Select the next number, 2, and choose the rotate tool in the toolbox. Opt/alt click on the center of the baseline of the numeral to set the point of orientation. To keep the numbers rotated in proportion to the hour marks, add 30¼ for the rotation. That means you rotated 1 by 30¼, so you rotate 2 by 60¼. Enter 60 in the angle box and click OK.
Continue in this manner, adding 30¼ of rotation to each number around the clock face. (3=90¼, 4=120¼, 5=150¼ and so on up to 11=330¼). When you are done, some of the numbers will be too close to or even on the clock face depending how far from the original circle you placed your first 12.
