We have had a program of continuous observation of SAX~J2103.5+4545 with the {\em Rossi X-Ray Timing Explorer\/} for more than two years. We have been able to unambiguously count the revolutions of the pulsar over this entire period. We have been able to construct an orbital model for the binary motion of this system which is consistent with our earlier published orbit, but which now includes an orbital period derivative for the system of -5.8\times10-5. We will present detailed results of our orbital analysis, including the results of our search for precession of the orbit. As we refine our orbital model, we hope to observe a dependence of the pulsar accretion torque on the phase of the highly eccentric orbit. This work is supported in part by a grant from NASA.
