Introducing the Royal Oak Perpetual Calendar 41mm

Audemars Piguet launched the new, larger 41 mm diameter versions of their revered Royal Oaks in 2012, which we reviewed HERE. Staying consistent, the newly announced Royal Oak Perpetual Calendars have also been upsized to 41 mm diameter cases.


The new collection will be available in 4 variations. Steel with a white or blue dial and pink gold with a white or blue dial.

According to the manufacture, “The enlarged size has resulted in a “Grande Tapisserie” dial design that greatly increases the overall aesthetics, balance and legibility of the perpetual calendar indications.”


The perpetual calendar features the day, date, a highly detailed astronomical moon display, month and leap year. Uniquely, the outer chapter ring displays the 52-weeks of the year along with a coordinating central hand that indicates the current week.


The new automatic caliber 5134 is based on its predecessor, calibre 2120. It has been enlarged in accordance with the updated 41mm case size, although the watchmakers in Le Brassus managed to keep the thickness down to 4.31 mm.


Beating at 2.75Hz (19,800 vph) caliber 5134 has a bi-directional automatic winding rotor that is skeletonized in pink gold (can be custom decorated upon customer’s request). It has 38 jewels, 374 total components and a 40-hour power reserve.

The movement is highly finished and visible through the sapphire crystal caseback.


The retail price is $60,900 in steel (Ref. 26574ST.00.1220ST.01 – white dial, 26574ST.00.1220ST.02 – blue dial) and $95,700 in pink gold (Ref. 26574OR.00.1220OR.01 – white dial , 26574OR.00.1220OR.02 – blue dial).
