The votes have been counted and the results are in. The winner of watchmaking's most prestigious industry award is the Audemars Piguet Royal Oak Selfwinding Perpetual Calendar Ultra-Thin. This is the serially produced, commercially available version of a watch that readers may remember from its initial debut as the Royal Oak RD#2. Presented at the SIHH 2018, it was made of solid platinum and was an experimental prototype.
Today's winning watch is made from titanium with a platinum bezel and polished platinum bracelet interlinks. Like the RD#2, the Royal Oak Selfwinding Perpetual Calendar Ultra-Thin measures just 41mm x 6.3mm with a perpetual calendar movement that clocks in at just 2.89mm thin. These record-breaking proportions were achieved by taking the classic, three-level perpetual calendar construction and and compressing everything into one layer, as seen in the below image. The Royal Oak Selfwinding Perpetual Calendar Ultra-Thin is an incredibly impressive watchmaking achievement, and one that clearly impressed the Grand Prix jurors in Geneva.
Though AP has won several GPHG awards across numerous categories, this is the company's first time taking home the top prize.
