Amazing what you read on R.A.S. sometimes ;-)

Maybe it's just personal preference. I have both a digital and a
traditional altimeter and find myself using the round dial exclusively.
Like wise, my current watch has hands. I much prefer it because I don't
have to read it - just scan it.

Slightly off topic, I remember reading about a (pre-digital) military
transport where the flight engineer's station was designed so that when
everything was operating normally, all dials pointed in the same
direction. It almost trivialized detecting abnormalities.
