Grand Seiko's Hi-Beat references use the 9S85 caliber operating at 36,000 vibrations per hour (5 Hz), one of the highest beat-rate movements in series production. The smoother-sweeping seconds hand and tighter rate stability are the Hi-Beat hallmarks. Available across multiple SBGH and SBGJ references in 36-44mm cases. The Hi-Beat program represents Grand Seiko's commitment to mechanical precision rivaling the best in the industry.
