SMC X-1 is a short spin period (0.70 s) X-ray pulsar accreting from a massive B0 supergiant companion. It is unusual in that it has exhibited one probable Type II X-ray burst, possibly putting it in a class with GRO J1744-28 (``The Bursting Pulsar''). It has also shown smooth spin-up since its discovery, despite varying in luminosity from 10^37 to 10^39 erg/s. It is also an X-ray eclipsing system and the orbital period derivative has been measured. The USA experiment on ARGOS made 664 separate pointings at SMC X-1 between 1999 October and 2000 November (covering roughly 4 of the 60-day disk precession periods), as part of a program to carefully monitor the pulsar's timing properties. We present an analysis of these observations combined with archival data from RXTE. We study the torque variations observed and examine the power density spectrum in the range 1 to 15 keV.
