Garmin has announced a new multisport smartwatch for land and water activities, with solar charging that can extend battery life up to 24 days. The Garmin Quatix 6X Solar has similar specs to the existing Fenix 6X Pro Solar, including a bright 1.4-inch display designed to be readable in direct light, smart notifications, contactless payments via Garmin Pay, and storage that can Store up to 2000 songs so you can go out without your phone. The new device also has a set of features designed specifically for open water adventures, including the ability to transmit NMEA 2000 boat data so you can see information from your boat's sensors right on your wrist, including speed data, depth, temperature and wind. You can even pair the watch with an onboard autopilot and use it to change course, activate model steering, and follow a GPS route. Garmin says the battery can last 21 days in smartwatch mode (i.e. without GPS), which can be extended up to 24 days with a solar charge. A customizable power manager lets you see how adjustments with settings and sensors affect battery life, so you can find the right balance on the fly.
