This is what I heard and meant as well. If you buy a watch in RG, would you not want it to stay that way instead of turning YG.... I know I would. If it was my choice, I would prefer WG with diamonds in Ballon over RG. My current collection consists of all Cartier watches after all ( Tank Americaine w/ diamonds in YG and Tank Francaise w/diamonds in WG). I used to have a WG Panther as well that I loved to death and wore a lot, but had since sold it. I need to make some way for a couple of Rolexes!!!
