My gut feeling is that this one is actually OK.
I own the same model with silver dial that I bought NOS in the late 80s (with purple snort still on the back).
Only difference I can see to mine (despite the dial color and slightly different hand lume inlay) is that this one still has tritium.
Otherwise all the details look the same.
I would be surprised if someone put that lot of effort in falsifying such a relatively cheap watch.
