The Calibre 8R Series.

Designed for maximum precision
in every aspect.

All watches are powered by the calibre 8R series, the brand’s most advanced automatic chronograph movement for mechanical watches. This calibre 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 synchronisation.

This calibre is designed and hand assembled completely in-house by Seiko's most skilled watchmakers.

An authentic sports chronograph is now available
with a dial bearing the historic “SPEEDTIMER” name and a tachymeter bezel.

Bezel

This automatic chronograph features a tachymeter scale located on the outer bezel for enhanced legibility and a sporty aesthetic. This scale also combines the function to measure speeds from 50km/h to 60 km/h, paying homage to the original Speedtimer bezel format from 1969.
Case & Bracelet

The hammer-shaped push buttons used to operate the stopwatch function provide easy operability. The metal bracelet is well-balanced for a reassuring presence on the wrist. Combined with the stability of the case with its lowered center of gravity, it provides an excellent fit.
