While the AIRSTAR was a departure from the traditional tool dive watch that Aquastar has became famous for among divers and aquanauts like Jacques Mayol and Phillipe Cousteau, it still featured a depth rating of 200 meter, a screw down crown and many attributes essential for serious water resistance.

This model is limited to 300 pieces per year, it is numbered and engraved on the case back..
