NGL, wind up analog clocks are useful in places where the power goes out often. I have a 7-day grandfather clock and it's been a godsend when northeasters turn into ice storms that take down the power for days..

(Northern New England has wretched winter weather some years)

It's an easy way to introduce fractions, especially since it's common to hear/say it's a quarter passed 2, half passed 5, and a quarter to 9.

Also teaches multiples, since the numbers on the clock represent multiples of 5.

Helps with directions, clockwise is when the hands spin to the right and counter-clockwise to the left. You'd be amazed how many students can't tell their left from right.

Of course it's still needed. There still exist analog clocks almost everywhere. (At least in my country)
