We present a precise determination of the leptonic decay constant F_D(s) of the D(s)-meson in quenched lattice QCD. This work is particularly focused on the analysis and discussion of all sources of systematic errors. We simulate directly at the physical quark masses for five different lattice spacings between 0.1fm and 0.03fm using O(a)-improvement. The finest lattice is still work in progress. After taking the continuum limit and setting the scale with the Kaon decay constant F_K=160MeV we arrive at a value of F_D(s)=252(9)MeV. Setting the scale with the nucleon mass instead leads to a decrease of about 20MeV of F_D(s).
