COROS APEX 4 46mm GPS Watch Black

COROS APEX 4 46mm is the premium GPS watch designed for athletes who tackle mountaineering, trail running, and vertical challenges. Its engineered construction combines a titanium bezel with a scratch-resistant sapphire crystal display, ensuring extreme resistance to shock and weather. The third-generation Memory-in-Pixel display is an “always-on” display, optimized for superior contrast and absolute readability even in direct sunlight or snow.

APEX 4 introduces an advanced vertical GPS algorithm combined with dual frequency, which eliminates the margin of error in calculating altitude and position among rock faces or dense forests. The new mapping engine is 30 times faster at rendering topographic maps, while the integrated microphone and speaker allow for hands-free calling and recording voice notes directly in the field. All this is supported by exceptional battery life, designed to cover multi-day expeditions without a single charge.
