The case reference is a stainless (starting with 2), and it has rose gold lugs and bezel. The rose gold color is the same on the sides and back of the lugs as the front, and there is no sign of any plating loss anywhere on the bezel or lugs. I believe when UG did combination cases like this, it's usually solid rose gold? Am I correct in this understanding, is there any way to verify this (short of taking to a jeweler and having them test it?). I will include a few pics, but please note its very hard to photograph the rose gold as it often ends up looking like stainless, especially the shot from the rear.
