The most popular sports watch in the world is ready for its blue chapter. The Audemars Piguet Royal Oak watch has been produced in a dizzying array of ceramic cases since its introduction in 1972. The first Royal Oak Perpetual Calendar made entirely of vivid blue porcelain is now unveiled by the Swiss watchmaker.
The new model features a 41 mm case and matching bracelet that comes in blue ceramic. The day, date, month, moon phase, and leap year indicators on the iconic Royal Oak Grande Tapisserie dial are also saturated in the blue color.

The shade highlights everything, including the inside bezel. Meanwhile, the hour markers and hands applied in 18-carat white gold give the piece a bit of contrast and a luminous coating for visibility.
Zirconium Oxide powder is combined with “binding content” to produce the electric-blue color before being turned into ceramic. Once the components have been sintered at a temperature of more than 1,400 degrees Celsius, they take on their final shade.
The artisans at Le Brassus hand-finished each ceramic part just like they would a piece of precious metal. This means that the blue Royal Oak watch’s ceramic bezel and general design have been enhanced by painstakingly applying AP’s signature satin-brushing and polished chamfers by hand.
The extra-thin self-winding Calibre 5134 that is used inside all current Royal Oak Perpetual Calendars is featured in this new piece. This is a high-end movement, even in leap years, the movement accurately displays the current date while automatically accounting for the number of days in the current month.
The watch won’t require manual adjustment until 2100, as long as it is consistently wound to maintain alignment with the Gregorian calendar. A 22-carat gold oscillating weight with an openworked design is part of the movement, which was introduced in 2015. The Calibre is embellished with circular graining and sunray brushing, which are visible from the caseback.
