If this is anywhere already on here somewhere then I'm sorry. I'm heading to flight school soon and I have sifted through countless pages of forums that have debated which brand of watch is the best or what watch is the best, but what I want to know is how practical is an aviation watch in the aircraft; before I spend a few hundred. I have heard that the kind with the rotating slide-rule bezel that can do fuel calculations, etc. could be helpful, however, I have also heard that your watch is stuck under your gloves and sleeves... so just use the whiz wheel. Any help on this would be great. Thanks.
