Acording to my further research, here are the conclusion for now. see the gen pictures below.
For the 5177 SS Plaid texture dial with leather strap model: The number on the dial should be 3934 not 3944. Black color date font and white background is correct for this 5177 Ss Plaid texture dial model.
3944 is correct only for yellow gold case. Black color font and white background is correct for this model. Therefore, if YG is available then it could be a super rep.
For the 5177 SS Plaid Texture dial with SS bracelet and 5177 RG plaid texture dial with leather strap: the number on dial should be 3334 and the date font should be blue and white background.
For the 5177 SS dot texture dial with laether strap: the number on dial should be 3464 and the date font color should be blue and silver background.
