About the Audemars Piguet Perpetual Calendar

An Audemars Piguet Perpetual Calendar shows the day, date, month, week of the year, moonphase, and leap year, and it adjusts automatically for short months and February 29th. Set correctly, it will not need a date correction until the year 2100. WatchGuys carries pre-owned and unworn examples across the Royal Oak and Code 11.59 lines, and every piece is checked by our watchmakers before it is listed, including a full test of the calendar functions.

Which Audemars Piguet Models Come With a Perpetual Calendar?

Royal Oak Perpetual Calendar 26574. The reference most buyers know. It has a 41mm case, a Grande Tapisserie dial, and Calibre 5134, which uses small recessed pushers in the case side to correct the calendar. It comes in stainless steel, yellow gold, and rose gold, and it is the core of the Audemars Piguet Royal Oak perpetual market.

Royal Oak Perpetual Calendar 26674. The newest generation, with Calibre 7138. Every calendar function can be set from the crown, so you no longer need a corrector tool, and the power reserve rises to about 55 hours. It is offered in stainless steel, white gold, and AP's sand gold.

Ceramic Royal Oak Perpetual Calendars. The 26579CE in black ceramic and later blue ceramic versions are scratch resistant and noticeably lighter than gold. Find them alongside every other ceramic model in our ceramic Audemars Piguet collection.

Openworked Royal Oak Perpetual Calendars. Skeletonized versions show the calendar mechanism through the dial and sit at the top of the price range. See our skeleton Audemars Piguet collection.

Code 11.59 Perpetual Calendar. AP's round-cased 41mm line also offers a perpetual calendar in gold, usually for less than a Royal Oak with the same complication. Browse the Audemars Piguet Code 11.59 collection.

Earlier 39mm Royal Oak Perpetuals. The 25820 and 25654 are smaller, older references that come up occasionally and suit collectors who prefer a classic fit.

Audemars Piguet Perpetual Calendar Price

Most Royal Oak Perpetual Calendars sell between $100,000 and $500,000+. A steel 26574ST usually trades from about $105,000 to $135,000, depending on dial and completeness. Yellow gold and rose gold 26574 models often fall in a similar or slightly higher range. Ceramic versions generally start well above steel, and openworked and diamond-set models can pass $500,000. The new 26674 has a steel retail price of roughly $135,000, and supply is still limited. Vintage 39mm references and the Code 11.59 can come in below $100,000.

Royal Oak Perpetual Calendar vs. Patek Philippe Nautilus 5740

Both put a perpetual calendar in an integrated-bracelet sports watch. The Patek Philippe Nautilus 5740 comes only in white gold and usually costs more on the pre-owned market. The Royal Oak offers more case options, including steel and ceramic, and adds a week-of-year display. For Patek's traditional dress perpetuals, see Patek Philippe Grand Complications.

Common Questions

Audemars Piguet Perpetual Calendar FAQ

• What does an Audemars Piguet Perpetual Calendar do?

  It tracks the day, date, month, week of the year, moonphase, and leap year cycle, and it automatically accounts for months with 28, 29, 30, or 31 days. It will not need a date correction until 2100.

• What is the difference between the AP 26574 and 26674 Perpetual Calendar?

  The 26574 uses Calibre 5134 and needs a small corrector tool to adjust the calendar through pushers in the case side. The 26674 uses Calibre 7138, which lets you set every function from the crown and adds a longer power reserve of about 55 hours.

• How much does an Audemars Piguet Perpetual Calendar cost?

  Pre-owned Royal Oak Perpetual Calendars typically range from $100,000 to $500,000+. A steel 26574ST usually sells between $105,000 and $135,000, while ceramic, openworked, and diamond-set models sit higher.

• What happens if an Audemars Piguet Perpetual Calendar stops running?

  On the 26574 you will need to reset the calendar with the corrector pushers, in the correct order and outside the change window around midnight. On the 26674 you can reset everything from the crown. Many owners use a watch winder to keep the calendar running.

• Does the Audemars Piguet Perpetual Calendar hold its value?

  The steel and ceramic Royal Oak Perpetual Calendars have historically held value well and often trade near or above retail. Gold versions and the Code 11.59 tend to sell at a larger discount to retail, which can make them better value for buyers.

• How often does an Audemars Piguet Perpetual Calendar need servicing?

  Audemars Piguet generally recommends a service every five to seven years. Perpetual calendar movements have more parts than a standard automatic, so expect servicing to take longer and cost more.
