My Asian Bond GMT has a pointy hour hand, not the flatter kind as in the gen. Also, my bezel for some reason has 80 clicks and uses a metal pin on a coil spring to "click" rather than the wire that wraps around like in By-Tor's guide.
Also, the He valve is wrong as everyone knows. There was a batch that had the correct He valve placement.
That's why I voted my Exp2 as closest - I think the only flaws are the crown guards and the non-equilateral GMT pointer, but nobody can spot those without a gen side by side.
