Audemars Piguet Royal Oak 25820ST, Perpetual Calendar, Steel


This “Cosmos” Perpetual Calendar Royal Oak 25820ST features a striking combination of the iconic Royal Oak case, an unusual indigo blue dial and a perpetual calendar movement central to the manufacture’s history. Housed in stainless steel, it embodies much of the spirit and innovation which carried Audemars Piguet forward in the second half of the 20th century.
