New GMT-II incoming -- some q's re: authenticity

[alelser]

[Mods, if this thread belongs elsewhere (or not at all) I apologize in advance.]

So, I have a new (to me) GMT Master II, Y-serial incoming that I am excited as all get-out about. I have confidence in the seller's integrity, but am still a bit scared of the super-fakes that are out there (what if the seller got duped and never knew?).

I had the seller take some detailed pics for me, and the serial number and ref number engraving look nice and crisp (one, clearly engraved line, no blasting or etching). The hands are in the proper proportions as best I can tell... all the easy tests passed.

My question is this: once it is in my hands in the next day or so, are there any tests that don't require removing the caseback (no access to a removal tool, and not sure if any of the jewelers in my small town would have one) that would help me know that is isn't a "superfake?"

I have access to a precise jeweler's scale and know that the GMTII should come in at 127 grams. Can anyone tell me how many bracelet links this should include?

Not wanting to give the counterfeiters any more info than they already have, I am open to private messages on this topic.

Just trying to set my mind at ease.

Thanks in advance,
