Rugged nautical digital wrist watch with three sensors: digital compass, barometer, and thermometer. Also displayed are moon phase, moon age, and tide data. Two timing modes: stopwatch and countdown/yacht race. New dual-level LCD screen displays more information and provides easy viewing. Convenient one-touch operation for major functions via large pushbuttons. Steel band.

Casio PATHFINDER watches contain small sensors that detect direction, pressure, and other conditions to help keep the wearer in touch with the natural world when challenging the great outdoors. The features and functions of Casio's sea-pathfinder watches are optimized for use on and near water--especially oceans, where both weather data and moon-and-tide data are critical. The SEA-PATHFINDER’S ability to provide up-to-the-minute information whenever it is needed has made it an essential piece of gear for boating, sailing, yacht racing--virtually any activity on or near water.  Check out this model, the Casio SPF40T-7V SEA-PATHFINDER Triple Sensor nautical watch.

Check out the Features and Functions list below. If you're like us, you'll be thoroughly impressed with this big, tough, nautical wristwatch. And if you like this watch but would prefer a resin band instead of steel, please have a look at the Casio SEA-PATHFINDER SPF40-1V and SPF40-2V on this same website. Although their cases have different color schemes and their bands are resin, functionally they are exactly the same watch.
