Bobby, all pool balls or billiard balls are the same size but will vary in colors but all are numbered. Snooker balls are smaller in size and play with mostly red balls and a couple odd ones. I do not play snooker. My point is take one of yours and set it so the number reads just like you have straight up and down. Now rotate it 180 degrees left to right and does the number on the opposite side show upside down? All billiard balls I play with and have are this way.
Need to make a correction here. Most everyone associates billiard balls and pool balls as the same ball and I am one of those. I watch billiard tournaments and they too call them that. But fact is pool balls measure 2-1/4" and billiard balls are 2-7/16". Pool balls are numbered but billiard balls are not I do not play so called billiard games. Maybe I need to stop calling these billiard ball clocks and call them pool ball clocks.
