I have one of these it was 2nd rep purchase, they really are a very good watch and I don't think the display back is an issue.
These are quite large faced watches but so very thin. Very stealth wealthy.
I woukd suggest trying on of these, mines on a black strap and even that's good quality. Seriously for $100 you aint got much to loose.
Just my opinion
