The Highgear Alterra is a real value compared to other altimeter watches in this price range. Just hold it side by side with the Suunto Vector and the ruggedness of the Alterra is made obvious by the steel back. There are also more functions which can be a pain when scrolling but this is minimized by being able to access altitude and barometric readings (including graphical) from the time function. Scrolling through the functions is only necessary when seeking more detailed information. I have not been to altitude yet so cannot attest to the accuracy over time, but I am more than pleased so far by the quality construction and function of the Highgear Alterra.
