The Audemars Piguet Royal Oak Day-Date (Reference 25572SA) is a highly collectible, vintage luxury watch first introduced in 1983. It is famously nicknamed "The Owl" by watch collectors because its twin sub-dials look like a pair of wide owl eyes staring back at you. This specific model combines the legendary sports design of the Royal Oak with a very practical day and date calendar layout.
