2012/01/20 - Audemars Piguet new Royal Oak Selfwinding

The Royal Oak selfwinding watch appears in a new more contemporary 41 mm dimension, replacing the current 39 mm size. It is available in steel and pink gold versions. Its dial has been revisited to accentuate the “family likeness” that makes each Royal Oak so immediately recognisable.
