I prefer YG, but it sounds like you prefer the WG more! It doesn't matter if you have a variety in your watch collection - get whatever makes your heart skip a beat!
Have you considered a two toned Rolex? It seems like a classic Rolex look KWIM? You can wear with both your plat and yellow gold. Just a thought. What a wonderful dilemma to be in and a sweet hubby you have!
Purse I just got the yg president with white face and love it! If you go for the president, I'd suggest that combo. For the prarlmaster, definitely go white gold...I also tried the rg president and was underwhelmed.
I also wanted the "perfect" watch wardrobe. I ended up with the rolex yatchmaster in platinum/ ss for sporty, the happy diamond chopard with diamond bezel for dressier and the yg president ...um... For yellow gold!
