Each Seiko Chronograph is a unique model of timepiece that serves as a stopwatch and a display timepiece. An independent sweep second hand is a standard feature of a chronograph, and it is typically started, stopped, and reset to zero by repeatedly pressing the button.

Seiko’s contribution to the development of the chronograph is well known thanks to the 1969 release of Caliber 6139, the world’s first automatic chronograph with a column wheel and vertical clutch. In fact, however, the history of Seiko’s chronographs started long before, with a pocket watch chronograph made in the early 1940’s. Today, this long and proud tradition in the measurement of elapsed time is celebrated in two new automatic chronographs that commemorate two landmark watches, from 1964 and 1969. One is in the Prospex collection and the other in Presage. Both will be available from December, 2019 at Seiko Boutiques and selected retailers worldwide.
