Seiko Prospex Solar Tokyo Limited Edition SSC955

Seiko celebrates the World Athletics Championships Tokyo 25 with a limited-edition Prospex Speedtimer Solar Chronograph. This year marks the 19th consecutive World Athletics Championships timed by Seiko.

Seiko’s journey in watchmaking has been marked by a series of pioneering advancements in sports timing. From its pioneering use of a heart-shaped cam for more accurate timing in stopwatches in the early 1960s to the creation of Japan’s first chronograph in 1964 and the original automatic Speedtimer in 1969, Seiko has consistently set and upheld a high standard for precision.
