I use
\usepackage{amsmath}
\numberwithin{equation}{chapter}
It means when I make an equation. I just need to do this
\begin{equation}
equation
\end{equation}
And it's numbered automatically.
So how can I cross-reference the equation numbered (1.2)? I don't \label
it, so \ref
is not helpful.

You need to run LaTeX at least twice.
Addendum: From comments to your question and changes of question follows, that you actually not interested referencing mechanism ... An alternative is using
tag
s for numbering/tagging of equation and than referencing it manually:Result is the same as before.
