I have to say it's pretty amazing how good these reps are. I have a hard time telling them apart. On the gen I think the white in the lume is a little whiter in daylight. I think the raised portion of the dial is a lighter black on the gen. Gen has softer rubber strap, bezel feels more solid, and crown feels much more solid. The titanium maybe has a slightly lighter hue. It's so hard to tell.
There are things I thought were flaws on the rep that are actually spot on. Things like the L in Co-Axial. Seems weird to say considering I just bought it in gen but this is definitely NWBIG.
Gen on right. Crown is out on the rep in all pics.
Anyone know why it won't let me upload imgur pics? Until I can figure out how to embed them, here's the link to the album:
