Seiko’s Innovations: Pioneering the Automatic Chronograph

When Seiko released the Caliber 6139 in 1969, the horological world took notice. This wasn’t just any new movement—it was the world’s first automatic chronograph with a vertical clutch and column wheel, setting a new benchmark for precision and reliability.

This innovation launched Seiko into the spotlight as a serious player in the high-end watch market, and paved the way for decades of groundbreaking advancements. From the development of Spring Drive and Kinetic technology to their elite Grand Seiko division, Seiko has consistently delivered precision, craftsmanship, and affordability.

The 6139’s legacy continues today in Seiko’s popular Prospex and Presage lines, where heritage meets modern watchmaking.
