  We present a model based on the flavour group S3 X Z3 X Z6 to explain the
main features of fermion masses and mixing. In particular, in the neutrino
sector the breaking of the S3 symmetry is responsible for a naturally small
r=\Delta m^2_sol/\Delta m^2_atm and suitable next-to-leading order corrections
bring \theta 13 at the level of ~ 0.13, fully compatible with the recent Daya
Bay result. In the quark sector, the model accommodates the different mass
hierarchies in the up and down quark sectors as well as the Cabibbo angle and
Vcb (or Vub, depending on the charge assignment of the right-handed b-quark) in
the correct range.
