A dial gauge can impart certain information that other ways cannot. I can notice a sudden change in movement without looking directly down, or see certain patterns of movement that simple numbers won't. An old example of the loss of that was found in some classic luxury cars (my grandmother had a Cadillac that I noticed it in). The speedometer wasn't a dial, it was an analog bar that would go right to left as your speed increased. It was very hard to judge change of speed by this, much like it's hard to see from a few digital numbers that rapidly change. I've also noticed that even digital dial gauges can suffer from this if their refresh isn't fast enough to simulate an analog accurately.

Doesn't mean you can't get used to a display or find other ways to get the same input, but dials aren't just old nostalgia, they do have advantages. I would bet for some measurements an analog multimeter is preferred over a digital, and vise versa.
