About Seiko Spring Drive
In 1977, Yoshikazu Akahane, a young Seiko engineer set out to build a watch wound by a mainspring that delivered split second accuracy. After 28 years and over 600 prototypes, he eventually achieved his goal, a marvelous technology known as the Seiko Spring Drive. Ninety-nine percent of the watches in the world represent the passage of time with the steady ticking motion of the second hand. The Seiko Spring Drive breaks from this mold by creating a steady movement of the second hand, resulting in a durable, stable, and more efficient system. Following the Spring Drive's 2005 series, Seiko has incorporated the technology in several of its watches. Sellers on eBay offer great deals on Seiko automatic models such as the Grand Seiko or the Seiko King. The Seiko Spring Drive also powers several Seiko Diver watch models, like the Seiko Marine Master, which comes with a luminous dial and is water resistant to depths of up to 1,980 feet. Silent and precise, the Seiko Spring Drive is an incredibly flawless watch system that represents the true passage of time.
