Few luxury watches have had as much impact on the horology world as the Audemars Piguet Royal Oak. First introduced in 1972, the Royal Oak revolutionised the industry by proving that a stainless steel sports watch could be just as prestigious and expensive as a gold dress watch.
Designed by the legendary Gérald Genta, the Royal Oak’s distinctive octagonal bezel, exposed screws, and integrated bracelet have become instantly recognisable symbols of luxury.
Beyond its aesthetic appeal and craftsmanship, the Royal Oak has also emerged as one of the most substantial investment watches. Over the past decade, key references have appreciated significantly, with some models seeing annual value increases of 15–30%.
With demand consistently outpacing supply, the Royal Oak remains a highly sought-after timepiece among collectors and investors. If you’re considering an Audemars Piguet Royal Oak as an investment, these are the best models to buy in 2025.
