We can't quite commandeer a nuclear submarine with the Garmin quatix 7X Solar Edition, but that's one of the few things it can't do on the water. With literally hundreds of features, this marine GPS smartwatch is specially designed for boating and nautical use—spanning everything from typical navigation, safety and tracking features, waypoint marking, and smart notifications of emails and texts to autopilot control of our boat when we're away from the helm, remote control of our onboard entertainment systems, streaming data (water depth, engine RPM, wind, etc.), and alarms that alert us to imminent tide changes or anchor dragging events. In other words, the watch not only lets us know where we are at all times, but it also lets us captain a boat, more or less. The Solar Edition also includes solar charging, adding days of battery life simply by wearing the watch on our arm as we're enjoying the sea or our inland fishing trip. That's just a start. The charts and maps span freshwater and saltwater, multi-continent topo maps, golf courses, and ski resorts. Built-in sports apps also include activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing, surfing, and indoor climbing—among other outdoor pursuits. Of course, we can also access performance and training metrics to monitor our health activity—and enjoy music apps, contactless payments with Garmin Pay, and smart notifications of emails and texts when paired with a compatible device. When our watch and phone are paired, we can manually message our live location to our contacts—or have the quatix send that automatically (in certain activities) with built-in incident detection. There's little this Garmin can't do—on the water and beyond.
