This is one of my favorite ProTreks. Very easy to read at night and the buttons work well if you have gloves on.

You hang out above 32,000 feet much?
These watches with the newest generation sensor are actually quite accurate. There are a lot of people who don't understand how to use them though. Especially how barometric pressure changes will affect altitude. They think it's not accurate because the altitude drifts over time. Learning how to use your equipment is key.
