We have analyzed archival spectroscopic observations of Markarian 3 taken over the last 12 years with the XMM-Newton, Suzaku and Swift observatories, as well as data taken during a monitoring campaign activated by us in 2012. The timescale of the Compton-reflection component variability (originally discovered by ASCA in the mid-'90s) is ~64 days.
