We present the measurement of the two-neutrino double-$\beta$ decay rate of $^{76}$Ge performed with the GERDA Phase II experiment. With a subset of the entire GERDA exposure, 11.8 kg yr, the half-life of the process has been determined: $T_{1/2}^{2v} = (2.022 \pm 0.0018_{stat} \pm 0.038_{syst}) \times 10^{21} yr$. This is the most precise determination of the $^{76}$Ge two-neutrino double-$\beta$ decay half-life and one of the most precise measurements of a double-$\beta$ decay process. The relevant nuclear matrix element can be extracted: $M_{eff}^{2v} = (0.101 \pm 0.001)$.
