Seiko Calibre 5D88A Kinetic Direct Drive Quartz Movement

Restore a compatible watch with the Seiko Calibre 5D88A Kinetic Direct Drive quartz movement, featuring hour, minute, central seconds, 24-hour, date, day, moon-phase, and direct-drive indicator functions.

The Kinetic Direct Drive system generates electrical energy through both wrist movement and manual rotation of the crown. This energy is stored in a rechargeable battery, while the indicator displays the available power reserve and real-time energy generation during manual winding.

Additional functions include an energy-depletion warning, overcharge prevention, electronic circuit reset, seconds-hand stopping, calendar correction, and moon-phase display.
