Seiko Prospex Speedtimer Solar Chronograph

The 1969 introduction of the Seiko Speedtimer was an important milestone in the history of the chronograph. It was one of the world’s first automatic chronographs and featured Caliber 6139, whose precision in elapsed time measurement signified a real advance in the history of the automatic wristwatch.

Today, the newest generation of Speedtimer chronographs welcomes a series of three new creations whose design embodies the spirit of the original series but offer the added convenience, reliability and accuracy of Seiko’s solar technology.

All three watches will be available in November 2022 at select retail partners worldwide.
