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.
