Spirit of Innovation

The three design principles that define the
Evolution 9 Style

Evolution in aesthetics

Its aim is designs that clearly express the rich beauty of the balance between light and shadow, and the soft and subtle gradations between them.

Evolution in legibility

The hands are bold and multi-faceted and the indexes are powerfully three-dimensional. The result is enhanced legibility.

Evolution in wearing comfort

The lower center of gravity of the case and the wider lug provide a comfortable and stable fit.

9S Mechanical

The concept of Grand Seiko was born from the desire to build the world's best watch, and the collection continues to push precision in mechanical watches to the limits of timekeeping technology. As a true manufacture, Grand Seiko combines the latest technology with hand craftsmanship to raise the art of mechanical watchmaking to the highest possible level.

9R Spring Drive

Spring Drive, one of the great innovations in modern watch making history, regulates a spring-driven movement with state-of-the-art electronic technology that functions without batteries or other external power source. Its sole power source is a mainspring, which drives a series of gears. A rotor, connected to the end of these gears, generates a small electrical charge that activates an electronic circuit and quartz oscillator. Its accuracy is unprecedented for a watch wound by a mainspring. The development of the 9R Spring Drive movement was possible only because Grand Seiko is one of the few manufacturers with expertise in both mechanical and electronic watches.
