COROS APEX 4 GPS Watch

The COROS APEX 4 GPS watch is built as a high‑performance mountain‑sports timepiece, designed for serious athletes venturing into long treks, rugged terrain, and demanding environments. With alpine‑grade materials, high‑precision navigation, and robust training analytics, it’s made to support trail running, climbing, ski touring, and multi‑sport adventures.

Key Features
Alpine‑Grade Engineering: The watch features a Grade 5 titanium bezel, reinforced lugs, and scratch‑resistant sapphire glass, combining durability with lightweight comfort.

Display Optimised for Outdoor Conditions: Equipped with a Memory‑in‑Pixel (MIP) touchscreen — 1.3″ for the 46mm size or 1.2″ for the 42mm variant — ensuring readability even in bright sunlight, snow, or shadows.

High‑Precision Navigation: Dual‑frequency GPS plus enhanced vertical‑GPS algorithms and a dual‑range barometer provide accurate tracking in forests, mountains, and technical terrain. Global topographic maps with turn‑by‑turn navigation are built in.

Strong Battery Life: The 46mm model offers up to 65 hours of full GPS mode, while the 42mm size provides up to 41 hours under the same mode. Regular watch-mode usage lasts significantly longer.
