GPS watches continue their core role of tracking location but now add fitness sensors, on-device maps, cloud sync, and safety features like live tracking and SOS messaging on some models. Wrist optical heart-rate sensors are convenient but chest straps remain more accurate for intense workouts. Modern watches export or sync standard files (GPX/TCX/FIT) to apps and cloud services; battery life depends on usage and model. Choose a watch based on map needs, battery life, sensor accuracy, and emergency connectivity.
Why GPS watches still matter
GPS watches began as compact location trackers and they remain that at heart: they show where you are, record routes, and help others locate you in an emergency. Over the past decade these devices have merged location with fitness sensors, maps, and cloud services so a single wrist device can replace several older gadgets.
What modern GPS watches can do
- Record multi-GNSS tracks (GPS plus other satellite systems) and save routes locally or to cloud apps.
- Provide turn-by-turn guidance and on-device maps for hiking or running.
- Track heart rate, pace, lap time, distance, and estimated calories burned using built-in sensors.
- Connect to chest straps and external sensors via Bluetooth or ANT+ for higher accuracy.
- Sync automatically with phone and web services (for example, activity apps that accept GPX/TCX/FIT exports).
Navigation and safety features
Many watches support live-tracking so friends or family can follow your progress in real time. They also offer incident detection and the ability to call for help. Some models now include cellular connectivity or satellite emergency messaging for SOS when you have no phone signal - check specifics for each model before buying.
Sensors and accuracy
Wrist-based optical heart-rate sensors are convenient and work well for steady-state exercise. For high-intensity intervals or very precise heart-rate data, a chest strap remains more accurate. GPS accuracy has improved with multi-constellation GNSS, but urban canyons and dense tree cover can still cause errors.
Syncing, formats, and data storage
Instead of transferring XML files to a PC as was common years ago, modern watches sync automatically to cloud platforms and smartphone apps. Most services let you export or import standard files (GPX/TCX/FIT) and retain historical routes as long as you keep the associated account. Battery life varies by model and usage: expect anything from a day of heavy GPS use to multiple days or weeks in low-power smartwatch modes.
Choosing the right watch
Decide what matters most: map detail, battery life in GPS mode, sensor accuracy, or emergency connectivity. If safety off-grid is a priority, look for models with verified satellite or cellular SOS features and read the exact manufacturer specifications. 1
GPS watches have evolved from simple location tools to multi-sensor, connected devices that serve both fitness and safety needs. They won't replace a smartphone for everything, but they can consolidate several gadgets - GPS units, basic heart-rate monitors, and lap timers - into one convenient wrist device.
- Confirm which specific watch models currently include built-in satellite SOS or integrated satellite emergency messaging (and under what conditions).
- Verify current lineup of popular brands that offer satellite or cellular SOS in their watches and list accurate model references if needed.
