Royal Oak Perpetual Platinum/steel
This is my favorite version of the non-skeleton RO Perpetual. It was made in very limited production more than a decade ago. In fact, this exact version is the one that Giulio Papi himself wears daily.
It has several unique features. The bezel and inner bracelet links are high polished platinum so it really pops. The dial has silver rings which give an extra layer of depth and legibility. It also has a very cool and unique black rotor.
This particular piece had a full factory service in Nov 2015. It’s in 95% condition and comes with the service papers, AP Cert of Authenticity, and box.
