In the 1960s, Seiko announced itself on the international sports timing stage with a whole new generation of high-precision equipment that was enthusiastically endorsed by many international sports federations and used to capture elapsed time at many of the world’s leading sports events. Central to this success was a range of stopwatches that incorporated Seiko's innovative "heart-shaped cam" mechanism, a feature which delivered a level of precision once thought unachievable by manual sports timing devices. Then, in 1969, Seiko introduced the Seiko Speedtimer with the innovative Caliber 6139. It was the world's first automatic chronograph with a column wheel and vertical clutch, two devices that delivered real improvements in the measurement of elapsed time in a wristwatch and are still a prerequisite in high-functionality chronographs.

Four new solar chronographs inspired by the 1969 Speedtimer are now available. Powered by Caliber V192, they offer a 24-hour indicator, a time of day second hand, a 60-minute chronograph in a sub-dial
at six o'clock and a power reserve function.
They are offered in four different dial colours: white, navy, gold and black and will join the main Prospex collection.
The watch has sapphire crystal with anti-reflective coating on the inner surface. The bezel display material is zirconia ceramics to ensure both high legibility and rigidity.
The gold-colored second hand, reminiscent of the sunrise over a lush virgin forest, makes a strong presence on the dark green dial.
The charcoal-gray dialed Speedtimer is inspired from Seiko’s and Japan’s first chronograph wristwatch, the Crown Chronograph from 1964. The 1964 Crown Chronograph was designed from scratch and it marked the beginning of Seiko’s chronograph wristwatch manufacturing. It had a simple one-push mechanism but it amply demonstrated the same commitment to precision as would Caliber 6139 and all its successors with the inclusion of a column wheel to control the start, stop and reset functions.
The new Speedtimer incorporates a new movement from Seiko’s most advanced chronograph 8R series, Caliber 8R46.

The case shape is faithful to the original but its 39 mm diameter, the combination of hairline and smooth polishing on the bracelet and the curved sapphire glass bring it right up to date.
