Follow this tutorial and you will find out how to draw a clock that goes round and round to the infinite with the help of Adobe Illustrator’s Art Brushes. You will also learn some tricks on how to make all the hours and the divisions to fit perfectly.
Start by opening a new web document then draw a 500 x 400 px Rectangle that will define your working space. Now take the Spiral Tool and draw the first spiral like the pink one in the image. While drawing the spiral press the Up Arrow key on the keyboard to create more segments. When you are done draw two more spirals or just scale the first one and make sure they are centered at the end.
