This 1965 cal 5722 Grand Seiko Chronometer with box, papers etc. in nearly-new condition just sold for 498000JPY/4864USD/27000DKK, or about four times the going price for reasonable-condition heads without any paperwork, boxes etc.

With 133 bidders, it appears interest for early vintage Grand Seiko is increasing. The most comparable, modern Grand Seiko (SBGW033) appears to be retailing at around 6500USD making the 4864USD most reasonable for such a unique time capsule.
