I have a Hamilton Aviation QNE w/ strap and bracelet up for trade. This piece was purchased from an AD last summer, and has been worn minimally (maybe 12 times). I'd say it is 90 to 95% given it has some scratches on the under side of the lugs from swapping the bracelet to a strap...and subsequently the bracelet has some hidden scratches near the lugs... you'd never see the scratches while wearing the watch. The sapphire on this puppy is absolutely gorgeous! I'd like to get a JSAR on bracelet, but a GSAR on bracelet might do the trick too... really I'm after a nice diver, so make me some offers if you like the looks of the Hamilton... Marathon, Oris, Nauticfish, Ocean7... I love "tool" divers so if you have one you want to trade lemme know!
