Both are great, I have noticed that I have two prefrences maybe because I am getting older.:scared: I like the 14k with the nice clean dial. For some reason the black is harder for me to read especially at night.:001_smile:
I prefer stainless over gold, just for the fact I am a bit hard on watches, and gold is to soft a metal for me. I may someday get a two tone, or if I ever get the grail (WG DD); but, overall, stainless is for me the best option.
I'm pretty sure that you can get just about any dial combination through Rolex. I have to be in good light and have both examples in front of me to see the difference.
I love the idea of 18K and higher purities, but they aren't very good to wear as the soft hold really shows scratches and dings. They can also show bracelet stretch early as the gold is heavy. For wearing around, 14K is just so much more practical.
