Grand Seiko Hi-Beat

The Grand Seiko Hi-Beat is a line of high-frequency automatic mechanical watches engineered and manufactured by Japanese watchmaker Grand Seiko. The series was created at Seiko's Suwa factory (Suwa Seikosha) in Nagano Prefecture and launched in 1967. These watches feature movements that beat at 36,000 vibrations per hour (10 beats per second) resulting in smoother seconds-hand sweep.
