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.
