I'm really going to sound ignorant now but when I first saw the post, I thought it was a wind up. A bit like posting a thread like "What pen is best for flying" and expecting to get silly replies like a "BIC weighs less compared to a Mont Blanc". haha.
Anyway, it seems that this is a serious thread! Am I missing the trick here. Is there a specific criteria of watches that make for good flying other than telling the time?
