  The mass of the W boson is determined from the direct reconstruction of its
decays into purely hadronic and semi-leptonic events in e+e- collisions at LEP.
The data sample corresponds to an integrated luminosity of 683 inverse
picobarns collected with the ALEPH detector at centre-of-mass energies up to
209 GeV. To minimise any effect from colour reconnection a new procedure is
adopted in which low energy particles are not considered in the mass
determination from the purely hadronic channel. The combined result from all
channels is Mw = 80.440+-0.043(stat.)+-0.024(syst.)+-0.009(FSI)+-0.009(LEP)
GeV/c**2 where FSI represents the possible effects of final state interactions
in the purely hadronic channel. From two-parameter fits to the W mass and
width, the W width is found to be Gw =
2.14+-0.09(stat.)+-0.04(syst.)+-0.05(FSI)+-0.01(LEP) GeV
