Japan’s first chronograph in 1964 to the launch of the original Speedtimer in 1969, the brand has long held a place at the intersection of precision engineering and elite athleticism.

Since 1987, Seiko has served as the official timekeeper for World Athletics, deploying cutting-edge timing systems across global championships. As the event returns to Tokyo in 2025, the brand steps into its hometown spotlight with this commemorative Speedtimer, echoing both a sporting milestone and Seiko’s enduring role in capturing split-second excellence.

Edo Purple: A Colour of Culture and Championship

At first glance, what truly sets the limited-edition Speedtimer apart is its vibrant purple dial, inspired by “Edo purple”—a hue with deep historical resonance. Edo was the name for Tokyo during Japan’s feudal era, and this noble color, once favored by the ruling class, lends the watch a regal air and a rooted cultural identity.

Fittingly, this rich shade has been chosen as the official color of the World Athletics Championships Tokyo 25, making the watch’s dial not just aesthetically striking, but symbolically significant. It is a bridge between past and present, East and West, tradition and modernity.

Design Excellence: Legibility Meets Heritage

While the color draws attention, it’s the watch’s function-focused design that defines its professional caliber. Drawing on Seiko’s Speedtimer chronographs from the 1960s and ’70s, the dial layout is clean and supremely legible. A crisp white seconds hand stretches to the outermost edge of the dial, allowing for precise timing down to the last moment.

In a thoughtful touch of symmetry, the date window is positioned between indexes, ensuring that time-telling remains intuitive and unobstructed. Meanwhile, the subtle blend of hairline and mirror polishing on the case and bracelet creates a contrast that’s both sporty and refined.

Solar Power: Engineered For Endurance

Underneath the dial beats the solar-powered Seiko Caliber V192, which provides exceptional utility for those on the move. The watch offers a 60-minute chronograph, a 24-hour sub-dial, and a power reserve indicator—all powered by light alone. Once fully charged, the watch runs for up to six months, even in complete darkness.

The stainless-steel bracelet, combined with a curved sapphire crystal with anti-reflective coating, offers both comfort and durability, ready to accompany any lifestyle—whether trackside or city-bound.

A Collector’s Edition: Limited to 6,000 Pieces Worldwide

True to the spirit of exclusivity, the Seiko SSC955 will be released as a limited edition of 6,000 pieces globally. Each timepiece features a specially engraved case back with the World Athletics Championships Tokyo 25 emblem and its unique serial number, making it a treasured keepsake for sports fans and horology enthusiasts alike.

Priced at €770 in Europe, the chronograph offers remarkable value given its technical sophistication, commemorative value, and distinctive aesthetics. It will be available from August 2025 through Seiko Boutiques and select authorized retailers worldwide.

Final Lap: A Timepiece That Captures The Spirit Of Tokyo 2025
