We give a detailed description of the measurement of the W boson mass, M-W, performed on an integrated luminosity of 4.3 fb(-1), which is based on similar techniques as used for our previous measurement done on an independent data set of 1 fb(-1) of data. The data were collected using the D0 detector at the Fermilab Tevatron Collider. This data set yields 1.68 x 10(6) W -> ev candidate events. We measure the mass using the transverse mass, electron transverse momentum, and missing transverse energy distributions. The M-W measurements using the transverse mass and the electron transverse momentum distributions are the most precise of these three and are combined to give M-W 80.367 +/- 0.013 (stat) +/- 0.022(syst) GeV = 80: 367 +/- 0.026 GeV. When combined with our earlier measurement on 1 fb(-1) of data, we obtain M-W = 80.375 +/- 0.023 GeV.
