Altimeter watches are easy enough to define. Simply put, they are wristwatches with a built-in altitude meter or altimeter. Although not 100 percent on point, altimeter watches are accurate enough, making them indispensable tools for hiking, mountaineering, skiing, skydiving, and other outdoor activities.

Aside the altitude meter, altimeter watches often include several other functions that outdoor enthusiasts especially skydivers will find useful and even life – saving, such as a thermometer, a barometer, a moon phase indicator, and a compass, among others. A watch with a built – in altimeter, barometer, and compass is often called an ABC watch, with the acronym obviously referring to the initials of the three functions.

Originally, altimeters worked by sensing pressure changes in the atmosphere. It is not an infallible system, but it is generally pretty accurate. This is because the higher one climbs — be that on a mountain hike, in an aircraft for skydiving, or otherwise — the less pressure there is in the atmosphere.

This is mainly because the Earth’s gravity pulls everything toward the planet’s centre, even air molecules. So, the closer you get to the centre of the planet, the higher the pressure. Readings can also be altered by weather as the atmosphere is under constant change, but the general functionality remains reliable enough that the technology is still widely used today.

In the United States, the most common non-barometric altimeter that still exists and is commonly used is GPS – based. As you may already know, GPS uses a network of satellites orbiting the Earth to help triangulate a given device’s exact location on the planet. While this is typically used to determine longitude and latitude on a map, it can also be enlisted to determine altitude.

Irrespective of which type of altimeter watch you end up choosing, it is important to keep their pros and cons in mind, because knowing the limitations of your technology can potentially end up saving your life, should you find yourself in an emergency survival situation.
