Looking over the watch, I've found (and done some research for you)
Bracelet looks gen
back in the 90's the link rep bracelets looked like this
I.e individual links were not 2 pieces but one, with a groove to make it look similar. some of the less quality reps still have this today.
if it's the older model from 80's/90's it should also say 'T swiss made T' not 'swiss made' like they do nowadays. so that could be something to check for.
but the biggest tell will be the model number, they are usually always incorrect on the reps. This looks to be 3rd or later generation S/EL model (Sports Elegance) from what I can tell, and the serial on the back could be WG 1522-0 otherwise, it will be around WG 1400 - 1530. The 1st gen professionals didn't actually say professional on the dial. and up until the 2nd gen, all the dials were flat. notice yours has a ring that is depressed. the first/second gen models started with S. 9x so that might also help determine the year but because of the 3d dial im going to say its not pre 90's.
1st gen
If the model number is correct then this model is from the 90's and if it's in pristine condition they are quite a collectors piece. If you want to be real picky to make sure, the bezel should have 60 grooves, and the crown should have 22.
As for the box, looks like one of these:

And if it is, and it's included, that box is $500+ alone....
If its in great condition, and with that box (if it says TAG Heuer inside) id say it could go for $800+. without the box, you are looking at maybe $500+ all depends how many people are interested, and what the condition is like.
Also as stated by T4D, It is a quartz, none of these models were automatic AFAIK. before you bid, see if you can look inside the case back, cause old watches with old batteries do not go well together. make sure the movement is in good condition.
