Audemars Piguet has been a master of open-worked or skeleton mechanical watches since the 1930s. Today, it performs it in precisely the same manner: filing, decoration and finishing exclusively done by hand.
Introduced in 2012, the original Royal Oak Tourbillon Extra-Thin marked the Royal Oak's 40th anniversary and was originally available only in platinum, followed by the launch of a yellow gold version in 2016.
Demand from connoisseurs around the world has led to the creation of two new limited edition versions in 2017 - one in brushed 18-carat pink gold with matching bracelet, the other in stainless steel.
