A limited edition celebrating Seiko’s long legacy in athletics
Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Celebrating Seiko’s first precision chronographs, developed for international sporting competitions in 1964, as well as its 1969 introduction of the world’s first automatic chronograph, this Speedtimer Chronograph provides measurement of up to 30 minutes of elapsed time in 1/8-second increments.
The contrasting black subdials, LumiBrite hands and markers, and yellow chronograph hand provide enhanced legibility. Visible through the screwdown, see-through caseback, the 34-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The proprietary 8R46 movement includes a column wheel and vertical clutch mechanism allowing for smooth, stutter-free movement of the chronograph hand while providing longer wear and efficiency, and improving maintenance of the power reserve during chronograph operation.
