COROS VERTIX 2S
The ultimate GPS watch for mountain adventures. Where accuracy and battery life matter most.
COROS VERTIX 2S is the flagship model from COROS — the highest-end watch with the best available technology, only premium materials, and the longest battery life. The VERTIX is typically chosen by climbers, mountain guides, and ultra runners — in short, by people who demand ruggedness and, above all, extremely long battery life from their watch.
What’s New
Innovations in key areas. Pushing the limits.
COROS VERTIX 2S focuses even more on the needs of mountain athletes and brings several improvements. A completely redesigned GPS antenna architecture for even more accurate positioning in mountain environments. Combined with the Outdoor Climb activity, this is the most advanced implementation of GPS hardware and software for precision in the mountains. The latest generation optical heart rate sensor with 5 LEDs and 4 light detectors delivers accurate heart rate readings during activities, sleep tracking, fatigue monitoring, and recovery time suggestions. The package now also includes two straps — a durable silicone strap and a comfortable nylon one. A new activity mode, Bouldering, is also introduced with the VERTIX 2S.
