The new Royal Oak Perpetual Calendar in 41mm presents for the first time a case and bracelet fully crafted in blue ceramic. The matching blue Grande Tapisserie dial and subdials further bestow the timepiece with an air of starlit sky. The dial also features blue counters, white gold applied hour-markers and Royal Oak hands with luminescent coating, and a blue inner bezel. The watch comes on a blue ceramic bracelet with AP folding clasp in blackened polished steel.
