  Following the procedure and motivations developed by Richardson, Buchmuller
and Tye, we derive the potential of static quarks consistent with both the
three-loop running of QCD coupling constant under the two-loop perturbative
matching of V and MS-bar schemes and the confinement regime at long distances.
Implications for the heavy quark masses as well as the quarkonium spectra and
leptonic widths are discussed.
