This caliber is found in vintage Seiko Lord Marvel watches (ref: 5740-8000).18,000 vph X 2 = 36,000 vph Before the introduction of high-beat movements, the majority of watches operated at a frequency of 18,000 A/h, or 18,000 vibrations of the balance wheel per hour. In an attempt to improve accuracy, watch companies sought to create movements that beat at a higher frequency. Several Swiss brands set out to develop movements with a doubled rate of 36,000 A/h, and Girard Perregaux succeeded in bringing the first high-beat caliber to market in 1966's.
