Audemars Piguet Royal Oak Perpetual Calendar Openworked Black Ceramic

At SIHH 2019, Audemars Piguet reveiled a new boutique edition Royal Oak Perpetual Calendar Openworked Black Ceramic Ref. 26585CE.OO.1225CE.01. 

Royal Oak Perpetual Calendar Openworked Black Ceramic 2019

This year's Royal Oak comes openworked with sapphire dial. A unique presence in which the new self-winding caliber 5134 inherited from the caliber 2120 is wrapped in a glossy black ceramic. And the black ceramic case, the blue of the moon disk, the pink gold shine scattered throughout the spot, such as the hour markers and hands, each draws an exquisite contrast.

Two years ago at the Only Watch 2017 charity auction, the unique timepiece was reveiled to the world, executed entirely in black ceramic, including caseback and bezel - the Audemars Piguet Royal Oak Perpetual Calendar Black Ceramic Piece Unique ref. 26599CE.OO.1225CE.01
