the RG hue of RM stands out quite a bit and serves as a nice contrast to the stark simplicity of both the 005 and 010, both the "simpler" models of RM. For more complicated pieces, I prefer TI or Alusic
Got the RG first. Loved the watch but the RG didn't grow on me. I love the titanium. It's the most comfortable watch I have ever worn and I guess I just prefer the look of white metals.
