Grand Seiko’s pursuit of accuracy reaches new heights with the Spring Drive U.F.A., where “U.F.A.” stands for “Ultra Fine Accuracy.” This groundbreaking release features the new Caliber 9RB2, which sets a new standard in precision for mainspring-powered movements with an astonishing annual rate of just ±20 seconds—the most accurate wristwatch movement of its kind in the world as of April 2025. At just 37mm in diameter, these watches are the smallest models powered by the 9R series to date, designed for exceptional comfort on smaller wrists.
