The central metric behind the momentum score. It filters out short-term swings and shows the true, medium-term market trend of this reference.
ℹ️ Volatility
Annualised price fluctuation. Below 10 % = very stable, 10–20 % = normal, above 20 % = volatile. With high volatility the price can change quickly — in both directions. Be cautious about buying without checking the current price.

ℹ️ Investment Grade A/B/C/D
ChronoCheck's own rating for each reference. A 0–100 point scale, made up of four weighted components:
- Momentum (40 pts) — trend strength from the momentum score.
- Liquidity (25 pts) — number of active live listings.
- Stability (20 pts) — inverse volatility — the calmer, the better.
- Source robustness (15 pts) — number of independent market sources.
- A · 75+ Trend is right, liquidity good, data broad.
- B · 55–74 Solid, but one component weaker.
- C · 35–54 Average, volatility or market breadth weigh on it.
- D · below 35 Downward or too little data — a collector's piece.

Audemars Piguet Ref. 26470IO.OO.A006CA.01 — Variants and collector names
Known as: Ghost, The Ghost, AP Ghost
Crystal variants
- Double Glareproofed Sapphire
The Audemars Piguet Royal Oak Offshore 26470IO.OO.A006CA.01 didn't earn its nickname by accident — it earned it outright: "Ghost," because the titanium case and dial dissolve into each other so completely they barely read as separate elements. Forty-two millimeters, executed entirely in Grade 5 titanium, with a smoky grey dial that shifts between near-transparent and anthracite depending on the light hitting it.
## What Has Kept the Market Hooked Since 2013
AP introduced the first Ghost generation in 2013 as a deliberate counterpoint to the louder end of the Offshore lineup. Collectors with a feel for restraint moved immediately. The list price at the time was around 22,400 euros; today the 26470IO trades on the secondary market between 19,000 and 26,500 euros, depending on papers and condition. A sealed box with complete documentation pushes the range upward; a polished case pulls it back down.
## The Calibre Impresses, the Name Decides
The 3126/3840 does its job quietly: 55 hours of power reserve, 280 components, no surprises. But what actually drives collector interest is something else entirely. The Ref. 26470IO is one of the very few Offshore variants that circulates simultaneously under three names within the community — Ghost, The Ghost, and AP Ghost. Three nicknames for a single reference is not coincidence; it is a reliable indicator of a cultural footprint that reaches well beyond the usual enthusiast niche.
## Patience Is Part of the Search
Active listings rarely appear two at a time. In the European market, 4 to 6 examples are typically available in parallel — and that is during a year with healthy liquidity. Finding a piece on its original blue rubber strap with a traceable single-owner history realistically requires 6 to 12 weeks of active searching.
Brand profile: Audemars Piguet
AP Royal Oak is one of the most coveted and most counterfeited luxury watches. The distinctive octagonal bezel with 8 screws and the tapisserie dial are the central inspection points.
- Date disc: genuine caliber 3120/5120 flips the date INSTANTLY at midnight (a snapping jump) — clones creep from 23:00 to 01:00
- Thickness: Royal Oak Jumbo 15202 is exactly 8.1 mm thick — clones measure 8.4–8.8 mm (movement sits too tall) — calipers reveal it immediately
- Tapisserie dial: under 10× magnification the pyramid edges must be sharp and geometrically precise — fakes show soft, pressed, or laser-etched surfaces
- Bezel screws: 8 hexagonal screws with mirror polishing and exact alignment — fakes: flatter, duller, asymmetric
Serial number format: AP serial numbers: 6–7-digit number engraved between the lugs at 9 o'clock. Reference number engraved separately on the opposite side. Very small — barely legible without a loupe.

What drives the price here
At $39,637 the watch sells well if the condition is right. A market rule of thumb: a complete set with box, papers and warranty card brings 10 to 15 percent more than the bare watch. Buying without papers can pay off, but you take the same discount again later when you resell.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Audemars Piguet Royal Oak Offshore Chronograph reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Royal Oak Offshore Chronograph.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
