In fact, you are both right, write the macro differently.
\def\repere{\bigl(O\,;I,J\bigr)}
\starttext
\dorecurse{2}{blabla} $\repere$ \dorecurse{2}{blabla}
\dorecurse{2}{blabla} $\bigl(O\,;I,J\bigr)$ \dorecurse{2}{blabla}
\stoptext

I did not know it because, before migrating to context, I used latex with this : \newcommand{\repere}{$\bigl(O\,;I,J\bigr)$.
In LaTeX there is no space neither:
--8<---------------cut here---------------start------------->8--- \newcommand{\repere}{$\bigl(O\,;I,J\bigr)$} \documentclass{article} \begin{document} x \repere x \end{document} --8<---------------cut here---------------end--------------->8---
