Precision in every aspect. A new Speedtimer chronograph.

The creation of the 1969 Seiko Speedtimer was an important landmark in the history of the chronograph. It was one of the world’s first automatic chronographs but its true significance lay in that fact that its movement, Caliber 6139, was the first to incorporate both a column wheel and a vertical clutch, two devices which made the measurement of elapsed time more precise and error-free than ever before. Today, a new creation pays homage to the 1969 original and showcases many of the most innovative aspects of Seiko’s watchmaking.
