Compared to watch altimeters comparable price (sports supermarket, consumer electronics), it has the advantage of following a true watch manufacturer: really solid case and waterproof. Compared to Finland (3-6 times more expensive) products, it has comparable accuracy, better wake but will not loggings nor dascension speeds (that said it is often so complex to use). In short it gives the time and altitude (forget the temperature, which is only used to improve the accuracy of pressure-altitude), made a good awakening and has backlighting, all very accessible. Last, it weighs less than 50g!
