Is there any difference in accuracy between digital or analog quartz watches?
Quartz watches are said to be on average accurate to about 15 seconds/month, but they don't mention whether that's for digital or analog quartz watches. Is there a difference?

the quartz crystal oscillator determines the accuracy. The display can be numbers (digital) or moving hands (analog), makes no difference.

It really depends on the quality(price) of the watch. Some mechanicals are very accurate in a controlled environment but when it gets cold(you go skiing) they slow down.
Some digitals are very accurate if they have a very precise crystal.

I have a 25 year old Seiko quartz watch with an analog dial. It keeps time in terms of less than 5 seconds per month. I am sure a digital version would appear more precise but that is just a matter of time.

Difference is in display.
The heart of every quartz clock is small quartz crystal that acts like tuning fork (it is actually shaped like one). It vibrates with accurate frequency in ultrasonic range, usually around 32kHz. This vibrations give away electric pulses.
What happens next is that pulses should be somehow counted and converted to useful display which shows time. How the counting is done depends on whether clock is analogous or digital. Analogous clocks utilize stepper motor that rotates in small increments and moves the hands. Digital clocks have digital counter circuit which shows numbers on LCD or LED display.
What is in common to both kinds, besides quartz crystal, is that they are electrical - powered by batteries or other source of electricity.
