New features added to the watch like the case and bracelet to create a classic and refined structure to this classic .
History of the SPEEDTIMER
This collection of watches was inspired by the 1960's Chronograph Watch that led Seiko to be endorsed by the international sports federation as the time piece for world sporting 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.
