Despite claims by the manufacturer, the Saragosa isn't fully sealed and will allow the ingress of saltwater. A Penn SSV is better sealed against salt water than a Saragosa but is much heavier. The SSV also has a stronger drag.
Any reel will last a long time if you look after it. My Penn SS is over 30years old, copped an absolute flogging on beached with big fish and still runs like a swiss watch.
