Three solar-powered chronographs with a shared heritage in design.



The 1969 introduction of the Seiko Speedtimer was an important milestone in the history of the chronograph. It was one of the world’s first automatic chronographs and featured Caliber 6139, whose precision in elapsed time measurement signified a real advance in the history of the automatic wristwatch.




Today, the newest generation of Speedtimer chronographs welcomes a series of three new creations whose design embodies the spirit of the original series but offer the added convenience, reliability and accuracy of Seiko’s solar technology.




All three watches will be available in November 2022 at select retail partners worldwide.





The sunray finish lends the dials a rich color and a modern feel.


As is the case with all Speedtimer chronographs, every detail of this design reflects the precision required for elapsed time measurement at the highest level. The chronograph second hand extends to align with the tachymeter markings at the dial edge. The chronograph minute hand at six o’clock and the center second hand are both in red so that the elapsed time stands out clearly against the dial and can be read at a glance. The date window is placed between the indexes so that the exact time can always be seen with ease.




All three watches are powered by Seiko’s solar Caliber V192 which features a 60-minute chronograph, a 24-hour subdial and, a six-month power reserve once fully charged.



The hour and minute hands and all twelve indexes are coated with Lumibrite so that the time of day can be read even in low light conditions.





The aluminum bezels are all in two tones, with tachymeter indications.





The seconds markers are located on the inner bezel ring so that the indexes can be large and highly visible.





The combination of hairline and smooth finishes on the bracelet and the curved sapphire glass gives the watches a classic yet sporty feel. The bracelet's thickness and weight provide stability and a high level of comfort on the wrist. The dials have a sunray finish which ensures exceptional legibility that is a core characteristic of every Prospex watch.




These three solar chronographs offer the superior specifications of the Prospex Speedtimer to all who want the precision of electronic timekeeping and the reliability and convenience of a watch that is powered exclusively by light.
