Handled both during Geneva watch days (even though not at the same time, so no side by side comparision). In my opinion, the blue one looks more modern and sporty. The mirror polish is more noticable and the blue pops a lot more (maybe even too much, depending on what you‘re looking for.) The rose gold is more elegant, balanced and restrained. Would be very difficult for me to make a decision as I don‘t own one, but if I‘d already own one (no matter which), I wouldn‘t switch.
