Full-Color Preloaded Maps
Route Planning On-Watch
Create point-to-point routes directly from your wrist, using preloaded maps to choose smarter traverses and more efficient climbs. Adjust your route as conditions change without ever reaching for your phone or worrying about connectivity.
Points of Interest Search
Need water, shelter, or a way back to the trailhead? Use POI search to locate important points of interest around you, then follow on-watch navigation to get there with confidence.
Automatic Rerouting
If you stray from your planned route, automatic rerouting plans a new one for you based on your real-time location and destination.
Ski & Alpine Mapping
Navigate resorts and alpine zones with detailed ski and mountain maps, including lift lines, slopes, and terrain features. Ideal for lift-accessed days, ski touring, and mixed alpine missions.
Checkpoint Display & Alerts
Mark critical locations such as shelter, water sources, altitude milestones, and turnaround points, and view them clearly on your route with dedicated checkpoint displays. Set smart reminders for key checkpoints along your route and receive vibration and speaker alerts as you go.
Environmental Tools
Use the barometric altimeter and storm alerts to monitor sudden weather changes and get early warnings when conditions shift. High-altitude prompts remind you to check your blood-oxygen levels during steep climbs so you can stay aware of how your body is responding.
When the Trail Goes Dark, Stay Ready
Up to 30 Days of Battery Life
Pro-Grade Waterproofing
Endure Any Environment
Built for Every Expedition
With a full suite of adventure-ready modes and advanced training tools, the T-Rex Ultra 2 is built for the way you move outdoors.

From base camp intervals to summit-day efforts, your watch keeps pace with your goals.
Stay Connected Without Breaking Stride
