Authentication
The flying tourbillon has no upper bridge; a cage supported from above is a different caliber or a non-genuine movement.
Known issues in the market
- Given the price point and limited production, most examples circulate through AP boutiques or well-documented secondary dealers; buy history and full box/papers matter more than usual here.
- The GMT function and flying tourbillon must be checked independently; a stopped or dragging tourbillon indicates the movement needs immediate service, not casual use.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| movement | Flying tourbillon construction | Tourbillon cage at 9 o'clock is unsupported from above (flying), visible in full from the dial side; rotates smoothly with no drag | A visible upper bridge over the tourbillon cage; any stutter or drag in the cage rotation |
| case | Sandblasted titanium finish and ceramic bezel | Uniform matte sandblasted texture on the titanium case; grey ceramic bezel with polished bevels, no chips or scratches through the glaze | Glossy or polished case finish inconsistent with sandblasted titanium; chipped ceramic exposing a different substrate underneath |
| dial | GMT indicator and crown-position indicator | Second-time-zone indicator at 3 o'clock reads independently of the main hands; crown-position indicator at 6 o'clock correctly shows the selected winding/setting mode | GMT hand slaved to the main hour hand; crown-position indicator missing or not changing with crown position |
Common legitimate replacements
- No common replacements; Royal Oak Concept parts are proprietary AP and effectively unobtainable outside AP service.
