All watches are powered by the caliber 8R series, the brand’s most advanced automatic chronograph movement for mechanical watches. This caliber incorporates both vertical clutch and column wheel mechanisms which ensure the precision and durability. 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.
This caliber is designed and hand assembled completely in-house by Seiko's most skilled watchmakers.
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 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.
The construction of the chronograph pushers ensure the high level of operability crucial to a Prospex sports watch.
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.
The new Speedtimer chronograph takes inspiration from the 1969 Speedtimer, an important landmark in the history of chronograph watchmaking. Applying the technology invented for Seiko's stopwatches, the 1969 Speedtimer was the world's first automatic chronograph with a column wheel and vertical clutch. These two devices made the measurement of elapsed time more precise and error-free than ever before. The new model is to be the signature of the Speedtimer series. It inherits the innovative technology of the original model while achieving further evolution as a time measuring instrument.
The blue and red colors inspired by the 1969 Speedtimer are applied so that elapsed time can be read accurately at a glance. The dial has vertical hairline finishing and as the angle of vision changes, the dial turns from navy to vivid blue. Every detail of the watch reflects the high level of precision and performance of the watch as a time measuring instrument. The outer dial ring and sub-dial are in white so they stand out prominently against the blue dial to enhance legibility. The chronograph seconds hand is gently curved by hand for precise time measuring.
The bracelet can be replaced with a black leather strap whose stitching is designed to increase the strap's durability

The dial's color is inspired by Seiko's timing and measurement devices used in 1964, when the company was the official timekeeper of the greatest international sporting event held in Tokyo that year.
The watch is presented on a black crocodile strap with a matte finish. The stitching of the strap is designed to increase the durability.
The large concave pushers ensure the high operability for which the original stopwatch was renowned.
The latest Speedtimer chronograph takes inspiration from Seiko's first stopwatch designed for timing winter sports. As the official timing device at a major sporting event held in Sapporo in 1972, the original stopwatch’s features were tailored for winter conditions. These included a black dial for high legibility during competitions conducted on snow.
1/10th second stopwatch
The color scheme of the new Speedtimer is inspired by the original stopwatch of 1972.
The red indexes and chronograph sub-dial at 9 o‘clock enhance legibility against the matte, sandblasted black dial, which reduces the reflection of light from the sun and snow. The theme continues with the stainless steel case thanks to the use of black hard coating.
The watch is presented on a matte black calf leather strap with stitching designed to increase durability.
