instruction: What is Audemars Piguet Royal Oak ?
response: Audemars Piguet Royal Oak is a luxury watch. This watch was invented in 1971 by Gérald Genta and presented at the Bâle exhibition. It is the first steel watch at the price of a gold watch. It is recognizable to its specific octagonal shape and its handmade dial representing a « petite tapisserie ». It is also one of the first watches with a bracelet integrated into the case. This first Royal Oak had 2 hands (hours, minutes) and the date. It is also called Jumbo because of its imposing size for the time: 39mm in diameter. This watch is an icon for all collectors. It is now available in several versions (size, complications, thickness).
