Two Royal Oaks from the same era. Openworked Perpetual Calendar reference 25829PT, and the other piece being 25820ST with silvered dial. I love the thinner bracelet (even thinner than recent Extra-Thin versions). Feel free to follow me on IG, @openworked....
I am especially fond of the 25829PT, you know you are wearing a watch when it is on your wrist. I have the last two versions of the 15202’s, while the current version is thicker the clasp is much more comfortable.
The added heft of platinum is nice. To me, this watch has everything... beautiful finishing and engraving, openworked, complicated and in precious metal. In 39mm. It doesn’t get much better!
