In the 1960’s, 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.
Today, a new series of six watches inspired by the Speedtimer and Seiko’s rich and continuing tradition of sports timing join the Prospex collection. A limited edition watch with a new automatic chronograph movement pays faithful tribute to the design of the 1964 stopwatch, while a second version with the same caliber and a series of four solar chronographs complete the range.

SPEEDTIMER Mechanical Chronograph

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.

1964

Crown chronograph

Dial

The dial design is a subtle nod to the 1964 Crown Chronograph. Its beveled hour markers, sharp hour and minute hands with colored Lumibrite, its chronograph pushers and markers on the outer dial ring echo the design of the original.
The chronograph second hand is gently curved down towards the dial so that the tip of the hand is as close as possible to the dial’s markers and extends to the tachymeter markings at the very edge of the dial, thus ensuring that elapsed time can be read accurately at a glance.

Push buttons
& Crown

The construction of the chronograph pushers ensure the high level of operability crucial to a Prospex sports watch.

Bracelet

The watch is presented on a stainless steel bracelet that is specially designed and constructed for the series. Its thickness, weight and low center of gravity ensure stability and a high level of comfort on the wrist.

New Movement
Caliber 8R46

This watch is equipped with a new movement from Seiko’s most advanced chronograph 8R series, Caliber 8R46. It shares the same performance attributes as Caliber 8R48 but incorporates two sub-dials instead of three and has a date window at the six o’clock position. The vertical clutch and column wheel ensure the precision and durability which are the hallmarks of the 8R Caliber series. The escapement is lightweight and strong, thanks to the use of MEMS technology which enhances the stability of the watch’s precision. With the push of the reset button, the hands return back to zero instantly and in perfect synchronization.
