Seiko and World Athletics
Since 1987, Seiko has been the timekeeper of choice for World Athletics, the world championships of track and field. In 2025, the World Athletics Championships return to Tokyo for the first time in 34 years, and Seiko will once again deploy its state-of-the-art timing equipment in the city of its founding, marking a momentous event in its history in sports timing.
In commemoration of World Athletics 2025, Seiko marks the latest chapter in this legacy with a Prospex Speedtimer Solar Chronograph limited edition while honouring the performances of the approximately 2,000 athletes who will take part in the championships.
Dial
The dial of the limited edition Speedtimer has been created in a beautiful shade inspired by “Edo purple”, a colour that was cherished in the ancient city that would become modern-day Tokyo. As a nod to Tokyo’s historical name of Edo, the hue was chosen as the official colour of the World Athletics Championships Tokyo 25.
Case back
The back of the watch features the event emblem with the limited number of 6,000 pcs.
