I have two Breguets - one in yellow and the other in white gold. The dials of Breguets are so elegant I think they actually look better with yellow gold.
I asked this forum about what to choose, so here are the pictures of the result. I am wearing it for a day and I can say - this is a nice watch. I took these pictures of the hand of a "warm-from-wrist" watch. Someday I will probably make a quality picture...
