Before creating Spring Drive, the choice was absolute. You either choose a mechanical watch and enjoy its traditional features and autonomy, but can tolerate its relative imprecision, or the accuracy of the electronic watch you wear has increased tenfold, but it requires a battery.
https://www.chronowrist.ruIn 1999, Spring Drive solved this problem by combining the best of the two existing watch technologies into a watch driven by a mainspring, which provides an accuracy of one second per day. Back then, and now, Spring Drive has been one of the biggest advancements in the watch industry.
Today, for two decades, Grand Seiko has introduced a new generation of Spring Drive movement, which is slimmer, more precise and has a greater power reserve. The 9RA5 movement took Spring Drive technology to a new level and opened a new era in the history of Grand Seiko.
Lighter, more precise, and more powerful. The new Spring Drive movement marks the beginning of Grand Seiko.
