I consistently keep my rep collection between 5-10. Anything more, I find myself not wearing it, growing tired of it and thus, selling it. I keep a pretty good rotation -- and peaked interest -- with 5-10.
So...top 3 flaws for this rep:
1) Case not ti
2) Incorrect size (rep:44mm gen:47mm)
3) Rubber strap (gen has ti bracelet)
I think that captures them all...dial looks pretty good, as does AR.
