Altimeter. Wherever you have a barometer, you usually have an altimeter, as well, since it is possible to calculate altitude by measuring atmospheric pressure. The range is -400 meters (-1300 feet) to 9000 meters (29,500 feet) with a resolution of 1 meter (3 feet). Chronograph. Resolution of 1/100 of a second, maximum time of 9:59':59". The T-Touch's stopwatch can record a single split time. Alarm. The alarm is a daily alarm -- nothing special -- though it is nice and loud, which I really like. The only thing I don't like about the alarm is that the only way to set it is by incrementing or decrementing minutes which can get a little tiresome if the time you want to set it to is 12 hours away. Fortunately, the minutes do speed up the longer you hold down the buttons (there are three different speeds) which makes it better, however I would rather be able to set the hours, minutes, and meridian separately.
