rhodium - more classic and goes better with all stainless steel
If you have parts of your watch as rose gold, then the pink dial would be something of consideration which I had contemplated on as well.
Which one is the "wave pattern"? The one with Rolex written all over? I dunno about this, my AD advised against it as it's very difficult to see. So if your eye sight is not very good, or if you're like me, very impatient and I need the time STAT with just a quick glance, I won't go for any fancy patterns or what not.
Best of luck!
