Grand Seiko 9RA2

9RA2 description Caliber 9RA2 has an accuracy rate of ±10 seconds per month and utilizes the Offset Magic Lever to reduce the movement’s thickness by 0.8mm. By moving the position of the crown further back, the watch’s center of gravity is lowered and a perfect fit on the wrist results. The Dual-size Barrels are of differing sizes and arranged to allow for expanded capacity while conserving space. This achieves a 120 hour power reserve. The One-piece Center Bridge guarantees the movement’s strength, durability and shock resistance. Together, these innovative technologies define the next-generation Spring Drive movement, Caliber 9RA2.
