Grand Seiko Spring Drive Power Reserve - #SBGA001

Long time a watch collector’s item, the Grand Seiko has been revered as one of the finest watches that Japan produces. Until now, obtaining a Grand Seiko proved difficult for many watch collectors, the watch was only available in Japan, necessitating a trip to Japan to purchase one, or turning to the used watch market to secure one themselves.

For the first time ever, SEIKO is making the Grand Seiko line of watches widely available outside of Japan. Mr. Hattori, SEIKO’s President and CEO announced that Grand Seiko would be available around the world for the first time in SEIKO’s history, and at the perfect time as well. 2010 was the 50th anniversary of the Grand Seiko line of watches, so it was fitting that it should be released worldwide to commemorate such an impressive achievement.

The Grand Seiko line of watches is among the very best in the entire world, rivaling the best watches built by both European and American companies. A rich SEIKO heritage of quality, accuracy, and aesthetics are used as a guide to incorporate some of the finest materials available to create these truly grand, Grand Seiko watches.

Every part and component used in the Grand Seiko is made in house by the skilled SEIKO craftsmen, with the strictest of standards. A solid stainless steel bracelet is combined with an impressive see-through back that highlights the craftsmanship of SEIKO that is put into every Grand Seiko Spring Drive Power Reserve. Simply put, the Grand Seiko is the finest that SEIKO offers.
