Garmin fenix 8 Pro � 47 mm, AMOLED Sapphire, Titanium with Graphite/black silicone band. Built for athletes and adventurers whose pursuits can make it impractical to carry a phone, this multisport GPS smartwatch is a breakthrough. Leave your phone behind during an activity, and use the watch�s inReach technology1 for voice calls and LiveTrack location sharing when you have an LTE network connection. Or access two-way messaging and interactive SOS capabilities from either an LTE connection or off-grid satellite link. Built to endure, this premium design is dive-rated and features leakproof buttons, a metal sensor guard cover and bright 1.4'' AMOLED display with a scratch-resistant lens and titanium bezel, so it can go places your phone can�t. It�s tested to U.S. military standards for thermal, shock and water resistance. When you�re venturing into off-grid locations, including up to 50 miles offshore, the watch�s inReach technology allows you to send messages and get location check-ins, once you establish a satellite link, with no phone connection required. Use LTE network connectivity to make and take calls directly from your watch, without carrying your smartphone along. Plus, watch functions can be controlled with phone-free voice commands, or use your smartphone�s voice assistant to respond to text messages and more. Navigate your adventures by using preloaded TopoActive maps with relief shading, plus built-in maps for golf courses and ski resorts around the world. A dynamic round-trip routing feature offers suggested routes to bring you back to your starting point on time.
