    The replica Grand Seiko Spring Drive movement is uncommon in watchmaking. It takes a traditional mechanical movement and blends it with the finest quartz. The movement has an accuracy of +/- 15 seconds per month, or 1 second per day. COSC certified watches must meet at least +6/-4 seconds per day, non-COSC certified watches usually have an error of around +/-10 seconds per day. Spring Drive movements can be found in different model lines including the Elegance, Masterpiece, Sport and Heritage lines. <p>replica Grand Seiko</p>
