| Summary:
We report on a measurement of the $Omega_c^0$ lifetime using $Omega_c^0 to
Omega^-pi^+$ decays reconstructed in $e^+e^-to cbar{c}$ data collected by
the Belle II experiment and corresponding to $207~{rm fb^{-1}}$ of integrated
luminosity. The result, $rmtau(Omega_c^0)=243pm48( stat)pm11(syst)~fs$,
agrees with recent measurements indicating that the $Omega_c^0$ is not the
shortest-lived weakly decaying charmed baryon.
