Smartwatcher emergency watches use state-of-the-art positioning technologies such as GPS, WPS and LBS to obtain the most accurate position of the watch wearer. Smartwatcher’s geo-location system is a hybrid system that combines all 3 methods above - and it is the fastest and most accurate in the market. In rare cases, if all three signals are weak, the geolocation might be less accurate.

Notice that with the PEARL watch, the geolocation is the one of the smartphone you have paired it with.
