As you probably know, there are kits available to make these watches with the addition of a legit movement. I don't want to post links, but if you google, you can find sales listings for those kits. You should compare your dial printing and case engraving, case shape, shape of the hands, shape and position of lume plots, fonts on the bezel, etc., to known correct examples. It's also good to look at the outside case-back engravings. I think you will find some very obvious differences. There are a number of threads on the topic.
