What Does an Altimeter Do on a Watch?

Multifunction watches, as the name implies, serve a variety of purposes. They are chosen by the wearer to suit his or her unique demands. In addition to telling time, they can perform calculations, measure speed and set appointments. An altimeter watch is designed for people whose survival depends upon knowing their elevation above land or sea.
  1. Function of the Altimeter

    • An altimeter is a device that measures altitude above sea level or a relative fixed point by measuring atmospheric pressure and providing a readout in either feet or meters.

    Functions of the Altimeter Watch

    • In addition to displaying current altitude, altimeter watches can provide information such as temperature, direction and rate of climb or descent; track distances in elevation traveled; indicate speed; and estimate time of arrival.

    Varieties of Altimeter Watches

    • Altimeter watches are similar in appearance to digital-readout wristwatches and come in a wide variety of styles and prices, with additional functions such as compasses and global positioning systems, to suit individual tastes and budgets.

    Recreational, Commercial and Military Uses

    • Altimeter watches are especially useful for outdoor activities such as skydiving, mountain climbing, ballooning, hang-gliding, surfing, hiking, camping, snowboarding, biking, skiing, backpacking, hunting, aviation and search and rescue operations.

    Use in Food Preparation

    • Because cooking times vary with respect to elevation above sea level, particularly when baking and boiling, altimeter watches are also useful in food preparation.
