To honor the return of the World Athletics Championships to Tokyo, Seiko introduces a Prospex Speedtimer Solar Chronograph in a distinctive Edo purple dial, available in a limited run of 6,000 pieces.
At Seiko, timing has always been more than a function—it’s a legacy. For 19 consecutive editions, we’ve had the honor of serving as the official timekeeper of the World Athletics Championships, ensuring every performance is measured with absolute precision. In 2025, the championships return to Tokyo for the first time in 34 years, and so does our story.
To mark this historic homecoming, we are proud to introduce the Prospex Speedtimer Solar Chronograph World Athletics Championships Tokyo 25 Limited Edition (SSC955). This commemorative timepiece celebrates both Tokyo’s cultural heritage and the pursuit of sporting excellence that defines the championships.
The highlight of this model is its dial, crafted in a striking shade of Edo purple. Once cherished in the historic city of Edo—modern-day Tokyo—this color has been chosen as the official color of the Tokyo 25 championships. With its sunray finish, the dial reflects light beautifully at every angle, a vibrant reminder of Tokyo’s enduring spirit.

True to the Speedtimer lineage, every detail is designed with legibility and performance in mind. The chronograph seconds hand extends cleanly to the dial’s edge, while the date window sits precisely between indexes, ensuring that time can always be read with clarity. Its design draws inspiration from Speedtimer chronographs of the 1960s and 70s, blending heritage with modern functionality.
Inside beats the reliable solar Caliber V192, offering a 60-minute chronograph, a 24-hour sub-dial, and a power reserve of up to six months on a full charge. On the wrist, its combination of brushed and polished bracelet links and curved sapphire glass delivers both comfort and presence. The case back is engraved with the official World Athletics Championships Tokyo 25 emblem, underscoring its commemorative status.
