Seiko Prospex Solar Speedtimer SFJ001P1

The Speedtimer Prospex watch collection pays homage to Seiko's rich history of professional timekeeping, drawing inspiration from the brand's trailblazing innovations.

This particular design is propelled by a cutting-edge, in-house solar chronograph calibre featuring a stopwatch that can measure time down to the nearest 1/100th of a second.

Seiko's journey into precise sports timing instruments began with a significant milestone – becoming the official timekeeper for the 1964 Olympics in Tokyo. Despite lacking prior experience, Seiko's commitment to accuracy resulted in the creation of professional sports timing instruments, marking a turning point in the brand's legacy.

This commitment continues to thrive today, with Seiko holding the esteemed position of World Athletics Official Timekeeper since 1985. The brand diligently provides timing and measurement services to over 180 World Athletics events globally, showcasing an enduring dedication to precision and excellence.
