help Grand Seiko Spring Drive FAQ
How accurate is the Grand Seiko Spring Drive movement?
Grand Seiko Spring Drive movements are rated to an accuracy of approximately ±1 second per day, or about ±15 seconds per month. This precision is achieved by combining a mechanical mainspring power source with electronic quartz regulation through a component called the tri-synchro regulator.
What makes the Spring Drive seconds hand different from other watches?
The Spring Drive features a continuously gliding seconds hand that sweeps without any ticking motion, unlike traditional mechanical watches that beat in discrete increments. This smooth glide is a direct visual result of the electromagnetic braking system that regulates the movement's speed.
Who invented the Spring Drive movement and how long did it take to develop?
The Spring Drive was invented by Japanese engineer Yoshikazu Akahane, who began working on the concept at Seiko in the late 1970s. It took over 20 years of development before the first Spring Drive prototype was unveiled in 1998, with Grand Seiko production models following in the early 2000s.
Where are Grand Seiko Spring Drive watches manufactured?
Grand Seiko Spring Drive movements are assembled at the Shinshu Watch Studio in Nagano Prefecture, Japan. The studio is situated in a mountainous region known for its clean air and natural beauty, which Grand Seiko frequently cites as an inspiration for its dial designs and finishing standards.
