SPRING DRIVE

1977. A young Seiko engineer started to wonder how he could make his dream of "the ever-lasting watch" come true. In his vision: a watch wound by a mainspring and with one-second-a-day accuracy, a precision that only the finest electronic watches could deliver. This engineer, Yoshikazu Akahane, was a persistent and dedicated man. It took him 28 years, countless set-backs and over 600 prototypes, but he and his team eventually succeeded by inventing new technologies in every aspect of the watchmaker's art. In 2005, Seiko Spring Drive came of age.

GPS SOLAR

For centuries, the goal of watchmaker has been to offer ever higher standards of precision and convenience, but only rarely does a real advance in these areas take place. Thanks to Seiko’s relentless drive for innovation, new possibilities in watch technology continue to open up as the new Seiko Astron, the world’s first GPS solar watch, so dramatically demonstrates. With Seiko’s GPS Solar watch, new standards of precision, ease of use and global convenience have been set. Seiko’s GPS Solar watch is the most significant advance in watchmaking in a generation.

MECHANICAL

Seiko automatic movement 6R20. This high grade caliber is designed to place the Seiko firmly in the high quality mechanical market. The 6R20 movement is made of parts, all of which except rubies, are produced and assembled by Seiko Instruments Inc. The movement is exquisitely finished with an engraved rotor, polished edges to the bridges and hairline shading on the main surfaces. The high beat (28,800) movement delivers accuracy of -15~+25 seconds a day and the Spron 510* mainspring generates a power reserve of more than 45 hours. * Spron 510 is a high-elastic material developed by Seiko Instruments Inc., and its registered trademark.
