I heard long ago that it's easier to remember analog time after a glance at a watch. How often do you glance at a digital watch, someone will ask you what time it is, and you have to look again? That doesn't happen as often with analog time. You don't know the exact time, but you'll remember "quarter after" or similar. This was way back at the advent of digital watches and I don't know if that idea has stood the test of time, so to speak.
