It's certainly common to find these gaudy blinged-out DJs, so the case and movement are plausibly authentic, but it's impossible to tell from the photo. The dial appears to have an outer step, so perhaps this is a modified 4-digit DJ, like a 1601, which would have a non-quickset 1570 movement. It's even possible that the dial is authentic but modified, although it's ruined in any case.
