Audemars Piguet Royal Oak Perpetual Calendar Openworked Skeleton

This is a very rare Audemars Piguet Royal Oak Perpetual Calendar reference 25636BA.0.0344BA.01 in 18kt yellow gold. This watch was made in a very very limited edition and has been discontinued for many years. This 18k yellow gold case with integrated bracelet has a 39mm case, an open worked skeleton movement that can be seen through the exhibition case back. Does not include box or papers. The condition of this watch is excellent and the case is unpolished. Fabulous watch for any Audemars collector.
