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. This watch is water-resistant up to 100m, making it a perfect timepiece for individuals who live an active lifestyle. It is appropriate for extended periods of snorkelling, but not for deep-sea diving. 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.
