Ive taken my GT into 2 AD's just for the hell of it...I park in front with the SL which must help.....and it never comes off the wrist...never had an issue...the guy was bluffing...no way he could call it fake 100% on the wrist after his other comments...no way no how. Ive put my GT next to the gen...it is VERY VERY close and the feel is 98% the same...except the bezel which is still close...just a little smoother on the rep lke it was lubed. My good friend has a genuine B for B and he thinks my GT is real as well. I would have said "Wow, fake huh? You must not know much about genuine Breitlings"...and then walked away. Either way I think he caught on that you were worried he knew it was a fake and he just went for it and held to his word until you took it off. Im very suprised he had the nerve and the lack of class to do that in the first place.
