  Nonleptonic $\Omega^{-}$ decay branching ratios are estimated by means of the
QCD enhanced effective weak Hamiltonian supplemented by the SU(3) Skyrme model
used to estimate the nonperturbative matrix elements. The model has only one
free parameter, namely the Skyrme charge $e$, which is fixed through the
experimental values of the octet-decuplet mass splitting $\Delta $ and the
axial coupling constant $g_{A}$. The whole scheme is equivalent to that which
works well for the nonleptonic hyperon decays. The ratios of calculated
amplitudes are in agreement with experiment. However, the absolute values are
about twice too large if short-distance corrections and only ground
intermediate states are included.
