AP Diver: Adjusting the bezel under water...

It is used to time bottom times and deco stops (according to your dive plan). Air times would vary wildly depending on several factors such as depth, how agitated you are and so on ... Technically, you plan your dive, stick to it (dive your plan) and all is good ... that's why you need to measure times (how long you stay at different depths, how long do you need to stop for decompression, etc.) ... so you would need to adjust under water. As many said, I am not sure I would do this with the AP Diver ...

In reality, you just use a dive computer (I do anyway).

It is pretty nice to time pasta though :)
