The new COROS APEX 4 – precision, durability, and speed in one watch

When your adventures take you beyond familiar trails, you need gear that keeps up with every step. The new COROS APEX 4 is tougher, faster, and more precise than ever. It combines premium materials, smarter navigation, and advanced performance features to help you stay on pace, no matter the conditions.

Refined design with a premium feel

The COROS APEX 4 is built with a titanium frame and sapphire glass, offering both durability and an elegant finish. Available in 46 mm and 42 mm sizes, both models feature a new Memory-in-Pixel (MIP) display that stays always-onand perfectly readable in any light — whether under bright sun, snow, or shade. It’s designed for clarity and endurance, just like the athletes who wear it.

Faster and more detailed navigation

One of the most notable upgrades — maps and graphics now load up to 30x faster than before. Routes, elevation profiles, and workout data appear instantly, making navigation smoother and more responsive. The dual-frequency GPS ensures even greater accuracy in mountainous terrain or dense forests, while enhanced topographic and street maps include trail names, and turn-by-turn directions.

A battery built for long-distance adventures

The COROS APEX 4 is made to go the distance. The larger 46 mm model delivers up to 65 hours in Endurance mode, 53 hours in High mode, and 41 hours in Dual-Frequency GPS mode for maximum tracking precision. The 42 mm version offers up to 41 hours in Endurance mode, 34 hours in High mode, and 26 hours in Dual-Frequency mode.

Smarter training insights

The APEX 4 brings enhanced training analytics — tracking recovery and performance with more accurate sensors. It automatically adjusts workout recommendations based on your recent activity and recovery time. With HRV analysis, altitude adaptation monitoring, and a new heat efficiency metric, you can better manage your training in any environment, from high heat to high altitude.

Everyday intelligence meets outdoor readiness

Built for endurance, yet designed for daily life, the APEX 4 offers music playback without a phone, smart notifications, sleep tracking, and breathing exercises. It also includes real-time environmental data such as air pressure, wind speed, temperature, and short-term weather trends — so you can plan safer hikes or mountain runs. The COROS app lets you customize button controls, data fields, and dive deep into detailed performance analytics.
