This timepiece features a 39mm case crafted from titanium, complemented by a polished platinum bezel. It is powered by the self-winding Caliber 2121, a movement known for its slim profile and historical significance within the Royal Oak series.

For collectors, the 15202IP holds interest as a limited production model that bridges traditional Royal Oak design with contemporary material experimentation. Its use of titanium and platinum, combined with the Caliber 2121, positions it as a distinctive piece within the broader Royal Oak Extra-Thin lineage, appealing to those who appreciate material innovation and the historical context of its movement.
