The purple Audemars Piguet Royal Oak Perpetual Calendar is reference 26598BC.ZZ.1220BC.01: a 41 mm 18-carat white-gold watch with a purple Grande Tapisserie dial and baguette-diamond bezel. AP’s current product page lists its specifications and offers a boutique appointment path, but does not show a public price. A 2022 report called it boutique-exclusive and priced on request; that historical description does not establish today’s stock or price.
What is the purple AP Royal Oak Perpetual Calendar 26598BC?
It is a diamond-set, white-gold version of the Royal Oak Perpetual Calendar. Audemars Piguet identifies the full reference as 26598BC.ZZ.1220BC.01 and describes its vivid purple Grande Tapisserie dial alongside a bezel set with baguette-cut diamonds. The Royal Oak family debuted in 1972; that history is useful context, but it is not the launch date of this specific purple reference. Audemars Piguet’s Royal Oak collection page outlines the collection’s origins and design identity.
The watch retains the Royal Oak’s integrated-bracelet form, while its purple dial and diamond-set bezel give this perpetual-calendar model a notably high-jewelry treatment. The dial has purple counters with a white outer zone, white-gold applied hour markers and luminous Royal Oak hands, plus a purple inner bezel. Monochrome’s 15 December 2022 description characterized the shade as a warm purple approaching burgundy—an editorial impression rather than an official color specification—and reported 32 baguette-cut diamonds.

The 20 m water-resistance rating is a specification, not a recommendation to use this diamond-set perpetual calendar as a swimming or diving watch. For handling, setting and care, use the instructions for the exact reference rather than relying on a general claim about perpetual-calendar correction intervals.
How much does the AP 26598BC cost?
AP’s current public page does not render a price. Monochrome reported in December 2022 that the watch was boutique-exclusive and that its price was available on request. That is launch-era reporting, not a current quote or confirmation of present-day sales conditions. For current regional pricing and authorized purchase options, use AP’s product page for reference 26598BC.ZZ.1220BC.01 and contact a boutique.

Is the purple Royal Oak Perpetual Calendar available now?
AP currently lists the model and provides a boutique appointment path, but the public page alone does not confirm stock, production status or availability in a particular region. Monochrome’s 2022 description of the model as boutique-exclusive should be treated as historical. Ask AP or a boutique to confirm whether the exact reference can currently be ordered or viewed where you are.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why do published movement specifications differ?
AP’s current page lists Calibre 5134 at 4.5 mm thick with 374 parts. Monochrome’s 2022 article gave 4.3 mm and 365 components for the calibre. These are conflicting published figures; the current manufacturer page is the appropriate source for the present product specification. Do not combine the two sets of numbers as if they described one confirmed specification.

- Refined Swiss Engineering: The quartz watch movement is powered by a battery. The quartz movement provides precise timekeeping and requires minimal maintenance, making it a reliable and worry-free timepiece.
- Caring for Your Timepiece: Like any finely crafted mechanism, your Movado watch requires periodic maintenance to ensure optimal performance. A maintenance interval of 3 to 5 years is recommended, in addition to any required battery replacement. Never open the watch yourself.
- Water Resistant: Up to 30m (100 ft): Will withstand splashes or brief immersion in water, but not suitable for swimming or showering; 3 ATM.
The broader Royal Oak Perpetual Calendar lineage dates to the mid-1980s, according to Monochrome. The publication also places the 41 mm format and week display in a 2015 revamp. Those milestones describe the family’s development, not the introduction date of reference 26598BC.ZZ.1220BC.01.
