Seiko
Seiko's upgraded automatic caliber offering a substantial 70-hour power reserve, nearly double the 4R35 it replaces in higher-end Presage and Prospex models. The extended reserve is achieved through a longer mainspring while maintaining the same 21,600 vph beat rate. Accuracy is tightened to -15/+25 seconds per day compared to the 4R35's wider tolerance. Represents Seiko's push to compete with Swiss movements offering 80-hour reserves.
