Made for runners and hikers who hit the mountains hard, the CORE APEX 2 GPS Outdoor Watch has dialed in what we need without the feature glut that weighs down other smart watches. This watch is durable with a Sapphire glass face, titanium bezel, and water resistant construction, and it connects with all five major satellite systems for reliable navigation and route finding. Its face features an easy to use dial and touch scrolling to manage fitness, health, data tracking, and navigation features, and Bluetooth connectivity lets us sync with our phone and integrate with compatible third party apps. The 2nd generation APEX has been updated with a more durable exterior, redesigned GPS antenna, enhanced navigation, next generation heart sensor, and longer GPS battery life, so our watch can work as hard as we train, compete, and play.
