A measurement of the partial width ratio GAMMA(bbBAR)/GAMMA(had) using a method which tags the Z --> bbBAR decays through the lifetime of the produced heavy hadrons is presented. This method relies on the tracking precision afforded by a double-sided silicon vertex detector. The tag algorithm makes a probabilistic interpretation of three-dimensional track impact parameters, using the data to measure the resolution. By tagging the two b hadrons separately, both GAMMA(bbBAR)/GAMMA(had) and the tag efficiency can be determined from the data. For a 26% efficiency of tagging a single b hadron within the vertex detector solid angle coverage, a purity of 96% is achieved. A value of GAMMA(bbBAR)/GAMMA(had) = 0.2192+/-0.0022(stat.)+/-0.0026(syst.)+/...
