Cal. 6890 is an ultra-thin hand-winding two-handed movement produced by Seiko for Credor since 2009. Although derived from the 1969 Cal. 68A, Cal. 6890 and other recent movements in the Cal. 68 family (Cal. 6898, 6899, and 6830) are quite different in design and execution. Notably, the balance wheel is moved opposite the winding crown thanks to the round rather than squared-off shape of the movement, and the bridges are redesigned for more graceful appearance.
