...if you're seriously flying IFR I have yet to see an aeroplane that doesn't have a large clock with sweep second hand, built in right in front of you.
Well, I'm regularly flying around ten aeroplanes (SEP and MEP for IFR training and three different Citations) and _none_ of them (not one!) has an analog clock. I can't even remember when I last flew in an aeroplane with a (working) analog clock.
