Right back to basics, an altimeter is a device which measures changes in height or as the pro’s say - altitude. The simplest way of measuring altitude is to measure the way the pressure of the air around us changes as we ascend or descend, the air gets thinner the higher we go up. Unfortunately this change is very slight (unless you have a jet !) and you need an extremely accurate instrument to measure the change in air pressure experienced by walkers, or even downhill ski racers. Until recently the only way to do this was with a very sensitive mechanical device, too big, delicate and expensive for the average Joe to carry around. Now the Suunto Core range of altimeters accurately measure altitude. Origionaly electronic gauges were made for aircraft - but these were incredibly expensive, very exotic. And then those electronics whizz kids went and miniaturised them, shrunk them until they fit into an ordinary watch !!! Now everyone can have one.
