Breguet

. . . rose gold or white gold? Thank you. ...  

but it's only a matter of personal preference and the monochrome effect of white gold is very nice too. Best, Emmanuel credit: @orjewellers & A Blog To Watch ...  

It matches perfectly to the white enamel dial!

I really like the rose gold too but white seems more appropriate for this classy and somber piece.

The blue Breguet hands just pop on the white gold version and may be the best true dress watch on Earth!

But only because I don't have anything in rose. Would be ecstatic to have either of them...

champagne problems. You can't go wrong with either. As far my preference, I like white gold, but in this case I would choose the rose gold for the warmth as stated above.

I like the warmth of the rose gold against the grand feu enamel.

...I do prefer the sub-seconds to have 'rounded' edges instead of being sharply-defined...
