Default spiral spring: am I drawning in a glass of water?

Drawing a spiral coil: before I tryed I was bluntly sure that a few mouse clicks would do it. Now I'm not as sure anymore.
Mind you, not a helicoid, a true spiral: the radius gradually increasing or decreasing, but all on the same plane - the kind of spring you still find in old-fashioned mechanical clocks or toys.
