A proton-proton collision data sample, corresponding to an integrated luminosity of 3 fb-1 collected by LHCb at √s=7 and 8 TeV, is used to reconstruct 63 ± 9 Ωb- → Ωc0π-, Ωc0 → pK-K-π+ decays. Using the Ξb- → Ξc0π-, Ξc0 → pK-K-π+ decay mode for calibration, the lifetime ratio and the absolute lifetime of the Ωb- baryon are measured to be τΩb-/τΞb- = 1.11 ± 0.16 ± 0.03, τΩb- = 1.78 ± 0.26 ± 0.05 ± 0.06 ps, where the uncertainties are statistical, systematic and from the calibration mode (for τΩb- only). A measurement is also made of the mass difference, mΩb - mΞb-, and the corresponding Ωb- mass, which yields mΩb - mΞb- = 247.4 ± 3.2 ± 0.5 MeV/c2, mΩb- = 6045.1 ± 3.2 ± 0.5 ± 0.6 MeV/c2. These results are consistent with previous measurements
