Baltany - Military Style Khaki Aviation Pilot Watch S2076, $165 Hamilton Pilot Pioneer Alternative 

It's a countdown bezel, so instead of measuring time out from a set start for oxygen management, like a dive timer, you're measuring to a set end point, like needing to arrive at a checkpoint by a certain time.

Not everyone can afford the Hamilton. Try less of the ‘crappy’ and you won’t appear be so much of a ‘fool’.

@@JamesAlexander14 what on Earth does that have to do with my comment? You not being able to afford the watch has nothing to do with how unnecessary the length of this video is...are you okay?
