Good shout, I'm always tempted by the military watches on ebay but the amount of fakes has killed the market for me.
Tell-tale signs?
The crowns wrong, it sticks out too far, it should be recessed into the guards by about 40%. The dial looks a much later one judging by the lume colour, the circle around the CWC has been shopped out by the look of things, the lume should be a creamier colour and "puffy", and a 1980 no circle fatboy wouldn't have the crows foot pointing at the crown, it's situated centrally pointing towards the battery hatch, in between the nato stock number and the serial.
Fair point, well made! The overriding thing is they're all too short. :)
