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. A chronograph watch is a watch with a stopwatch function built into the movement. The mechanism is used to measure elapsed time, where the precise length of time needs to be known. Seiko believes that the wristwatch is an ultimate accessory. The best watches live in harmony and interact with the wearer, and their functions offer a reassuring and emotionally satisfying bond.
