The Case, Dial, and Hands
The case of the Replica Royal Oak Tourbillon Chronograph Openworked Black Ceramic is rendered in, well, black ceramic. Audemars Piguet has never been shy when it comes to experimenting with exotic materials in its watches.
To finish a gold Royal Oak case is challenging; to finish a steel Royal Oak case is more challenging, because steel is harder; but to finish a ceramic Audemars Piguet Royal Oak Replica case to look as if it were metal is a feat worthy of applause, because unlike gold or steel, ceramic is brittle and thus not nearly as cooperative.
At 44 x 13.2 mm, the Royal Oak Tourbillon Chronograph Openworked looks like a US replica watch that should feel heavy, and yet with its ceramic body, much of that weight has been mitigated.
Long story short, the dial of the Royal Oak Tourbillon Chronograph Openworked Black Ceramic remains as sexy as it has ever been. The openworking of the dial is done as tastefully as possible and the hit of teal really brings the otherwise monochromatic watch to life.
