  We explore the possible existence of the $J^{PC}=1^{+-}$ counterpart of the
$X(3872)$ state in a coupled-channels calculation within a constituent quark
model, with the aim of confirming the existence of the so-called
$\tilde{X}(3872)$ state observed by the COMPASS Collaboration. Two states are
found in the energy region of the $\tilde X(3872)$ signal, both with almost
equal mixture of $c\bar c$ $2^1P_1$ state and $D^*\bar D^{(*)}$ channels: One
that can be identified as the dressed $c\bar c$ $2^1P_1$ and a bound state
below the $D\bar D^*$ threshold. We provide predictions of strong and radiative
decays that could help to clarify the existence of such structures.
