Clocks used a base texture for the body of the clock, as well as "dial.png", a separate texture, which was the animated portion indicating the time.
According to the wiki there were 228 visually distinct clock sprites that could be generated this way. Something potentially worth answering is how many actual sprites were possible internally, including visually identical cases? 228 is reasonably close to 256, so I'd assume that, but I can't be sure.
