Hello, and thank you for viewing my listing! This is a vintage Grand Seiko 4522-8000 Hi-Beat 36000 wristwatch from 1972. It is in generally good condition for a watch over 50 years old. However, it is currently not running. When the mainspring is wound, it runs for a few seconds but then stops immediately. It may be fixable with a simple repair.
