The Grand Seiko 9R65 is an automatic Spring Drive movement renowned for its exceptional accuracy and innovative hybrid technology. While the first Spring Drive watch was presented in 1999, it was not until after a further four years of intensive development that the first Grand Seiko 9R Spring Drive was created. To meet the high standards of Grand Seiko, the winding system and drive time were upgraded from a manual winding system with 48 hours of power reserve to automatic with a 72-hour power reserve. The automatic winding mechanism uses the Magic Lever mechanism developed in 1959, but with improved productivity, maintainability, and durability to enhance its winding efficiency.
