We build an S-4 model for neutrino masses and mixings based on the selfcomplementary (SC) neutrino mixing pattern. The SC mixing is constructed from the self-complementarity relation plus delta(CP) = -pi/2. We elaborately construct the model at a percent level of accuracy to reproduce the structure given by the SC mixing. After performing a numerical study on the model's parameter space, we find that in the case of normal ordering, the model can give predictions on the observables that are compatible with their 3 sigma ranges, and give predictions for the not-yet observed quantities like the lightest neutrino mass m(1) is an element of [0.003, 0.010] eV and the Dirac CP violating phase delta(CP) is an element of[256.72 degrees, 283.33 degrees].
