Grand Seiko Spring Drive Movement

Discover the revolutionary Spring Drive movement that combines the best of mechanical and quartz technology, achieving unprecedented accuracy with a perfectly smooth gliding seconds hand.

The Birth of Spring Drive

In 1999, Seiko introduced Spring Drive, a groundbreaking technology that took 28 years to develop. This innovative movement combines the soul of a mechanical watch with the precision of quartz, creating something entirely unique in horology.

How It Works

Spring Drive uses a mainspring as its power source, just like a traditional mechanical watch. However, instead of an escapement, it employs a Tri-synchro regulator that uses electromagnetic and mechanical energy to achieve remarkable accuracy of ±1 second per day.

The Glide Motion

The most visually striking feature of Spring Drive is its perfectly smooth seconds hand movement. Unlike the ticking motion of traditional watches, the Spring Drive seconds hand glides continuously, creating a mesmerizing visual effect that watch enthusiasts cherish.

Grand Seiko's Mastery

Grand Seiko has elevated Spring Drive to new heights with their exceptional finishing and attention to detail. Each Spring Drive watch represents the pinnacle of Japanese watchmaking craftsmanship.
