Caliber 6890 is a manual-winding movement manufactured by Credor and introduced in 1972. As part of the Seiko 68xx family, it represents an in-house development from Seiko's high-end brand, distinguished by its ultra-thin construction—a notable achievement for mechanical movements of that period. Production has since been discontinued.
