One of the newer additions to the Seiko movement family, Caliber 6L35 combines a bi-directional automatic winding system with a very thin profile (only around 3.7mm in thickness). Employing 26 jewels, the 6L35 movement boasts a higher accuracy than other automatic movements and beats at a frequency of 28,800 vph and has a power reserve of 45 hours. This high-quality caliber has become a mainstay in the King Seiko collection.
