i had the Sub about 5 days before dropping it off at RSC, so it's hard for me to compare. i recall being surprised how "flat" the bezel felt; the Exp II bezel has a nice slope away from the crystal.
oh, i felt oddly conspicuous wearing the Sub. i've never gotten that feeling w/ the Exp II or OP. part of it was me catching someone staring at it, with (what i felt was) obvious recognition. made me paranoid for just a moment, actually. that also surprised me. i reckon after putting it on a strap that won't be as common.
