    The earliest and largest watches considered more of the pocket watch types, were invented within Tudor, England in the sixteenth century. These timepieces weren't worn around the wrist then but mostly as a necklace around the neck due to their larger designs.

    These pocket watches became more commonplace within the earlier seventeenth century and were crafted to be more accurate in their time keeping as well.

    A man named Mr. John Harrison was a watchmaker by trade and had taught himself this craft completely with great and wonderful results. Mr. Harrison created a greater accuracy within watches of his times and found that the exact time could help in determining precise longitudinal locations of the ships for the Captains. He worked endlessly for over ten years to invent only four Chronometer Harrison Marine watches in the latter seventeenth century; these miraculous watches were also the size of smaller dinner plates. Through many tests by the Queen's Captains these watches proved their worthiness to her and Mr. Harrison then received $20,000 in pounds as a prize for his creative and helpful inventions by Queen Anne of England herself.

    The history of wrist watches began with a man named Patik Phillippe in the early nineteenth century. Wrist watches were worn at this time mostly by women as accessories; the men carried pocket styled watches as their timepieces. During this century, the watch company called Rolex was opened and owned by Mr. Hans Wilsdorf in the year 1905. Wrist watches gained an added quality by the addition of an alarm within them in the year 1914 and the watch company called Seiko was opened in the year 1924 within Tokyo.

    In the twentieth century, wrist watches were very popular, but some men still loved their tried and true pocket watches and these were still being manufactured in larger quantities up until the 2nd World War when production decreased dramatically. In the year 1952, wrist watches that were powered by batteries instead of winding mechanisms were out on the markets; this was a large and wonderful advancement within the timepiece era.

    Watches, which were electronic, were the most popular in the 70's and in the 90's a reemergence of mechanical watches happened due to vintage and nostalgic wants in the watch markets of that time. Over 25% of Swiss made watches are all mechanical and not electronic. They keep to the original quality that first endeared these timepieces to their clientele and faithful customers.

    More accurate than any previous system known to man, GPS (Global Positioning System) are used as navigational tools to determine specific location data. GPS tracking watches, use twenty-seven satellites and a broad network of computers to calculate the user's latitude and longitude to within a few meters.

    With wearing a GPS tracking watch, its simple to track your location, speed, direction and distance to your destination and many more functions. You can save and chart trips, retrace your steps back to your starting point, program routes in advance, and save the coordinates of interesting locations.

    Even in conditions of low visibility, you'll know how to reach your destination, and know right where you are. A lot of models also include a Barometer, Compass, Altimeter, and advanced memory functions.

    A barometer is an instrument that measures atmospheric pressure, or air pressure. With a barometer you can forecast upcoming weather, low-pressure weather systems tend to bring cloudy skies and precipitation, and high-pressure systems usually come with very few clouds or precipitation. When the barometric pressure drops, its time to be watching for more clouds and maybe bad weather. So, a GPS tracking watch that can read barometric pressure is a convenient and useful way of staying informed of upcoming weather conditions monitored right on your wrist.

    Of course a digital compass is an extremely useful function to have in a watch. Whether you're navigating through an unfamiliar city, hiking through the backcountry, or sailing on the ocean. There are slight differences in compass functionality from GPS tracking watch to GPS tracking watch, but most models feature:

    * Bearing in degrees

    * North-south arrow

    * Bearing tracking

    * Declination adjustment

    * Rotating bezel

    * Resolution of 1 degree

    An altimeter GPS tracking watches is a wrist top instrument that allows the wearer to determine their current elevation. Of course, that's not all - combined with memory, an altimeter watch can keep track of your total and cumulative vertical ascents and descents, as well as the number of runs (for skiing or snowboarding, for example). In some watches, the altimeter can be used to estimate your vertical speed, or sound an alarm when you reach a set altitude.

    The altimeters used in GPS tracking watches base their measurements on air pressure - in a nutshell, the lower your altitude is, the more air there is above you is, and the heavier it is. So when you move uphill, the air pressure sensor in the watch detects the decreasing air pressure, and automatically converts the pressure drop into a reading of your increasing altitude. Of course, it is not easy to get perfectly accurate measurements of altitude, because there many factors that can cause air pressure to fluctuate.

    This is why many altimeter watches feature "temperature compensation," and why the altimeter must to be calibrated regularly (by simply entering the current barometric pressure or setting to a known altitude).

    An altimeter is an important and useful piece of gear for many outdoor activities, including running, biking, and hiking, skiing, or snowboarding. Pilots of small planes often wear an altimeter watch as a back up in case of instrument failure - although be aware that an altimeter of this type cannot be used successfully in a pressurized plane.

    There are also various models that have built in heart rate monitors and other built in functions.

    Heart monitors are one of the few pieces of equipment more important in fitness training. Serious cyclists, runners, and other athletes know that you can only determine how effective your training regimen is by keeping track of the relationship between your workout and your heart rate. There is not a more convenient way to do this than a heart GPS tracking watch with a built in heart rate monitor. Some GPS tracking watches use a chest strap to monitor your heart rate, and send data wirelessly to the watch.

    One model allows you to program the GPS tracking watch with your upper and lower heart rate limits and alerts you if your heart rate goes outside the programmed ranges. It also monitors how your heart rate changes with altitude, and keeps tracks of your highest, lowest, and average heart rate while you're training. GPS tracking watches also allow you to upload your data to your PC where you can use the included software to analyze, compare, and save your own personal stats.
