You own the exact reference
Use the checklist and current-mandate intake. The watch still needs its own condition, ownership and documentation review.
Reference guide · Audemars Piguet
The Audemars Piguet Royal Oak Perpetual Calendar Openworked 26585CE.OO.1225CE.01 combines black ceramics with an openworked sapphire dial. Passion Asset Advisory has an active acquisition mandate for this exact reference. A different black-ceramic or openworked Royal Oak is not automatically a match. This guide separates reference identification, the current buyer brief and the evidence needed before an offer.
Identify the execution
| Field | Published identity | How to use it |
|---|---|---|
| Collection and model | Royal Oak Perpetual Calendar Openworked | Keep the complete model name, not just “Royal Oak.” |
| Full reference | 26585CE.OO.1225CE.01 | Match the whole reference against the watch and its records. |
| Material description | Black ceramics | Colour alone does not identify the reference. |
| Dial | Openworked sapphire dial | Record the actual watch; a catalogue image is not an inspection. |
| Current price or stock | Not established by this guide | Do not read catalogue presence as an available watch or purchase offer. |
Source: Passion Asset Advisory's reference check against Audemars Piguet's official 26585CE.OO.1225CE.01 page, reviewed 10 October 2026. The last row states this guide's evidence limit, not a manufacturer price.
AP's description places visible pink-gold movement components behind the sapphire dial. That open view helps explain the model's appearance; it does not establish the originality, condition or correct operation of a particular watch.
Names are not interchangeable
The manufacturer uses “Perpetual Calendar Openworked” as the model name for the reference above. Keep the complication, dial description and material together. Searching only for a black-ceramic AP or an openworked Royal Oak can produce watches outside this specific brief.
| Description you have | What still needs checking | Decision |
|---|---|---|
| “Royal Oak perpetual calendar” | Full reference, material and whether the dial is the specified openworked execution. | Do not assume that the family name matches 26585CE. |
| “Black-ceramic openworked AP” | Model name, complication and complete reference. | A similar appearance does not establish the required model. |
| 26585CE.OO.1225CE.01 in the records | The physical watch, condition, included set and any changed components. | Proceed to a reference-specific review, not an automatic acceptance. |

Current acquisition brief
Passion Asset Advisory is seeking the Royal Oak Perpetual Calendar Openworked, black ceramic, Ref. 26585CE.OO.1225CE.01 under an active acquisition mandate. The shared AP mandate record is the place to check its current scope and status.
Send the reference, condition, available set, service history and country where the watch is now. The reply checks the proposed watch against the brief. Written terms identify the represented side, fees, inspection and completion conditions before any transfer. An active mandate is not an accepted offer for an unexamined watch.
Mandate scope confirmed by Passion Asset Advisory on 10 October 2026. Manufacturer information identifies the watch; it does not confirm PAA's buyer mandate or budget.
Prepare a useful record
Use the manufacturer's instructions for operating or setting the watch. This identification guide is not a service manual. If its operation is uncertain, explain the issue and arrange a qualified assessment rather than trying to correct it for a sale photograph.
An archive extract and a manufacturer's authenticity certificate are different documents. AP explains that the certificate requires its examination of the watch, while an extract confirms recorded numbers. See the official AP document services. The office's preliminary review does not issue a manufacturer's certificate.
Price needs matching evidence
This guide does not establish a current retail quote or a verified completed-sale range for 26585CE.OO.1225CE.01. An asking price for a different black-ceramic AP is not a substitute. An active acquisition brief also does not publish the buyer's budget or fix the price of every matching watch.
For a value review, identify the same reference and record each comparable's date, currency, condition, set and price basis. State gaps rather than filling them with results for another complication or material. Use the AP value guide to distinguish those figures and expected seller net.
If you are comparing a purchase offer with a consignment proposal, use the AP sale-route comparison. The price proposed, fee, custody terms and settlement trigger belong together. A hoped-for listing amount is not the same commitment as a written offer.
Choose your next step
Use the checklist and current-mandate intake. The watch still needs its own condition, ownership and documentation review.
Use the general AP seller review. Do not relabel the watch to fit this brief or assume another reference has a confirmed buyer.
Discuss a separate collector-watch acquisition brief. This page is a guide and an owner invitation, not a listing for a watch in stock.
This is not a guide to every Royal Oak perpetual calendar, a remote certificate of authenticity or a forecast of appreciation. The complete reference and the intended transaction decide the next step.
FAQ
AP identifies it as the Royal Oak Perpetual Calendar Openworked in black ceramics, with an openworked sapphire dial. Keep the complete reference with the watch's records. The model name and a catalogue image do not establish the condition or authenticity of an individual example.
No. Match the full reference and the manufacturer's model description, not just the colour or visible movement. The active Passion Asset Advisory brief on this page is specifically for 26585CE.OO.1225CE.01. Another reference requires a separate review and does not automatically qualify.
No current retail quote or verified completed-sale range is established here. A reference-specific review needs matching evidence, condition and set details, and the intended sale route. A dealer's asking price and an active acquisition mandate are not firm offers for your watch.
Yes. The office confirmed an active acquisition mandate for the black-ceramic Royal Oak Perpetual Calendar Openworked, 26585CE.OO.1225CE.01, on 10 October 2026. Check the shared current-mandate record before proceeding. Each proposed watch remains subject to reference fit, condition, ownership, documentation and agreed inspection and completion terms.
Yes, through the general AP seller-review route. Supply the exact reference rather than treating it as a match for 26585CE.OO.1225CE.01. Reviewing another watch does not mean the office has an active buyer for it or has agreed a purchase price.
No. Start with the text enquiry and provide photographs in the private email exchange. Written terms should identify the counterparty, represented side, inspection arrangements, insured custody, return conditions and payment trigger before any watch moves. An enquiry is not an instruction to ship.
Sources and limits
The official reference and document-service information were reviewed on 10 October 2026. Manufacturer facts identify the design; the office's separate mandate record identifies the watch sought. No dealer listing has been treated as a completed sale, and no current price or available stock is asserted.
The office is independent of Audemars Piguet and is not an authorised AP dealer. A written engagement sets out the represented side, role, fees and completion conditions. No offer, sale price, allocation or future return is guaranteed.
