there are some 16610 with blue dial and bezel, i just don't know if that is the case with the watch in this picture
I just found this:

ok, when I get the watch back i'll take some more pics, but again, this was not a joke, as I said I'm not here to play games, just to learn some more about watches.
about opening the case back, I'm not crazy yet, I don't know how to do this and I don't intend to do.
but thanks for the replies.
updating, the watchsmith confirmed, it's a gen, not in its best days, as some of you pointed, a lot of scratches and dents, the dial has its flaws, but what the heck, it's a Daytona and now it's mine
btw i'm not here to trick you with a rep watch trying to pass as gen, i really don't know watches and as i said it was passed to me as gen.
to be honest i own a quartz tag f1 (no chrono) and a couple of swatches
i came here really to seek help identifying this watch
ps: sorry for my bad english.
I'll let you know when I come back from the AD, I hope it's not since I received it as gen, but I love reps, personally I could never afford a gen Daytona
