The Seiko Prospex Speedtimer World Athletics Championships Tokyo 25 Limited Edition Solar Chronograph celebrates a historic partnership between Seiko and World Athletics. Since 1987, Seiko has been the trusted official timekeeper of the World Athletics Championships, delivering precision timing to the world’s greatest track and field competitions. In 2025, the championships return to Tokyo for the first time in 34 years, and Seiko honors this milestone in its home city with a limited edition timepiece of just 6,000 pieces.

This remarkable Speedtimer features a dial in a striking shade of “Edo purple,” a color cherished in the ancient city of Edo—now Tokyo—and selected as the official color of the World Athletics Championships Tokyo 25. The case back proudly displays the event emblem alongside its individual limited-edition number, reinforcing its exclusivity.

Powered by Seiko’s solar technology, the V192 caliber offers a chronograph measuring up to 60 minutes in 1/5-second increments, a power reserve indicator, date display, and a 24-hour sub-dial, all while maintaining a precision of ±15 seconds per month. Once fully charged, it operates for approximately six months without additional exposure to light.

Crafted from stainless steel with a 39mm case, curved sapphire crystal with anti-reflective coating, and LumiBrite on the hands and indices, the watch is designed for durability and clarity. Water resistant to 100 meters, it also features a tachymeter scale and a three-fold clasp with push-button release. This limited edition Prospex Speedtimer beautifully blends heritage, innovation, and the spirit of world-class athletics.
