The SATISFY COROS APEX 4 is a performance GPS watch co-designed by COROS and SATISFY for demanding days in the mountains. It features a 1.3-inch always-on display protected by scratch-resistant sapphire glass, delivering up to 65 hours of GPS tracking on a single charge. The collaboration brings SATISFY's trail-running aesthetic to COROS's proven navigation and endurance technology, resulting in a watch built for athletes who push into remote, high-altitude terrain.
