The word GPS stands for global positioning system and is used by military and civilians alike to spot their exact location. Although GPS is prevalent in aircrafts and automobiles, their reference in watches is rather limited. GPS Tracking Watches, at present are manufactured by Timex/Garmin and Suunto. A third company, the well known watch manufacturer called Casio, discontinued the production of these watches for reasons unknown.

Talking of technicalities, GPS Tracking Watches take the help of twenty seven satellites and a wide network of computers to calculate the latitude and longitude which allow the end user to determine a specific location at the tap of a button. Even in the worst of weather conditions, the GPS Tracking Watches calculate the user’s location to within a few meters from his destination. For this, the watches make use of a barometer, a compass, an altimeter and an array of advanced memory functions.

The function of a barometer is to measure the air pressure and warn the end user on an upcoming storm. The compass here is digital with the standard north south arrows and is extremely useful while hiking through unfamiliar country.  The altimeter in a GPS Wrist Watch allows the user to determine his current elevation and can also keeps track of his cumulative ascent and descent.   In order to get the correct measurement of the altitude, the altimeter comes equipped with a special feature called ‘temperature compensation’ which stops all interferences like air pressure and temperature variations from disrupting the data.

In a nutshell most GPS Tracking Watches come equipped with a north south arrow, bearing in degrees, bearing tracking, declination adjustment, rotating bezel and a resolution of one degree. There are some special watches which also have a built in heart rate monitor. Used mainly by athletes, the heart rate monitor determines the effectiveness of your training regime by keeping a track of the relationship between your heart rate and your exercise.
