AP Royal Oak Chronograph

[deweque]

Hi, i am planning to purchase my 1st AP this month. However im still wondering whether to choose AP Ro Chronograph or AP Roo Panda.

For me, i am more attracted to the AP Ro chronograph, since its a beautiful timepiece with classic and elegant style. However, i would prefer watch that has leather strap instead of stainless bracelet.

Can anyone help me to answer and give their opinion...
1. Which one would you prefer Ap ROC or Panda?
2. Since the Ap Roc comes up with bracelet, is it possible for me to change into leather strap ? Since some people said that there are some issues in replacing the bracelet...
