Reference 4187BC is an ultra rare gem set variant of the iconic Royal Oak jumbo ref 5402 of which only 10 were ever made in white gold (according to the AP Chronicles published by Audemars Piguet). So rare is this model that to the best of our research the last example to grace an international auction room was sold at Phillips Geneva in November 2020.

Audemars Piguet’s Royal Oak does not need an introduction. With its launch in 1972 Audemars Piguet created one of the most iconic and classic wristwatches of the late 20th century and a benchmark for what the luxury sports watch should be.

Even though the model was intended for leisure wear, Audemars Piguet nevertheless created a few examples in precious metals and even added a touch of flamboyance with the addition of diamonds. Collectors are familiar with the reference 5402BC in white gold with diamond markers on the dial, but with the present reference 4187BC Audemars Piguet upped the ante by adding a diamond-set bezel (8 diamonds per side) to its iconic model adding a touch of louche decadence to the Royal Oak now wonderfully idiosyncratic with its sporty look yet glamorous livery. Crafted out of solid 18-karat gold, its luxurious heft is dramatic, especially when compared to the regular production stainless steel versions.

The present ultra-rare example is fresh to the market, offered by its original owner and not only in excellent condition but also a super early example bearing number 085.
