AGS(Automatic Generating System).

Seiko released AGS in 1988. AGS stands for Automatic Generating System, but it was renamed as Kinetic in 1997. Although it is the first self-winding electricity generating quartz wrist watch of the world, there have been problems in mechanics, and in the end there was a feeling of convergence by renaming. (The similar system watches from Swatch also released an inexpensive watch.) After that, they released a new watch of the system called Spring Drive in 1999.


AGSはセイコーが1988年に発売した。AGSとはAutomatic Generating Systemの略だが、1997年にキネティックに名称変更された。世界初の自動巻き発電クォーツ腕時計ではあるが、機構的に不具合が続出し、最終的には名称変更をすることで収束を図った感があった。(スウォッチの安価なもので同様なシステムの時計も発売された。)その後、1999年に新たにスプリングドライブをリリースした。
