On my wrist was the yellow gold with diamonds in small size. In my opinion, Panthère in midsize looks more modern than the small size. I’ve the small wrist (15 cm) and still found Panthère small very tiny.Thanks! Is this SS with pink gold and diamonds that you have on? How did you like SS with YG plain (without diamonds)? Can't wait to try it on! Are you going to get mid size SS with diamonds? Great choice!!
For materials, I’m in love with stainless steel. But the YG is very feminine and dressy. You cannot go wrong with either

The diamonds option depends on your preference and budget. I’m the one who prefer the shining light of diamonds on the watch, even my limited budget lol. And yep, I plan to get SS in midsize with diamonds in the very near future.
I attached herewith the photo comparing from left to right fyi : YG small size, SS midsize and Tank Français small size. All models are with diamonds.
