1991
World Athletics Tokyo

We introduced slit video and ultrasonic anemometers at this championship.
Seiko was proud to time the new world record of 9.86 seconds in the 100m event.

1993
World Athletics Stuttgart

A foul detection device was introduced for the first time in World Athletics.
The women’s 100m final had a heart-pounding finish, with the difference between first and second place being only 1/1000th of a second, something that might not have been discernible without Seiko’s state-of-the-art technology.

1995
World Athletics Gothenburg

The world record for the men’s triple jump was broken twice, and in the final of the women’s 400m hurdles, both the first and second place runners set world records, once again with a photo-finish separation of just 0.01 seconds.

1997
World Athletics Athens

Seiko introduced color slit video, contributing to even higher accuracy in measurements and more definitive judges’ decisions.

1999
World Athletics Seville

We captured the world record of 43.18 seconds in the 400m event at the 7th World Athletics Championships in Seville.

2001
World Athletics Edmonton

This was the first such event held in the Americas. In the men’s marathon, the difference between first and second place was only 1 second, and in the women’s 10,000m, the difference was a mere 0.04 seconds. Only a decade or so earlier, it would not have been possible to accurately measure and record such split-second times, and thus impossible to decide the winner. For many years now, Seiko’s technology has allowed judges to make definitive decisions backed by reliable data, so that both the athletes and spectators can accept the results, no matter how happy or painful.

2003
World Athletics Paris

We introduced our new anemometer (for measuring wind speed). If a following wind exceeds 2.0 m/s, any win is considered to be tailwind-assisted, and is not recognized as an official record.
This Championship was also a moment of pride for Japan, as a Japanese athlete won a medal in the men’s 200m sprint event for the first time.

2005
World Athletics Helsinki

In the women’s javelin throw, a world record of 71.70 meters was set on the first throw.

2007
World Athletics Osaka

We introduced a new race-walking judging system and penalty display board. An Ecuadorian athlete won the 20km walking race for the third time.

2009
World Athletics Berlin

This Championship was marked by “superhuman” performances in the men’s 100m and 200m events. First, an athlete set new record of 9.58 seconds in the 100m. Then, in the 200m event, a new world record of 19.19 seconds was set, achieving what was thought almost impossible.

2011
World Athletics Daegu

Beginning with the Daegu Championship, a one-false-start disqualification rule was adopted by World Athletics. The reigning hammer throw champion was disqualified for a false start, which shocked the sporting world. As a result, a Japanese athlete won the gold medal for the first time.

2013
World Athletics Moscow

We introduced highly visible full-color LED field event boards, LED anemometers, and LED lap counters, supporting many close records with state-of-the-art equipment.

A take-off evaluation system was introduced to make judgments in jumping events more accurate. Additionally, Seiko held the “Time to Shine” program to support the next generation of athletes, allowing young people to meet and engage with top athletes.
